DEEP-DIVE ANALYSIS
GENERATED BY THE ENGINEPairing the AMD Ryzen 7 8700G (72/100 on our gaming index) with the NVIDIA RTX 2080 Ti (31/100) 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.
Straight answer: aim for 1080p
The RTX 2080 Ti sets the limit at both ends of the range: a ~9% GPU bottleneck at 1080p that widens to ~62% at 4K. One number decides the purchase: 1080p is the most demanding of the standard 16:9 sizes that still sustains 69 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.
As you climb from 1080p to 4K, the load shifts from the processor toward the graphics card: every extra pixel lands on the RTX 2080 Ti. Here, efficiency moves from 91% at 1080p to 38% at 4K — which shows the part the frame rate depends on at each end.
Down to real numbers: In esports titles like Valorant this pair flies — around 603 FPS at 1080p, plenty for a high-refresh monitor. At the other end, a demanding AAA like Alan Wake 2 drops to ~15 FPS at 4K, which is where the RTX 2080 Ti's ceiling really shows. Overall, expect about 69 FPS average in AAA games at 1080p and around 30 FPS at 4K.
[CPU] Ryzen 7 8700G
The Ryzen 7 8700G scores 72/100 on this model's gaming scale, with 8 cores and 16 threads. In this pairing its job is to serve frames fast enough to never leave the graphics card waiting.
[GPU] RTX 2080 Ti
The RTX 2080 Ti (31/100 on the model's gaming scale) supplies the raster muscle of the build. Its 11 GB of GDDR6 set how far it can go on resolution and texture quality before video memory runs short.
Beyond the FPS: The processor is considerably newer than the graphics card (6 years), so you have plenty of headroom to drop in a stronger GPU later. You're combining an AMD platform with an NVIDIA GPU — a perfectly valid mix that imposes no penalty.
WHAT TO CHANGE, AND WHAT IT COSTS
At 1440p the RTX 2080 Ti sets the frame rate, and the Ryzen 7 8700G can drive a faster card. The cheapest card that clears our bar for a recommendation (at least 25% more frames) is the AMD RX 7800 XT: about 26% more in this model, with this processor and 16 GB. This processor keeps up with cards up to the NVIDIA RTX 5070 Ti; anything between the two is an upgrade that gets used, and beyond that card the processor becomes the limit.
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.

ESTIMATED FPS BY GAME
1920x1080SYSTEM DIAGNOSTICS
POWER · VRAM & PCIe · RAMPOWER ESTIMATION
The Ryzen 7 8700G (65W) and RTX 2080 Ti (250W) 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 RTX 2080 Ti's memory bus (352-bit) and bandwidth (616 GB/s) describe its own video memory, meaning how fast the card reads its 11 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 1080p, 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 7 8700G bottleneck the NVIDIA RTX 2080 Ti?
The RTX 2080 Ti sets the limit at both ends of the range: a ~9% GPU bottleneck at 1080p that widens to ~62% at 4K. Overall, the GPU is the limit at high resolution, with 56% average efficiency across the 12 resolutions our model tests. The resolution we would target with this pair is 1080p, where AAA games average 69 FPS.
How many FPS do the Ryzen 7 8700G and RTX 2080 Ti get at 1080p?
At 1080p this combination averages about 69 FPS in AAA games and around 354 FPS in esports titles. In Valorant we estimate up to 603 FPS.
Is this pairing good for 4K gaming?
Playable rather than smooth: about 30 FPS on average in AAA titles at 4K, with the RTX 2080 Ti 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 7 8700G and RTX 2080 Ti?
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 RTX 2080 Ti's 11 GB of VRAM enough?
11 GB covers all 11 tracked games at 1440p in the model; at 4K, 4 of them would need more, which costs frames or texture quality in those titles.
