What Is the AMD Radeon RX 7800 XT?
The AMD Radeon RX 7800 XT is a mid-range graphics card built on the RDNA 3 architecture, using the Navi 32 die. It launched in September 2023 at an MSRP of £/$449, though street prices have since settled between £380 and £420.
This card is designed to be AMD's primary weapon for high-refresh-rate 1440p gaming. It slots in above the RX 7700 XT and below the RX 7900 GRE in the current stack.
It directly succeeds the RX 6800 XT, though the generational leap is more nuanced than a simple speed bump. RDNA 3 introduces a chiplet design (GCD plus MCDs) and improved ray tracing hardware, but the RX 7800 XT uses a smaller die than its predecessor, with fewer compute units.
In practice, it trades blows with the RX 6800 XT in rasterisation while offering better ray tracing efficiency and a lower TDP of 263W. The 16GB of GDDR6 VRAM is a deliberate move: AMD is betting that memory capacity will matter more than raw bandwidth in the coming years, and at this price point, it's a clear differentiator against Nvidia's competing RTX 4070, which ships with only 12GB.
1440p Gaming Performance
At 1440p, the RX 7800 XT is exactly where AMD wants it to be. It delivers between 80 and 100 fps in demanding titles like Cyberpunk 2077 (without ray tracing) and Hogwarts Legacy, with lighter competitive shooters like Call of Duty: Modern Warfare III pushing well past 120 fps.
The card is comfortable at high and ultra settings, making it a strong choice for anyone with a 1440p 144Hz or 165Hz monitor. It generally matches or slightly edges the RTX 4070 in pure rasterisation, particularly in games that favour AMD's architecture, such as Far Cry 6 and Assassin's Creed Mirage.
The 16GB VRAM Advantage
The 16GB VRAM buffer is the headline advantage here. In Alan Wake 2 at 1440p with high textures, the RTX 4070's 12GB can become a bottleneck, causing stutter or texture pop-in during extended sessions. The RX 7800 XT handles this without breaking a sweat.
For modern titles that are increasingly VRAM-hungry, this extra headroom means you can keep texture quality at ultra without worrying about hitting a memory ceiling. This makes the RX 7800 XT the more future-proof option for 1440p gaming, especially if you plan to keep the card for three to four years.
4K and Ray Tracing: Where It Falls Short
4K gaming is a stretch for the RX 7800 XT, and reviews advise against it unless you're prepared to drop settings significantly. In Cyberpunk 2077 at native 4K, you're looking at 40-50 fps on high settings, which is playable but not smooth.
Upscaling via FSR 3 helps, but the image quality hit is noticeable compared to native or DLSS. The RTX 4070, with its better upscaling and slightly higher raw performance, is the stronger 4K card here, but neither is truly comfortable at this resolution for demanding titles.
Ray Tracing Weakness
Ray tracing performance is the RX 7800 XT's most obvious weakness. AMD has improved ray tracing throughput over RDNA 2, but it still trails Nvidia's RTX 4070 by a significant margin.
- In Cyberpunk 2077 with ray tracing on medium at 1440p: the RX 7800 XT delivers around 50-55 fps, while the RTX 4070 manages 65-70 fps.
- In Alan Wake 2: the gap widens further, with the AMD card struggling to maintain 40 fps with ray tracing enabled.
If you care about ray tracing, the RTX 4070 is the clear winner, and reviews argue that even the RX 7900 GRE doesn't close this gap enough to matter. The RX 7800 XT is best treated as a rasterisation-first card, with ray tracing as a bonus feature for lighter implementations.
FSR 3 and AMD Software
AMD's FSR 3 upscaling with frame generation is supported on the RX 7800 XT. In titles like Forspoken and Immortals of Aveum, it can boost frame rates by 60-80%.
The technology works reasonably well, though it's not as polished as Nvidia's DLSS 3. There is more ghosting and occasional artefacts in fast-moving scenes, and the base image quality of FSR 3 at Quality mode is softer than DLSS at the same setting.
The bigger issue is game support: FSR 3 is available in far fewer titles than DLSS 3, and adoption has been slow. AMD's open-source approach means developers can implement it more easily, but in practice, the library is thin.
Radeon Software Suite
The Radeon Software suite remains one of the best in the business. It's clean, responsive, and offers granular controls for tuning, overclocking, and recording. Driver stability has been solid, with no crashes or quirks across a range of games.
AMD also includes features like Radeon Anti-Lag and Radeon Boost, which can reduce input latency in competitive titles. However, Nvidia's DLSS 3 frame generation feels more mature and has broader support, so if upscaling quality matters to you, the RTX 4070 holds an edge.
Thermals, Power, and Noise
The RX 7800 XT has a TDP of 263W, which is reasonable for its performance class. On the Sapphire Pulse and ASUS Dual models, temperatures peak at around 75°C under load, with fan noise staying below 40 dBA in a closed case.
The card runs cooler and quieter than the RX 6800 XT, which could hit 85°C and sound like a hairdryer. Most AIB partners have done a good job with cooling, and the dual-fan designs are compact enough to fit in smaller cases.
Power draw is roughly on par with the RTX 4070, though Nvidia's card is more efficient at idle. A 650W PSU is recommended as a minimum, though 750W gives you headroom for overclocking.
The RX 7800 XT vs RTX 4070: Which Should You Buy?
At similar street prices (around £400-420 for the RX 7800 XT, £450-480 for the RTX 4070), the choice comes down to priorities. The RX 7800 XT wins on VRAM (16GB vs 12GB) and raw rasterisation performance, making it the better pick for 1440p gaming without ray tracing.
The RTX 4070 counters with superior ray tracing, better upscaling via DLSS 3, and lower power draw at idle. If you play a lot of Cyberpunk 2077 or Alan Wake 2 with ray tracing enabled, the Nvidia card is worth the extra £50-60.
| Feature | RX 7800 XT | RTX 4070 |
|---|---|---|
| VRAM | 16GB GDDR6 | 12GB GDDR6X |
| Rasterisation | Stronger at 1440p | Slightly behind |
| Ray tracing | Weaker, 50-55 fps in Cyberpunk at 1440p | Stronger, 65-70 fps in Cyberpunk at 1440p |
| Upscaling | FSR 3, less polished | DLSS 3, more mature |
| Typical street price | £400-420 | £450-480 |
If you're focused on pure frame rates at 1440p and want to avoid VRAM limitations in future titles, the AMD card is the smarter buy. The RTX 4070 also has a slight edge in productivity tasks like Blender rendering, thanks to CUDA and OptiX.
For pure gaming, the RX 7800 XT offers better value, especially if you can find it under £400. The RX 7900 GRE sits above both but costs more, so it's not a direct competitor here.
Verdict
The AMD Radeon RX 7800 XT is the best value 1440p GPU on the market today, provided you don't care deeply about ray tracing.
The RX 7800 XT's 16GB VRAM, strong rasterisation performance, and competitive price make it an easy recommendation for anyone building a mid-range gaming PC. It scores 8.4/10 on RTINGS, and it's the card most gamers should buy if they want high frame rates at 1440p without breaking the bank.
However, it's not for everyone. If ray tracing is a priority, or if you want the best upscaling technology available, the RTX 4070 is a better choice despite its smaller VRAM buffer.
The RX 7800 XT is a focused product that excels in its lane. It's not trying to be a 4K ray tracing monster; it's trying to be the best 1440p rasterisation card for the money, and in that regard, it succeeds admirably.
Buy it if you want raw frames, skip it if you want ray tracing bells and whistles.
