AMD Radeon RX 6950 XT vs NVIDIA GeForce RTX 5070 Ti Comparison

AMD Radeon RX 6950 XT and NVIDIA GeForce RTX 5070 Ti represent two distinct generations of GPU design, and the benchmark data reveals a clear generational shift in performance. The RTX 5070 Ti wins 9 out of 10 head-to-head tests, with the RX 6950 XT managing only a single tie. This comparison pits an end-of-life RDNA 2.0 flagship against an active Blackwell 2.0 release, and the numbers show the newer card holds a commanding lead in most workloads, though the older AMD card still has a few notable bright spots in its profile.

Head-to-Head Benchmarks

The most dramatic gap appears in the modern DirectX 12 workload of 3DMark Steel Nomad. The RTX 5070 Ti scores 6604, which is 35.9% ahead of the RX 6950 XT's 4235. This is the largest delta in the entire comparison and suggests the Blackwell architecture scales far better in current-generation rendering pipelines. The gap narrows considerably in Geekbench OpenCL, where the RTX 5070 Ti leads by only 3% (212363 vs 205998), indicating the AMD card remains competitive in compute-oriented OpenCL tasks.

Vulkan performance tells a different story, with the RTX 5070 Ti posting 225122 against the RX 6950 XT's 165212, a 26.6% advantage. This substantial margin in Vulkan suggests NVIDIA's driver and hardware implementation handles lower-level API calls more efficiently. The PassMark suite shows consistent but smaller NVIDIA wins: DirectX 10 (192 vs 164, a 14.6% edge), DirectX 12 (127 vs 114, a 10.2% edge), and DirectX 9 (351 vs 303, a 13.7% edge). The DirectX 11 test is the sole tie at 300 points each, a legacy API where neither card pulls ahead.

The compute-heavy PassMark GPU Compute test reveals another wide gap, with the RTX 5070 Ti scoring 20203 versus 14199 for the RX 6950 XT, a 29.7% difference. The RTX 5070 Ti also wins the 2D graphics test by 20.2% (1332 vs 1063), and the overall PassMark G3D score favors NVIDIA by 14.9% (32974 vs 28070). Interestingly, the average benchmark scores flip this narrative, with the RX 6950 XT averaging 58392 compared to the RTX 5070 Ti's 49957, though this average is skewed by the AMD card's inclusion of a Geekbench Metal score (222653) that the NVIDIA card lacks. The percentile rankings are close, with the RX 6950 XT at 88th percentile and the RTX 5070 Ti at 86th, suggesting both are high-end performers in the broader GPU landscape.

Architecture Differences

The architectural divide here is generational. The RX 6950 XT uses the Navi 21 chip built on RDNA 2.0 at TSMC's 7 nm process, while the RTX 5070 Ti employs the GB203 chip on Blackwell 2.0 at 5 nm. This process shrink enables a massive transistor density increase: the RTX 5070 Ti packs 45,600 million transistors on a 378 mm² die (120.6M per mm²), versus 26,800 million on the RX 6950 XT's 520 mm² die (51.5M per mm²). The NVIDIA chip is smaller yet denser, highlighting the efficiency of the newer node.

Shader configuration differs significantly. The RTX 5070 Ti has 8960 shading units, 280 TMUs, and 96 ROPs, while the RX 6950 XT has 5120 shading units, 320 TMUs, and 128 ROPs. Despite fewer TMUs and ROPs, the RTX 5070 Ti achieves higher throughput in most tests, indicating that raw unit counts matter less than architectural efficiency. The RTX 5070 Ti also includes 280 tensor cores, a feature entirely absent from the RX 6950 XT's specification sheet, which likely explains its superior compute performance.

Clock speeds favor the RTX 5070 Ti, with a base of 2295 MHz and boost of 2452 MHz versus the RX 6950 XT's 1860 MHz base and 2310 MHz boost. The NVIDIA card also has a higher memory clock at 1750 MHz (28 Gbps effective) compared to the AMD card's 2250 MHz (18 Gbps effective). Both cards use a 256-bit memory bus and 16 GB of VRAM, but the RTX 5070 Ti's GDDR7 memory delivers 896.0 GB/s bandwidth versus 576.0 GB/s for the RX 6950 XT's GDDR6. The FP32 compute rating also shows a clear hierarchy: 43.94 TFLOPS for the RTX 5070 Ti versus 23.65 TFLOPS for the RX 6950 XT, with the RTX 5070 Ti maintaining FP16 at the same 43.94 TFLOPS (1:1) while the RX 6950 XT reaches 47.31 TFLOPS (2:1).

Where Each One Wins

The RTX 5070 Ti is the clear winner in modern gaming and compute scenarios. Its 35.9% lead in 3DMark Steel Nomad suggests it handles DirectX 12 Ultimate titles with far greater ease, making it the better choice for current AAA games. The 26.6% Vulkan advantage also positions it well for games that leverage that API, and the 29.7% compute lead indicates superior performance in GPU-accelerated workloads like rendering or scientific calculations. The 20.2% win in PassMark G2D also hints at better desktop and 2D application responsiveness.

The RX 6950 XT's only victory is a tie in PassMark DirectX 11 at 300 points, which means in legacy DirectX 11 games, the two cards perform identically. This is notable because it suggests the older architecture hasn't lost ground in that API, and for users with a library of older titles, the RX 6950 XT remains perfectly serviceable. The RX 6950 XT also has a higher pixel rate (295.7 GPixel/s vs 235.4 GPixel/s) and texture rate (739.2 GTexel/s vs 686.6 GTexel/s), though these theoretical advantages don't translate into benchmark wins. Its higher ROP count (128 vs 96) and TMU count (320 vs 280) give it raw fill-rate advantages that the RTX 5070 Ti overcomes through architectural efficiency.

Specification Differences

The two cards differ across nearly every specification category. The process node shifts from 7 nm to 5 nm, and the transistor count jumps from 26,800 million to 45,600 million. Die size shrinks from 520 mm² to 378 mm². Base clock rises from 1860 MHz to 2295 MHz, and boost clock from 2310 MHz to 2452 MHz. Memory type changes from GDDR6 to GDDR7, with bandwidth increasing from 576.0 GB/s to 896.0 GB/s. Shading units increase from 5120 to 8960, while TMUs decrease from 320 to 280 and ROPs from 128 to 96.

The RTX 5070 Ti adds 280 tensor cores and 70 RT cores, while the RX 6950 XT has 80 RT cores. FP32 performance doubles from 23.65 TFLOPS to 43.94 TFLOPS. Power draw drops from 335 W to 300 W, and the card shrinks from triple-slot to dual-slot. Power connectors change from 2x 8-pin to 1x 16-pin, though both recommend a 700 W PSU. The bus interface advances from PCIe 4.0 x16 to PCIe 5.0 x16. Display outputs differ, with the RX 6950 XT offering 1x HDMI 2.1 and 2x DisplayPort 1.4a versus the RTX 5070 Ti's 1x HDMI 2.1b and 3x DisplayPort 2.1b. Physical dimensions also shift: the RX 6950 XT measures 267 mm x 120 mm x 50 mm, while the RTX 5070 Ti is larger at 304 mm x 137 mm x 48 mm. Production status moves from end-of-life to active, and release dates span from 2022-05-09 to 2025-02-19.
