RTX 5070 vs RX 9070 XT — Which GPU Should You Buy in 2026?

The RTX 5070 and RX 9070 XT are the two most talked-about mid-range to upper-mid GPUs in 2026 — and they target almost the same buyer. This guide compares every aspect so you can make a confident decision for your next custom gaming PC build in the UK.

Price and Availability in the UK

In the UK market as of mid-2026:

  • NVIDIA RTX 5070: Approximately £550–£620 for AIB cards (Asus, MSI, Gigabyte, Palit variants)
  • AMD RX 9070 XT: Approximately £480–£550 for AIB cards

The RX 9070 XT currently holds a meaningful price advantage of around £70–£80 in the UK. That's enough for a faster CPU, more RAM, or additional SSD storage in a custom build.

Raw Gaming Performance — 1080p

At 1080p, both cards are so fast that the limiting factor is almost always the CPU. Frame rates in competitive titles like CS2 and Valorant can exceed 400fps on both cards with a fast CPU. At 1080p, the GPU difference is irrelevant — spend less on GPU and more on CPU and RAM at this resolution.

Raw Gaming Performance — 1440p (The Real Battleground)

1440p is where these cards are designed to shine. In demanding titles at Ultra settings:

  • Cyberpunk 2077 (1440p Ultra, no RT): RTX 5070 ~115fps avg, RX 9070 XT ~105fps avg
  • Alan Wake 2 (1440p Ultra, no RT): RTX 5070 ~100fps, RX 9070 XT ~88fps
  • Forza Horizon 5 (1440p Ultra): RTX 5070 ~195fps, RX 9070 XT ~180fps
  • Call of Duty Warzone (1440p Ultra): RTX 5070 ~200fps, RX 9070 XT ~185fps
  • Baldur's Gate 3 (1440p Ultra): Both exceed 100fps — GPU-limited equally

The RTX 5070 leads by roughly 8–12% at 1440p in rasterisation performance. Both deliver an excellent experience — the question is whether that margin justifies the price difference.

4K Performance

Both cards are capable at 4K, but this is where their upscaling solutions become critical:

  • RTX 5070 (with DLSS 4 Quality mode): Excellent 4K experience. DLSS 4 Quality produces near-native quality with a significant performance boost — comfortable 70–90fps in demanding titles.
  • RX 9070 XT (with FSR 3.1 Quality mode): FSR 3.1 Quality is good but visibly slightly softer than DLSS 4. Performance similar to DLSS 4 Performance mode. Still a smooth 4K experience in most games.

For native 4K without upscaling, neither card is ideal — that's RTX 5080/5090 territory. But with upscaling enabled, both deliver good results.

Ray Tracing

NVIDIA has a significant RT hardware advantage, and this is one area where the RTX 5070 clearly wins:

  • In games with ray tracing enabled (Cyberpunk 2077, Metro Exodus Enhanced Edition), the RTX 5070 is typically 30–40% faster than the RX 9070 XT
  • For path-traced games, the gap is even larger — the RX 9070 XT struggles to maintain smooth frame rates with full path tracing at 1440p

If ray tracing is important to you and you regularly play RT-enabled titles, the RTX 5070 is the better choice.

DLSS 4 vs FSR 3.1

Both cards support Frame Generation (FG) — a technology that uses AI or compute to generate additional frames between rendered frames, boosting perceived frame rates significantly:

  • NVIDIA DLSS 4 (Transformer model): Uses dedicated tensor cores. Image quality is class-leading. DLSS 4 at Quality mode is nearly indistinguishable from native resolution. Multi Frame Generation can multiply frame rates by 2–4x in supported titles.
  • AMD FSR 3.1: Open-source, works on any GPU including NVIDIA. Spatial upscaling quality is good but slightly behind DLSS 4 at equivalent quality settings. Frame Generation is GPU-compute-based — works well but introduces slightly more latency than DLSS 4 FG.

VRAM — Does 12GB vs 16GB Matter?

The RTX 5070 features 12GB of GDDR7 VRAM. The RX 9070 XT has 16GB of GDDR6.

In 2026, 12GB is sufficient for the vast majority of 1440p gaming. However, a growing number of titles — particularly open-world games with high-resolution texture packs — push past 12GB at 4K Ultra. If you plan to game at 4K with maximum settings and texture mods, the RX 9070 XT's 16GB is a meaningful advantage. At 1440p, 12GB remains fine for the foreseeable future.

Power Efficiency

  • RTX 5070 TDP: ~250W — comfortable in an 850W system
  • RX 9070 XT TDP: ~220W — also fine in an 850W system

Both cards are efficient enough for standard builds. No PSU upgrade required for either at typical system configurations.

Which GPU Is Right for You?

  • Choose RTX 5070 if: You regularly play ray-traced games, you value DLSS 4 image quality, you want NVIDIA's ecosystem (NVENC for streaming, DLSS in more titles), or you game at 4K where the extra RT performance helps.
  • Choose RX 9070 XT if: You primarily game at 1440p in rasterisation titles, budget efficiency matters, you want more VRAM headroom for future games, or you prefer AMD's open ecosystem with FSR working across all hardware.
