AMD launched the RX 7600 XT in early 2025 as a refined version of the RX 7600, adding a substantially larger 16GB GDDR6 VRAM buffer to an otherwise familiar RDNA 3 architecture. The card sits in the sub-£350 bracket and targets players who want more VRAM headroom without stepping into RTX 4070 territory.
The result is a card with a specific, clear use case. Whether that use case matches yours will determine whether it is the right buy.
Specs
The RX 7600 XT uses the same Navi 33 die as the original RX 7600, with slightly higher clock speeds. The headline change is the memory: 16GB of GDDR6 on a 128-bit bus, double the VRAM of the standard 7600. The 128-bit bus is a constraint at higher resolutions, and it is worth understanding before buying.

Performance
At 1080p, the RX 7600 XT performs similarly to the RX 7600 in most scenarios, with the clock speed uplift providing a modest frame rate benefit. The VRAM advantage is largely theoretical at 1080p: very few titles push past 8GB at 1080p even on Ultra settings, and the 128-bit bus limits raw bandwidth.
At 1440p, the picture changes. The 16GB buffer provides meaningful headroom in VRAM-intensive workloads, particularly in titles that have received high-resolution texture packs or that push asset streaming hard. In these scenarios, the 7600 XT avoids the stuttering and performance degradation that can affect 8GB cards.
Rasterisation performance in modern titles sits roughly in line with the RTX 4060 and Intel Arc B580, with AMD’s typically strong DirectX 11 performance giving it an edge over the B580 in older titles.
FSR and Upscaling
AMD’s FidelityFX Super Resolution (FSR) support is broad: because FSR is an open standard that does not require AMD hardware, almost every game that supports upscaling supports FSR. At 1440p with FSR Quality mode, the 7600 XT produces clean output in most tested titles.
The RX 7600 XT also supports AMD’s Fluid Motion Frames (AFMF) for frame generation in supported titles, which can provide a noticeable smoothness improvement in games that do not have native frame generation support.
The 128-Bit Bus Question
The 128-bit memory bus is the card’s primary structural limitation. More memory bandwidth allows a GPU to move data faster between VRAM and the compute units. At 1080p this is rarely a bottleneck, but at 1440p in bandwidth-heavy workloads, the narrower bus can constrain performance relative to cards with wider buses at similar price points.
This means the 7600 XT’s 16GB is not the same as 16GB on a card with a 192-bit or 256-bit bus. The headline VRAM figure is real and useful, but the bandwidth to feed that memory is not unlimited.
Who It Is For
The RX 7600 XT makes most sense for a specific buyer: someone building a 1080p-primary system who anticipates playing titles with high VRAM demands, or a 1440p player who wants buffer room without spending RTX 4070 money. It also makes sense for anyone whose library is older DirectX 11 titles, where AMD’s driver maturity provides real-world benefits over Intel’s Arc offerings.
If you are choosing between the B580 and the 7600 XT at similar price points, the B580 has more VRAM bandwidth and better performance in newer DX12 titles. The 7600 XT has better older-game compatibility and broader upscaling game support via FSR.
Neither is wrong. The right answer depends on what you play.
Score: 7/10 - Good
