AMD Radeon RX 7800 XT vs NVIDIA GeForce RTX 5070 Ti Mobile Comparison

Where Each One Wins

The recorded benchmark data splits the two GPUs almost evenly, with the AMD Radeon RX 7800 XT taking 5 of the 9 head-to-head tests and the NVIDIA GeForce RTX 5070 Ti Mobile winning 4. The split is not arbitrary, it follows a clear functional pattern. The AMD card dominates in compute-oriented and legacy DirectX workloads, while the NVIDIA mobile part wins decisively in modern API compute tests and the newer DirectX 12 path.

The RX 7800 XT holds its ground in the Passmark suite. It wins DirectX 11 by 5.1%, DirectX 9 by 17.4%, and the G2D test by 20%. Its largest margin comes in GPU compute, where it leads by 33.4%. The G3D test is essentially a tie, with the AMD card ahead by only 0.7%. These results point to a desktop card with strong raw throughput in traditional rendering and compute tasks.

The RTX 5070 Ti Mobile, despite being a laptop part with a 60 W TDP, wins the two most demanding cross-platform tests. In Geekbench OpenCL it scores 143870 against 18290, a 87.3% advantage. In Geekbench Vulkan it scores 139213 against 54228, a 61% advantage. It also wins DirectX 10 by 19.9% and DirectX 12 by 8.8%. The pattern is consistent: NVIDIA's newer architecture excels in modern low-level APIs and compute-heavy synthetic loads, while AMD's older RDNA 3 design retains advantages in legacy API paths and specific compute patterns.

The percentile data reinforces the NVIDIA card's overall standing. The RTX 5070 Ti Mobile sits at the 80th percentile among all GPUs, while the RX 7800 XT sits at the 51st. The average benchmark score tells a similar story: the NVIDIA part averages 35435, the AMD part averages 11627. The nearest rival data for each card shows how they compare within their own performance strata. The RX 7800 XT sits within 1.8% of the AMD Radeon RX 6500 XT and 1.3% of the NVIDIA Tesla K20c. The RTX 5070 Ti Mobile sits within 2.4% of the NVIDIA T1000 and 2.1% of the NVIDIA A2.

Architecture Differences

The two GPUs come from different architectural generations and design philosophies. The RX 7800 XT uses the Navi 32 chip on RDNA 3.0, with the codename Wheat Nas, part of the Navi III (RX 7000) generation. The RTX 5070 Ti Mobile uses the GB205 chip on Blackwell 2.0, part of the GeForce 50 Mobile generation. Both are fabricated on a 5 nm process at TSMC, but the transistor counts differ substantially. The AMD chip packs 28,100 million transistors on a 346 mm² die, giving a transistor density of 81.2M per mm². The NVIDIA chip packs 31,100 million transistors on a smaller 263 mm² die, yielding a much higher density of 118.3M per mm².

The compute resources are arranged differently. The RX 7800 XT has 3840 shading units, 240 TMUs, and 96 ROPs. The RTX 5070 Ti Mobile has 5888 shading units, 184 TMUs, and 80 ROPs. Despite having more shading units, the NVIDIA card reports lower FP32 throughput at 17.04 TFLOPS versus 37.32 TFLOPS for AMD. This reflects the different clock behavior. The AMD card boosts to 2430 MHz with a base of 1295 MHz and a game clock of 2124 MHz. The NVIDIA card boosts to only 1447 MHz with a base of 847 MHz.

The memory subsystems also diverge. The RX 7800 XT uses 16 GB of GDDR6 on a 256-bit bus, delivering 624.1 GB/s of bandwidth. The RTX 5070 Ti Mobile uses 12 GB of GDDR7 on a 192-bit bus, delivering 672.0 GB/s. The newer GDDR7 memory runs at 1750 MHz with 28 Gbps effective, while the GDDR6 runs at 2438 MHz with 19.5 Gbps effective. The NVIDIA card achieves higher bandwidth despite a narrower bus and fewer memory modules.

Feature sets differ in predictable ways. The RX 7800 XT has 60 RT cores and no tensor cores. The RTX 5070 Ti Mobile has 46 RT cores and 184 tensor cores, reflecting NVIDIA's investment in AI-accelerated workloads. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD card uses PCIe 4.0 x16, the NVIDIA card uses PCIe 5.0 x16. Power delivery is completely different: the RX 7800 XT draws 263 W with dual 8-pin connectors and a 600 W suggested PSU, while the RTX 5070 Ti Mobile draws only 60 W with no power connectors, being an integrated graphics processor for laptops.

Head-to-Head Benchmarks

The largest single delta in the entire comparison appears in Geekbench OpenCL. The RTX 5070 Ti Mobile scores 143870 against the RX 7800 XT's 18290, a 87.3% gap. This is not a narrow margin, it is a dominant victory for the NVIDIA part in a compute-heavy synthetic test. The Geekbench Vulkan result follows a similar shape: NVIDIA scores 139213, AMD scores 54228, a 61% advantage. These two tests alone account for most of the NVIDIA card's overall score advantage.

The DirectX legacy tests tell the opposite story. In DirectX 9, the RX 7800 XT scores 304 against 259, a 17.4% win. In DirectX 11, AMD scores 249 against 237, a 5.1% win. The G2D test shows AMD ahead by 20%, with scores of 1177 versus 981. The G3D test is nearly flat, with AMD ahead by 0.7% (24176 versus 24004). These results suggest that the older RDNA 3 architecture retains strong performance in legacy API paths, while the newer Blackwell architecture does not prioritize those paths.

The GPU compute test favors AMD substantially. The RX 7800 XT scores 13473 against 10101, a 33.4% margin. This is notable because the OpenCL result went the other way so heavily. The Passmark GPU compute test likely uses a different workload profile than Geekbench OpenCL, and the AMD card's higher FP32 throughput (37.32 TFLOPS) appears to pay off in that specific benchmark. The DirectX 10 and DirectX 12 tests both go to NVIDIA, with margins of 19.9% and 8.8% respectively. The DirectX 12 score of 102 versus 93 is a modest win, but it aligns with the newer architecture's strength in modern API paths.

The average benchmark scores put the comparison in context. The RTX 5070 Ti Mobile averages 35435, the RX 7800 XT averages 11627. The nearest rivals confirm the NVIDIA card operates in a higher performance tier. Its closest rival, the NVIDIA Quadro GV100, scores 35520, only 0.2% off. The AMD card's closest rival, the NVIDIA GeForce GTX 1660, scores 11680, just 0.5% off. These figures show that the two cards exist in different performance classes despite the similar Passmark G3D scores.

The Verdict

The data indicates two GPUs optimized for different environments. The AMD Radeon RX 7800 XT is a desktop card with a 263 W TDP, dual-slot cooler, and dual 8-pin connectors. It delivers strong performance in traditional rasterization workloads, legacy DirectX paths, and Passmark's GPU compute test. Its 16 GB of GDDR6 memory on a 256-bit bus provides ample capacity for high-resolution textures. Its 37.32 TFLOPS of FP32 throughput is more than double the NVIDIA card's 17.04 TFLOPS, which explains its compute advantage in the Passmark test.

The NVIDIA GeForce RTX 5070 Ti Mobile is a laptop part with a 60 W TDP, no power connectors, and no dedicated slot. It achieves higher bandwidth (672.0 GB/s) through GDDR7 memory despite a narrower 192-bit bus. Its 184 tensor cores and 46 RT cores support AI and ray tracing workloads. Its Geekbench scores are dramatically higher, suggesting that the Blackwell architecture is far more efficient in compute-heavy synthetic benchmarks. The 80th percentile ranking versus the 51st percentile for AMD confirms that the NVIDIA part sits higher in the overall GPU distribution.

The choice depends on the use case. For legacy DirectX 9 and DirectX 11 titles, the RX 7800 XT is the stronger option. For DirectX 12, Geekbench OpenCL, and Geekbench Vulkan, the RTX 5070 Ti Mobile is clearly ahead. The Passmark G3D result is effectively a tie, meaning traditional gaming performance is comparable. The RX 7800 XT is a desktop part with a 263 W power draw, while the RTX 5070 Ti Mobile is a mobile part with 60 W. The NVIDIA card achieves comparable or better results in modern APIs while consuming far less power, but the AMD card retains advantages in specific compute and legacy workloads.
