DEEP-DIVE ANALYSIS
GENERATED BY THE ENGINEPairing the AMD Ryzen 5 2600 (43/100 on our gaming index) with the AMD RX 9070 (48/100) raises one practical question: do they pull together, or does one hold the other back? We ran this exact combination across all supported resolutions to answer it with numbers rather than guesswork.
Quick take: 1440p is the resolution to target
At 1080p the Ryzen 5 2600 becomes the limiting part (~48% CPU bottleneck), whereas at 4K the RX 9070 is the limiting part (~12% GPU bottleneck). One number decides the purchase: 1440p is the most demanding of the standard 16:9 sizes that still sustains 68 FPS on average in AAA games, above the 60 FPS bar we treat as smooth. Step up a rung and the frame rate drops below that mark.
Think of resolution as a dial that splits the weight between CPU and GPU. Drop to 1080p and you wring out the RX 9070 while leaning harder on the Ryzen 5 2600; push to 4K and the opposite happens. Synergy here swings between 88% and 52% depending on where you sit.
In esports titles like Valorant this pair flies — around 245 FPS at 1080p, plenty for a high-refresh monitor. At the other end, a demanding AAA like Alan Wake 2 drops to ~26 FPS at 4K, which is where the RX 9070's ceiling really shows. Overall, expect about 76 FPS average in AAA games at 1080p and around 46 FPS at 4K.
[CPU] Ryzen 5 2600
The Ryzen 5 2600 (43/100 on the model's gaming scale) brings 6 cores and 12 threads and determines how many frames per second the system can prepare.
[GPU] RX 9070
The RX 9070 (48/100 on the model's gaming scale) supplies the raster muscle of the build. Its 16 GB of GDDR6 set how far it can go on resolution and texture quality before video memory runs short.
Beyond the FPS: The graphics card is about 7 years newer than the processor, so watch that the Ryzen 5 2600 doesn't fall short in the most CPU-dependent games. You're combining an AMD platform with an AMD GPU — a perfectly valid mix that imposes no penalty.
WHAT TO CHANGE, AND WHAT IT COSTS
At 1440p the Ryzen 5 2600 sets the frame rate and leaves part of the RX 9070 idle. The cheapest processor in our catalogue that keeps the card fully fed and clears our bar (at least 10% more frames) is the AMD Ryzen 5 5600: about 46% more in this model, with this card and 16 GB.
The gain is the model's estimate at 2560x1440 with 16 GB, not a measurement of your PC, and prices change: check them at the retailer before deciding.

BOTTLENECK BY RESOLUTION
SYNERGY · AVERAGE FPSYour CPU (Ryzen 5 2600) cannot feed the RX 9070 fast enough at 1920x1080. The GPU sits waiting for frames, causing stutter and noticeable drops. A CPU upgrade is the highest-impact change you can make.

Your CPU (Ryzen 5 2600) introduces a slight limitation at 3440x1440 (Ultrawide 21:9). Real-world impact is small and both components work well together.
Your CPU (Ryzen 5 2600) and GPU (RX 9070) are an exceptionally balanced match for gaming at 5120x1440 (Super Ultrawide 32:9). No realistic component swap would meaningfully improve this build.
Your GPU (RX 9070) is a slight limiting factor at 4K, with limited real-world impact. Most titles will run smoothly.
ESTIMATED FPS BY GAME
1920x1080SYSTEM DIAGNOSTICS
POWER · VRAM & PCIe · RAMPOWER ESTIMATION
The Ryzen 5 2600 (65W) and RX 9070 (220W) add up to roughly 285W under load. Adding 150W for the rest of the system gives 435W, and with a 30% transient margin, 600W is the safe figure.
VIDEO MEMORY AND PCIe
The RX 9070's memory bus (256-bit) and bandwidth (512 GB/s) describe its own video memory, meaning how fast the card reads its 16 GB of GDDR6, not the PCIe link to the processor. The PCIe link depends on the card, the processor and the motherboard slot together; our catalogue does not record PCIe generation or lane count, so the model does not estimate it. It matters most for cards with an eight-lane interface in older PCIe 3.0 boards: check the card's and the board's specifications.
SYSTEM MEMORY
This page assumes 16 GB in dual channel. At 1440p, the resolution recommended above, that meets the model's capacity target of 16 GB (enough for three in four of the games it covers), so more capacity would add little or nothing there. The target stays at 16 GB even at 4K, so a larger kit is for heavy multitasking or mods, not for these games. Memory speed and a second channel act on the processor's ceiling instead: they matter in the games the CPU limits, by an amount that depends on the game, and the calculator lets you enter your own kit.
HOW THIS PAGE IS CALCULATED
ENGINE v2026.08 · 2026-09-11CALCULATED, NOT WRITTEN
Every figure and every sentence comes from the same deterministic engine, driven by the catalogue specifications. That is what makes it reproducible: with the same engine version (2026.08) and the same catalogue, the same pairing always gives the same result. When either changes, the version and date above change with it, and the changelog says why.
WHERE THE DATA COMES FROM
Specifications come from the official AMD, Intel and NVIDIA datasheets together with PassMark and TechPowerUp. The gaming indices are calibrated against frame rates published by review outlets (TechPowerUp, TechSpot / Hardware Unboxed, Tom's Hardware, Gamers Nexus, Digital Foundry) rather than synthetic scores. That data is compiled, not measured here: this site runs no test bench of its own.
STATED LIMITS
Figures estimate native raster performance at high/ultra quality, with no ray tracing, upscaling or frame generation. We do not yet publish an externally validated error margin — the accuracy page states exactly where that stands.

FREQUENTLY ASKED QUESTIONS
5Does the AMD Ryzen 5 2600 bottleneck the AMD RX 9070?
At 1080p the Ryzen 5 2600 becomes the limiting part (~48% CPU bottleneck), whereas at 4K the RX 9070 is the limiting part (~12% GPU bottleneck). Overall, the GPU is the limit at high resolution, with 72% average efficiency across the 12 resolutions our model tests. The resolution we would target with this pair is 1440p, where AAA games average 68 FPS.
How many FPS do the Ryzen 5 2600 and RX 9070 get at 1080p?
At 1080p this combination averages about 76 FPS in AAA games and around 164 FPS in esports titles. In Valorant we estimate up to 245 FPS.
Is this pairing good for 4K gaming?
Playable rather than smooth: about 46 FPS on average in AAA titles at 4K, with the RX 9070 setting the limit. Upscaling (DLSS, FSR or XeSS) or lower settings are the usual way to reach 60 FPS.
What power supply do I need for the Ryzen 5 2600 and RX 9070?
With an estimated combined draw of 285W across CPU and GPU, we recommend at least a 600W 80+ Gold supply (ideally ATX 3.0) to run with headroom.
Is the RX 9070's 16 GB of VRAM enough?
In the model, 16 GB covers all 11 games it tracks even at 4K with high textures, so video memory is not the constraint for this pairing.
