If you want to build a super Budget PC that can genuinely handle gaming without ever needing to buy a discrete GPU, you need an AMD APU. Traditional desktop CPUs from Intel or standard AMD Ryzen chips only have basic integrated graphics meant for displaying the desktop and streaming video, but the AMD processors mentioned in this list are built specifically for gaming.
Here is the definitive list of the best Budget APUs for DDR4 platforms. No GPU needed, just a CPU for gaming.
The Best Budget APU
AMD Ryzen 5 3400G
The AMD Ryzen 5 3400G was released in mid 2019 and immediately became a legend for ultra budget PC builders. It earned its title as the best pre 2020 APU because it maximized what integrated graphics could do on the AM4 platform, blurring the line between integrated setups and entry level graphics cards.
Why the APU is S-Tier Choice For Budget Builds
- The Ultimate Cheap Used Component: On the used market, the Ryzen 5 3400G can often be found for incredibly low prices. It uses the highly accessible AM4 socket platform, meaning you can pair it with ultra affordable older motherboards (like an A320M or B450M) to build an entire Gaming PC for a fraction of the cost of a modern AM5 build.
- Upgradability Built In: Choosing the 3400G gives you a viable upgrade path. You can start a build with no graphics card, and then down the line, simply drop a dedicated GPU into the same motherboard when your budget allows.
- Savior of Modern Gaming: AMD FSR: The primary reason the 3400G can survive modern games is AMD FidelityFX Super Resolution (FSR). Because the integrated Vega 11 graphics architecture fully supports FSR spatial and temporal upscaling, you can run demanding modern games at a lower internal resolution (like 720p) and let FSR intelligently upscale it to a 1080p display. This feature provides a significant boost to frame rates, keeping modern titles in a playable state.

AMD Ryzen 5 2400G
The AMD Ryzen 5 2400G is considered an S-Tier choice for ultra budget modern gaming builds. While the 3400G is slightly newer, the 2400G is frequently labeled the true hero of budget gaming because of its massive price to performance ratio on the used market.
Why the Ryzen 5 2400G is S-Tier for Budget Builders
- The Same Elite Graphics Block: Even though it is older than the 3400G, the 2400G features the exact same Radeon RX Vega 11 integrated graphics with 11 Compute Units (704 stream processors). It delivers roughly 90-95% of the 3400G’s gaming performance but can often be bought used for significantly less money.
- Hyper-Threading Stability (4 Cores / 8 Threads): Cheaper alternatives from its era (like the Ryzen 3 2200G or 3200G) lack hyper-threading. The 2400G’s 8 threads prevent modern Windows background tasks and game audio/physics engines from locking up your CPU.
- The Cheapest Playable PC Foundation: You can buy a used 2400G, pair it with a dirt cheap AM4 motherboard (like an A320 or B450), and use a basic power supply since the whole chip only draws 65 watts. It allows you to build an entire functional computer for the price of a mid-range graphics card alone.
- Excellent Overclocking Potential: The 2400G features an completely unlocked multiplier. With basic tuning in the motherboard BIOS, you can easily push the Vega 11 graphics clock from its stock 1250MHz up closer to 1500MHz, matching the 3400G‘s performance for free.

AMD Ryzen 3 3200G
The AMD Ryzen 3 3200G is considered an S-Tier choice for ultra budget modern gaming builds. While the Ryzen 5 variants (2400G and 3400G) hold a slight advantage with hyper threading, the 3200G dominates the extreme budget category. It allows you to build a functional, playable PC for less money than 2400G and 3400G.
Why the Ryzen 3 3200G is S-Tier for Tight Budgets
- The Ultimate Value Entry Point: On the used marketplace, a standalone 3200G can frequently be purchased for incredibly cheap prices. This makes it significantly less expensive than the Ryzen 5 chips while providing about 85% of their gaming performance.
- Radeon Vega 8 Graphics: It features 8 Graphic Compute Units running at an optimized 1250MHz. Compared to any Intel processor from the same era, this graphics architecture completely outclasses Intel’s integrated options.
- Zen+ Architecture Improvements: Built on a 12nm process node, it provides superior memory compatibility and memory controller stability compared to older 14nm chips. This is vital because high-speed RAM directly impacts the speed of your integrated graphics.
- Low Power & Thermals: With a 65W TDP, it can comfortably run on basic, inexpensive motherboards (like an A320M or B450M) using its bundled Wraith Stealth cooler, completely removing the need to buy extra cooling gear.

AMD Ryzen 3 2200G
The AMD Ryzen 3 2200G is considered the absolute rock bottom S-Tier champion for extreme tight-budget builds. While the 3200G and the Ryzen 5 chips offer slightly higher processing limits, the 2200G holds a legendary status because it is routinely the cheapest usable chip you can acquire on the second hand market that avoids the need for a discrete GPU.
Why the Ryzen 3 2200G is S-Tier for Dirt-Cheap Gaming
- Radeon Vega 8 Architecture: It packs 8 Graphic Compute Units running at 1100MHz. While clocked lower than the 3200G out of the box, it features the exact same core graphical infrastructure, which completely crushes Intel’s integrated options from the same timeframe.
- Insane Overclocking Margins: The 2200G is fully unlocked. Builders quickly discovered that its Vega 8 graphics engine can easily be overclocked from 1100MHz up to 1500MHz or higher using basic motherboard adjustments, practically closing the performance gap with the newer 3200G for zero added cost.
- Ultra-Inexpensive Eco-System: You can slot this chip into early AM4 motherboards that go for very cheap on the used market. It runs cool on its bundled Wraith Stealth cooler, requiring minimal power.

Important Tips for an iGPU Only Build
Because an integrated GPU does not have its own dedicated VRAM, it shares your system’s RAM to handle game graphics. To get performance that makes you forget about buying a separate graphics card, ensure your build uses:
DDR4 3200MHz (CL16)
While AMD officially rates the memory controller on these chips to handle up to 2933MHz out of the box, 3200MHz is universally recognized as the performance sweet spot for these architectures.
- The Performance Gain: Moving from basic 2400MHz memory to 3200MHz scales gaming framerates up by a massive 10% to 15%.
- The Reason: The Vega 8 and Vega 11 graphics engines are constantly starved for memory bandwidth. Pushing the memory clock to 3200MHz allows data to feed into the graphics clusters significantly faster.
- Low Latency: Aim for a CL16 timing profile. Avoid high latency JEDEC kits (like CL22 or CL24), as games are highly sensitive to latency delays.
Dual-channel configuration
If you install a single 16GB stick of RAM instead of two 8GB sticks, you cut the data highway path in half. Running single channel memory drops your gaming FPS by roughly 40-45%. You must always ensure you occupy two DIMM slots to trigger Dual Channel memory bandwidth.
Final Thoughts
While the Ryzen 3 2200G and 3200G stand as the undisputed champions of dirt cheap, entry level esports and emulation, stepping up to the Ryzen 5 2400G or 3400G rewards you with vital hyper threading (4 cores/8 threads) and the superior power of Radeon Vega 11 graphics, which provides a much safer buffer for modern titles. No matter which of these budget legends you choose, their real world gaming performance is entirely tethered to your system memory.
