How To Choose The Best Cheap Processor
A budget CPU is a compromise, but the right one keeps your PC feeling fast for years. Focus on three specs: core and thread count (how many tasks the chip can handle at once), cache size (a small, ultra-fast memory pool that makes apps load snappily), and if you need integrated graphics (a built-in video chip) to skip buying a separate graphics card right away.
Core Count and Thread Count
More cores and threads let your processor handle several tasks at once without slowing down. A 4-core, 8-thread chip is the balance for a cheap processor — it runs web browsing, office apps, and light gaming without choking. A 2-core, 4-thread chip works for a basic server or a single-task machine, but you will feel the lag if you open too many browser tabs.
Cache Memory
Cache is a small pool of super-fast memory built into the processor that holds data the CPU needs instantly. More cache (measured in MB) means the chip spends less time waiting for data from your main RAM, making everyday tasks feel snappier. 6 MB is a good floor for a budget desktop; 18–20 MB is noticeably better for gaming and multitasking.
Integrated Graphics
A processor with built-in graphics (called an APU by AMD, or just “with graphics” by Intel) lets you plug a monitor directly into the motherboard and get a usable display without buying a separate graphics card. This can shave – off your build. The trade-off is that integrated graphics are weak for modern 3D games — you will need a dedicated GPU for titles like Cyberpunk 2077 or Call of Duty.

In‑Depth Reviews
1. AMD Ryzen™ 5 5600G 6-Core 12-Thread Desktop Processor with Radeon™ Graphics
The cheap processor that plays popular games at 1080p without a separate graphics card.
You get 6 cores and 12 threads with a 4.6 GHz Max Boost speed, and its 20 MB cache makes loading applications feel quick. The built-in Radeon graphics are the fastest processor graphics on the market, so you can play games like Elder Scrolls Online or Fallout 4 at 1080p without buying a dedicated GPU. It supports DDR4-3200 memory and fits the Socket AM4 platform — a mature ecosystem with affordable motherboards.
Buyers report the stock cooler keeps the chip at 70 degrees under load and 60 degrees with better airflow, which is perfectly fine for a budget build. The 5600G is open up for overclocking, so you can squeeze more performance later when you upgrade your cooling. One reviewer noted it handles 15 Chrome tabs open while streaming without any slowdown.
What You Get
- Fastest integrated graphics in its price range — plays many games at 1080p
- 6 cores and 12 threads beat budget quad-core chips for multitasking
- Stock cooler is adequate for everyday use
The Trade-Off
- PCIe 3.0 instead of 4.0 limits GPU bandwidth with very fast cards
- Needs a BIOS update on older B350 boards before it works
Reach for this if: you want a single chip that handles both everyday computing and light gaming at 1080p without spending extra on a graphics card.
Look elsewhere if: you already own a high-end GPU and want PCIe 4.0 support — the Ryzen 5 5600X would fit better.
2. Intel Core i5-12400 Desktop Processor 18M Cache, up to 4.40 GHz
Pure CPU muscle for demanding apps and blistering 1080p gaming with a dedicated GPU.
With 6 performance cores and 12 threads, the i5-12400 hits a 4.40 GHz turbo boost speed and packs 18 MB of L3 cache (the fast memory the CPU uses to store frequently accessed data). Its single-core speed is faster than the Ryzen 5 5600G, which gives it a slight edge in games that rely heavily on one core. The built-in Intel UHD Graphics 730 handles office work, media encoding, and a second monitor, but you will want a dedicated graphics card for serious gaming.
Owners mention that the i5-12400 runs cool with a large air cooler and matches its advertised speeds easily. One reviewer called it “best bang for your buck” for a budget CPU. The chip comes with thermal paste pre-applied, though some owners recommend an aftermarket cooler like a Cooler Master to keep noise low under heavy loads.
What You Get
- Fast single-core performance beats most budget chips in gaming
- 18 MB L3 cache speeds up app loading and multitasking
- Integrated UHD 730 graphics work for media and office without a GPU
The Trade-Off
- LGA1700 platform is a dead end — no upgrade path without a new motherboard
- Stock cooler is a bit weak for sustained heavy workloads
Best suited for: builders who already have a dedicated graphics card and want the fastest possible CPU performance for games and daily tasks at a low price.
Avoid if: you plan to upgrade the CPU in the same motherboard later — the LGA1700 socket has no future.
3. AMD Ryzen 3 4100 4-Core, 8-Thread open up Desktop Processor with Wraith Stealth Cooler
A four-core open up chip that punches above its weight for budget AM4 builds.
The Ryzen 3 4100 gives you 4 cores and 8 threads with a 4.0 GHz Max Boost speed and 6 MB of cache. Unlike the Ryzen 3 2200G, it does not have integrated graphics, so you must pair it with a dedicated GPU. The chip is open up for overclocking, meaning you can push it beyond stock speeds if your cooling allows. It supports DDR4-3200 memory and fits the Socket AM4 platform, which is the same socket used by many higher-end Ryzen chips.
Customers note that after a BIOS update, the CPU worked perfectly, providing a significant speed boost for VMs and Discord bots with minimal lag. One buyer mentioned it runs warmer than 65W models like the 5500 or 5600, so a decent aftermarket cooler is a smart addition. The Wraith Stealth cooler included in the box will handle normal use, but you might want something better if you overclock.
Why It Shines
- 4 cores and 8 threads handle multitasking far better than 2-core chips
- open up multiplier lets you overclock for extra performance
- AM4 platform offers an easy upgrade path to a Ryzen 5 or 7 later
The Catch
- No integrated graphics — you must buy a separate GPU to get a display
- Runs warmer than higher-end 65W Ryzen chips under load
Grab this for: a budget AM4 build where you already have a graphics card and want the option to overclock now or upgrade to a faster Ryzen later.
skip it if: you need a display output right away — get the Ryzen 3 2200G with integrated Vega graphics instead.
4. AMD YD2200C5FBBOX Ryzen 3 2200G Processor with Radeon Vega 8 Graphics
Integrated Vega 8 graphics that play older games without a dedicated GPU.
The Ryzen 3 2200G is a 4-core, 4-thread chip (no multithreading, so it handles 4 tasks at once) with a 3.7 GHz Max Boost speed and 6 MB of cache. Its standout feature is the built-in Radeon Vega 8 graphics, which let you play Minecraft and Team Fortress 2 at reasonable framerates without a separate graphics card. It comes with a Wraith Stealth cooler, so installation is plug-and-play.
Reviewers point out that overclocking the integrated GPU to 1500-1600 MHz can boost framerates by 20-35%, but this requires better cooling. One owner used it as a 4K media PC (HTPC) and said it offers excellent value for the price, as long as you update the BIOS and install the latest chipset drivers. Unlike the Ryzen 3 4100, this chip has no multithreading — only 4 threads — which limits heavy multitasking.
The Upside
- Integrated Vega 8 graphics play older games without a separate GPU
- open up for overclocking — GPU overclock can boost framerates significantly
- Wraith Stealth cooler included in the box
The Downside
- No multithreading means only 4 threads — lags in heavy multitasking
- Maximum memory speed is 2667MHz, slower than newer chips
Pick this if: you are building a budget media PC or light gaming rig and want to skip buying a graphics card entirely.
Pass on it if: you need strong multitasking performance — the Ryzen 3 4100 with 8 threads is a better choice.
5. Intel Core i3-9100 Desktop Processor 4 Cores up to 4.2 GHz LGA1151 300 Series 65W
A solid quad-core from a few years back that still makes a great office PC or media server.
The i3-9100 is a 4-core, 4-thread processor with a 4.2 GHz turbo boost speed, 6 MB of cache, and built-in Intel UHD Graphics 630. It fits LGA1151 motherboards with the Intel 300 Series chipset (the same socket used by older 8th and 9th gen CPUs). It draws only 65W of power, making it an efficient choice for a basic office machine or a home media center.
One owner reported moving from an i5-6400 to this i3-9100 and found it was “actually an upgrade” — the i3 outperforms the i5 in benchmarks by 17% and feels noticeably more peppy. Another reviewer noted that without a graphics card, this CPU along with 16 GB of RAM and an Intel 660P NVMe SSD makes a rock-solid 10-year office computer. At 4 cores and 4 threads, it struggles with modern gaming, but for browsing, email, and office apps it works fine.
What Works
- Integrated UHD 630 graphics mean no GPU needed for basic use
- 65W TDP keeps power bills low and heat minimal
- Up to 4.2 GHz boost is fast enough for everyday apps
What Limits It
- Only 4 threads — heavy multitasking shows lag
- Uses the older LGA1151 platform with no modern upgrade path
Ideal for: a simple office PC, a media server, or a build for a family member who only browses the web and checks email.
Not for: modern gaming or heavy multitasking — the i5-12400 or Ryzen 5 5600G would serve you much better.
6. Intel Pentium Gold G6405 4.1GHz 4MB Desktop Processor Boxed
A tiny, ultra-cheap chip that revived a NAS with low power consumption and basic speed.
The Pentium Gold G6405 is a 2-core, 4-thread CPU running at a fixed 4.1 GHz (no turbo boost needed) with 4 MB of cache. It uses the FCLGA1200 socket and is compatible with 10th-gen Intel boards. It draws minimal power and includes integrated UHD 610 graphics, so you can run a basic desktop or a network-attached storage (NAS) box without a separate GPU. The boxed version does not include a cooler, so you will need to buy one.
One reviewer wrote: “For a time I looked down on Pentium processors as weak but I will no more.” They used it to give new speed to their NAS and called it a great value for the money. Compared to the AMD Ryzen 3 4100, this chip has only 2 cores vs 4, and 4 MB cache vs 6 MB — a significant gap in multitasking ability. It works for single-purpose machines, but do not expect smooth multitasking with many browser tabs.
Why Buy It
- Very low power draw — ideal for a 24/7 server or NAS
- 4.1 GHz clock speed feels snappy for single tasks
- Integrated UHD 610 graphics work without a dedicated GPU
The Limitation
- Only 2 cores — struggles with multitasking and modern apps
- 4 MB cache is small, slowing down repeated data access
Great for: a basic server, a NAS box, or a single-task machine where power efficiency matters more than multitasking speed.
pass on it if: you plan to use this as a daily desktop PC — even the Core i3-9100 handles multitasking noticeably better.
Understanding the Specs
Cores, Threads, and Cache
A core is the part of the CPU that actually does the work — like having one worker. A thread is a virtual lane that lets one core handle two tasks at once. More threads mean the CPU can juggle more apps smoothly. Cache (measured in MB) is a fast scratchpad where the CPU stores data it uses often. Bigger cache keeps apps feeling responsive because the CPU does not have to wait for the main RAM as often.
Integrated Graphics vs Discrete GPU
A processor “with graphics” (like Intel UHD or AMD Radeon) lets you plug a monitor into the motherboard and get a display. This is fine for web browsing, streaming, and office work. A discrete GPU is a separate card you plug into a slot on the motherboard. It costs extra ( and up) but delivers the graphics power needed for modern games and video editing. If you only do basic tasks, save money with integrated graphics.
