DEEP-DIVE ANALYSIS
GENERATED BY THE ENGINEThis page breaks down, number by number, what happens when you run an Intel Core i5-10600K alongside an Intel Arc B580. The processor scores 56/100 and the graphics card 22/100 in our model — the interesting part is how they split the workload at each resolution.
Straight answer: 1440p, at about 38 FPS in AAA
The Arc B580 sets the limit at both ends of the range: a ~8% GPU bottleneck at 1080p that widens to ~64% at 4K. No 16:9 size keeps this pair above 60 FPS in demanding titles. 1440p is the highest that stays playable, at roughly 38 FPS on average in AAA. Esports is a different story — around 236 FPS at 1080p.
As you climb from 1080p to 4K, the load shifts from the processor toward the graphics card: every extra pixel lands on the Arc B580. Here, efficiency moves from 92% at 1080p to 36% at 4K — which shows the part the frame rate depends on at each end.
In esports titles like Valorant this pair flies — around 388 FPS at 1080p, plenty for a high-refresh monitor. At the other end, a demanding AAA like Alan Wake 2 drops to ~10 FPS at 4K, which is where the Arc B580's ceiling really shows. Overall, expect about 54 FPS average in AAA games at 1080p and around 22 FPS at 4K.
[CPU] Core i5-10600K
On the CPU side: the Core i5-10600K rates 56/100 for gaming in this model and brings 6 cores and 12 threads. At lower resolutions it's the one setting the pace for the whole system.
[GPU] Arc B580
The Arc B580 scores 22/100 on this model's gaming scale. Its 12 GB of GDDR6 set how far it can go on resolution and texture quality before video memory runs short. It draws every pixel, so its weight grows the higher you push the resolution.
A detail that's easy to overlook: The graphics card is about 4 years newer than the processor, so watch that the Core i5-10600K doesn't fall short in the most CPU-dependent games. You're combining an Intel platform with an Intel GPU — a perfectly valid mix that imposes no penalty.
DO YOU NEED TO CHANGE ANYTHING?
At 1440p the Arc B580 sets the frame rate. No card in our catalogue clears the bar we use for a recommendation: at least 25% more frames while the Core i5-10600K still keeps it fully fed. The closest, the NVIDIA RTX 5090, adds about 81% in this model. So there is no card we would tell you to buy for this pairing.

ESTIMATED FPS BY GAME
1920x1080SYSTEM DIAGNOSTICS
POWER · VRAM & PCIe · RAMPOWER ESTIMATION
The Core i5-10600K (125W) and Arc B580 (190W) add up to roughly 315W under load. Adding 150W for the rest of the system gives 465W, and with a 30% transient margin, 650W is the safe figure.
VIDEO MEMORY AND PCIe
The Arc B580's memory bus (192-bit) and bandwidth (456 GB/s) describe its own video memory, meaning how fast the card reads its 12 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 Intel Core i5-10600K bottleneck the Intel Arc B580?
The Arc B580 sets the limit at both ends of the range: a ~8% GPU bottleneck at 1080p that widens to ~64% at 4K. Overall, the GPU is the limit at high resolution, with 53% average efficiency across the 12 resolutions our model tests. 1440p is the highest resolution that stays playable, at about 38 FPS on average in AAA titles.
How many FPS do the Core i5-10600K and Arc B580 get at 1080p?
At 1080p this combination averages about 54 FPS in AAA games and around 236 FPS in esports titles. In Valorant we estimate up to 388 FPS.
Is this pairing good for 4K gaming?
Not for AAA titles at native high settings: about 22 FPS on average at 4K. It would take upscaling, much lower settings or faster hardware.
What power supply do I need for the Core i5-10600K and Arc B580?
With an estimated combined draw of 315W across CPU and GPU, we recommend at least a 650W 80+ Gold supply (ideally ATX 3.0) to run with headroom.
Is the Arc B580's 12 GB of VRAM enough?
12 GB covers all 11 tracked games at 1440p in the model; at 4K, 3 of them would need more, which costs frames or texture quality in those titles.
