Most people shopping for an FM2 processor are trying to squeeze life back into a board they already own. The trick is matching the chip to your socket and your memory, because a fast processor on the wrong socket is a paperweight. This guide sorts the real FM2 and FM2+ options from the ones that simply will not fit, and points out which pick suits a repair, a budget build, or a light gaming box.
This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
You will see which chips need fast RAM to shine, which ones run hot, and which bundle a cooler you can actually leave in place. Read on for a clear, plain-English look at the best FM2 Processor options that fit an older AMD board without a rebuild.
Top Picks
How To Choose The Best FM2 Processor
An FM2 processor only earns its place if it drops into the board you already have. Before you compare clock speeds, confirm the socket, the memory the board supports, and the heat the chip throws off. Get those three right and the rest is trimming.
Match the socket first, not the spec sheet
FM2 and FM2+ look alike but are not the same slot. An FM2+ chip generally drops into an FM2+ board, while older FM2 boards need checking on the maker’s compatibility page. One chip here is a Socket AM4 part, a whole different platform, so it only fits a newer board and will not touch an FM2 slot at all.
Fast memory is not optional on an APU
An APU is a chip that combines the processor and the graphics on one piece of silicon. That graphics half borrows from your system memory, so the memory speed feeds it directly. On these APUs, 1,866MHz or 2,133MHz DDR3 feeds the graphics core directly, and buyers report smoother play than with slow sticks.
Plan for the heat and the cooler
The figure to watch is thermal design power, or TDP — the heat a chip produces under load. A 65W chip runs comfortable on the bundled cooler, while a 95W chip tends to run hot and rewards a taller tower cooler. Several picks here include a cooler in the box, which saves a separate purchase.

Detailed Reviews
1. AMD Ryzen 5 5500 Desktop Processor
Our pick — 4.5+★ from 11,500+ verified ratings; the strongest balance of quality and price.
Six cores and twelve threads that turn a tired desktop into a smooth multitasker.
This is the pick for anyone building or upgrading a modern AM4 system rather than patching an FM2 board. Its headline is six cores and twelve processing threads, which means it can juggle a game, a browser with a dozen tabs, and a background recording without grinding to a halt. The 4.2 GHz Max Boost figure is the top speed it reaches when a task needs one fast core, and there are 19 MB of cache to keep frequently used data close at hand.
What wins people over is raw grunt for a mid-range tag. Streaming is where it shines: owners running 1080p 60FPS at 6000kbps report CPU usage settling around 12–15% while the game and broadcast run together. Video rendering, heavy multitasking, and 1080p gaming on a separate graphics card all land comfortably. It ships with the Wraith Stealth cooler and pre-applied thermal paste, so you do not need to buy a separate cooler to get running.
The catch is the platform. This is a Socket AM4 part, so it will not drop into an FM2 or FM2+ board at all — you need the newer socket and DDR4 memory. It also sticks to PCIe 3.0, an older slot standard for graphics cards, which costs a little pace on the fastest modern cards. A dedicated graphics card is still required for gaming since there is no built-in graphics. The crowd verdict is warm: 4.5+ stars across 11,000+ owners.
Where it pulls ahead
- Six cores and twelve threads handle streaming and rendering at the same time
- 4.2 GHz Max Boost keeps single-task work snappy
- Wraith Stealth cooler and thermal paste come in the box
- On-chip streaming load stays low, so game and broadcast run together
The trade-offs to weigh
- AM4 socket only — it will not fit an FM2 or FM2+ board
- PCIe 3.0 limits pace on the fastest graphics cards
- No built-in graphics, so a separate card is needed for games
- The bundled cooler is stable but a tower cooler runs quieter under long loads
Go for it when: you are building or refreshing an AM4 desktop for streaming, editing, or 1080p gaming on a graphics card.
Look elsewhere when: you own an older FM2 or FM2+ board — this chip needs the AM4 socket and DDR4 memory.
2. Intel Core i7-6700 Processor
A four-core workhorse that stays cool and quiet through a long day.
If your goal is a dependable everyday machine for office work, media, or a bit of editing, this chip earns its place on calm rather than raw speed. It runs four cores and eight threads at a 3.40 GHz base clock, with a 4.0 GHz Turbo Boost reach when a task needs a quick lift. The 8 MB cache and support for both DDR4-2133 and low-voltage DDR3L memory make it flexible to pair with a range of older boards.
Owners prize the low heat: with a good air cooler it idles in the low thirties Celsius and barely warms under heavy music or video work. Fans rarely spin up, which makes it a fine fit for a home office where you notice noise. Installation is simple and it stays stable over long stretches. It also includes an Intel HD 530 graphics chip, so a basic display works without a separate card.
Two honest notes. It is a locked chip, so you cannot overclock it for extra pace — that suited buyers who want predictable performance rather than tinkering. And it needs an LGA 1151 board and is compatible with the Intel 100 Series chipset, not the LGA 1155 slot that some older listings name. The bundled stock cooler does its job, though buyers chasing silence swap for a bigger air cooler.
What lands well: low idle heat, simple install, and enough threads for office multitasking. It outperforms the older dual-core parts it often replaces, so older DDR3 systems get a visible lift.
What to know: no overclocking and a locked multiplier — if chasing raw speed matters more than quiet, a Ryzen 5 5500 on a newer board offers more cores for the money.
The right fit: a quiet home-office or media machine that runs cool and stays stable.
Think twice if: you want to overclock or need a chip for an LGA 1155 board — this one is LGA 1151 only.
3. AMD A8-7650K Black Edition APU
Ten compute cores in one chip let you skip a graphics card entirely.
This APU bundles the processor and the graphics onto one slab of silicon. You get 4 CPU cores plus 6 graphics cores, which AMD labels as 10 compute cores, running the CPU at a 3.3 GHz base that boosts to 3.8 GHz. The Radeon R7 graphics runs at 720 MHz, so light games and everyday video work without a separate card.
It leans on fast memory to feed that graphics half, and it supports DDR3 at 2,133 MHz. Pair this APU with 2,133MHz DDR3 and the Radeon R7 graphics gets the bandwidth it needs; slow sticks leave it starved. It fits the FM2+ socket and draws 95W, and it ships with a near-silent 95W AMD thermal solution — a notable bonus for a budget build that wants to keep noise down.
Here is the honest part: a 95W chip runs hotter than the 65W parts, and a buyer who saw HD transcoding pushing temps into the 90s found it wants airflow. The stock cooler attaches with tie-downs that take some fiddling, and fitting a non-stock cooler voids the warranty. The performance consensus is strong: 4.5+ stars across a smaller pool of owners.
Why it suits a no-GPU build
- 4 CPU cores plus 6 graphics cores in one chip
- Radeon R7 graphics at 720 MHz handles light gaming
- 3.8 GHz CPU boost keeps everyday tasks brisk
- Near-silent 95W cooler included in the box
What to plan around
- 95W draws more heat than a 65W chip and needs airflow
- Stock cooler tie-downs take some fiddling to seat
- Non-stock coolers void the warranty
- Needs fast DDR3 to get the most from the graphics
Reach for this if: you want one chip to handle both the work and the graphics on an FM2+ board.
Skip the swap if: you need upgrade room — the 95W draw and warranty terms reward leaving the included cooler in place.
4. AMD A10-7850K APU AD785KXBJABOX
A four-core APU that plays most games at medium settings without a card.
For a home or office build on the FM2+ socket, this chip is a balanced all-rounder. It packs four CPU cores alongside Radeon R7 graphics and uses AMD’s H.S.A. architecture, so the processor and graphics share work efficiently. That setup is why it can run a web browser, a media player, and a light game at once without a dedicated graphics card.
Owners talk about how far it stretches for the money — it drives dual monitors at their native resolution, handles Photoshop and InDesign, and plays undemanding games at medium settings. One point that comes up again and again: this chip craves fast RAM. Pair it with 2,133MHz memory or faster, and the graphics half has the bandwidth it needs. Energy use is modest at idle, and overclockers report automatic clocks well above the stock setting holding stable.
The real caution is heat and expectation. A 95W chip runs warm, so a taller cooler like a Hyper 212 Evo serves it far better than the stock fan. And while it plays most games at medium, it is not a high-end gaming chip — blockbuster titles at max settings need a dedicated card. The everyday-PC crowd is happy with it, sitting at 4.0+ stars across hundreds of owners.
The thing buyers notice: it runs a full desktop — multiple monitors, streaming video, editing apps — with no graphics card at all. When paired with 2,133MHz memory or better, it handles light gaming with room to spare.
The honest limit: the 95W heat output wants a real cooler, and max-settings blockbusters will want a dedicated card.
Best matched to: an everyday FM2+ desktop that wants graphics without buying a card.
Avoid if: your plan is high-end gaming at max settings — that needs a dedicated graphics card this APU cannot replace.
5. Advance Micro Device Radeon HD8570D Quad Core Dual Graphics Processor 4.3 4 AD660KWOHLBOX
Four cores and on-chip Radeon HD8570D graphics for a small, cheap gaming box.
This one suits a compact build where you would rather not add a graphics card. It is a quad-core CPU with Radeon HD8570D graphics built in, sitting on the FM2 socket. It carries AMD Turbo Core 3.0 to lift speed when a task calls for it, and it is open up for those who like to push it a little further.
The integrated graphics earn real praise: players run Counter-Strike Source without a dedicated card at all, and Skyrim plays on high. Below that, owners who want more can add a separate card, since it supports Dual Graphics. Overclockers report stable bumps well above stock, so there is headroom if you enjoy tuning. Buyers hunting a cheap starter rig consistently call it great value for entry-level gaming.
Two practical notes. One is the heatsink — the stock cooler is small, and moving to a larger air or water cooler visibly drops temps. The other comes up often: grab the latest drivers from AMD’s site before gaming, because the out-of-box drivers are outdated. Keeping that in mind, the quad-core build is friendly to a modest budget.
What it brings to a small build
- Quad-core CPU with Radeon HD8570D graphics on the FM2 socket
- Plays Counter-Strike Source and Skyrim on high without a card
- open up and overclockable for extra pace
- Dual Graphics support leaves room to add a card later
What to keep in mind
- Stock heatsink is small — a bigger cooler noticeably improves temps
- Out-of-box drivers are outdated and need a fresh download
- Onboard graphics suit light games, not high-end titles
- Older FM2 socket limits upgrade paths
Works best for: a small, low-cost gaming build that will lean on the on-chip graphics.
Heads up: budget a little extra for a bigger cooler — the small stock heatsink runs warm under load.
6. AMD FX-8300 Black Edition Processor
Eight cores on an old AM3+ board keep an aging rig in the game.
This is for the buyer holding onto an AM3+ motherboard and wanting more without a full rebuild. It is an eight-core chip at a 3.3 GHz operating frequency, with a shared L3 cache and dual 128-bit floating point engines that can team up for 256-bit AVX instructions. That is a lot of numbers, but the practical read is simple: eight cores spread the load when you game and multitask together.
The 95W figure is the reason many pick this over faster-clocked FX models — the higher-wattage versions throw off more heat. Owners upgrading from older FX-4100 chips report a clear jump, holding 60 FPS in demanding titles at high settings on the same AM3+ board. It is open up, and one tuner reports air-cooled clocks up to 4.7GHz. The eight-core value here is genuine for the aging platform.
The honest trade-off is heat and the bundled cooler. The stock fan is the weak link — owners regularly swap to a tower cooler like a Hyper 212 or better, and the chip is happiest with that airflow. It is also old technology, so a comparable Intel part is simply faster, though it usually costs more. A buyer on an AM3+ board generally finds the value impossible to argue with.
The selling point: eight cores keep a whole old platform useful — multitasking, gaming, and even running a Linux desktop. Upgrades from older FX chips are dramatic.
The caveat: it runs hot, so budget for a proper tower cooler; the stock unit is not enough for heavy loads.
For you if: you already own an AM3+ board and want the biggest lift without replacing it.
Pass on it if: you are starting fresh — a newer AM4 chip beats it on both speed and heat.
7. AMD A Series Processor 3.5 2 AD740KYBJABOX
Two cores and onboard graphics that bring a dying desktop back to life.
For the smallest of budget builds and simple everyday desktops, this dual-core APU does the trick. It runs two cores and two threads at a 3.5 GHz base that boosts to 3.9 GHz, with 1 MB of L2 cache. It draws a modest 65W, so it runs cooler than the higher-wattage chips in this lineup and asks less of your power supply.
The graphics half is where it surprises. Buyers reviving old PCs report League of Legends at 1080p hitting 60-80fps, CS:GO at 720p in the mid-50s to 60, and Grid Autosport at 720p in the 60-70 range, all on the onboard graphics. For a two-core chip with no separate card, that is competitive light gaming. It sits on the FM2+ socket, so check your board support, and note it wants fast memory in the 1,866 to 2,400MHz range to feed the graphics.
The catch is heat-sensor behavior and Turbo. When Turbo is on, some owners see temps climbing to the point of throttling, and disabling Turbo or fitting an aftermarket cooler keeps things calm. A handful of boards also hit compatibility snags, so verify the model on the maker’s site. Keep those in mind and the value read is strong, with solid satisfaction from owners who bought it for exactly this job.
Where the value sits
- 2 cores at 3.9 GHz boost for everyday and light gaming
- 65W draw runs cooler than higher-wattage parts
- Onboard graphics handle League of Legends, CS:GO, and more
- Revives old FM2+ PCs without a graphics card
What to plan for
- Turbo can push temps to throttling — disable it or add a cooler
- Wants fast 1,866-2,400MHz memory for the graphics
- Two cores is a ceiling for heavier workloads
- Some older boards hit compatibility snags — check yours first
Suits a cheap rescue: an old FM2+ desktop that needs to run office apps and light esports games.
Don’t expect more: two cores and 1 MB cache cap heavy video work, so look to a higher-chip pick for serious workloads.
Know the Specs
Socket types
The socket is the physical slot the processor plugs into, and it has to match your motherboard exactly. FM2, FM2+, AM4, LGA 1151, and AM3+ are all different shapes — a chip only fits the slot it was built for. Always check your board’s socket before you buy, because a mismatched chip simply will not go in.
Core count and threads
Cores are the processors inside the processor that each handle a task, and threads are the streams of work they can run. More cores and threads mean a chip can juggle more at once — gaming while streaming, or editing while browsing. The move from two cores to six or eight is what keeps an older system feeling responsive.
TDP and cooling
Thermal design power (TDP) is the heat a chip puts out under load, measured in watts. A 65W chip runs comfortable on a stock cooler; a 95W chip tends to run warmer and rewards a taller tower cooler. Pairing a hot chip with a small cooler leads to throttling, where it slows itself down to protect against heat.
Memory support and APU graphics
An APU has graphics built into the chip, and that graphics half borrows from system memory to work. That is why memory speed matters so much here — 1,866MHz or 2,133MHz modules feed the graphics better than slow sticks. Standard processors without built-in graphics need a separate graphics card to output a display.

The Bottom Line
For most people shopping for the fm2 processor, the winner is the AMD Ryzen 5 5500 because its six cores and twelve threads turn streaming, editing, and 1080p gaming into smooth work — provided you have an AM4 board rather than an old FM2 slot. If you are holding onto an FM2+ board and want graphics without a separate card, grab the AMD A8-7650K Black Edition. And for breathing life into an AM3+ rig, the AMD FX-8300 is the one to reach for. The crowd favorite here sits at 4.5+ stars across thousands of owners, and the cooling and multitasking strengths behind that score are exactly why it tops the list.
