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

Head-to-Head Benchmarks

The recorded data presents a stark split between the AMD Radeon RX 7800 XT and the NVIDIA GeForce RTX 5070 Mobile. Across nine head-to-head tests, the AMD card claims six wins, while the NVIDIA mobile part takes three. The margin of victory tells a more nuanced story than the raw win count.

The most dramatic result appears in Geekbench OpenCL. The RTX 5070 Mobile scores 122,238 against the RX 7800 XT's 18,290, a delta of -85% from the AMD card's perspective. That is an enormous gap, and it positions the NVIDIA part as the clear compute leader in this specific workload. The Geekbench Vulkan result follows a similar pattern: NVIDIA scores 116,960 versus 54,228 for AMD, a 53.6% deficit for the Radeon. These two tests alone suggest that NVIDIA's architecture holds a significant advantage in general-purpose and API-level compute tasks.

However, the PassMark suite flips the picture. In PassMark G3D, the RX 7800 XT scores 24,176 against 20,355 for the RTX 5070 Mobile, a lead of 18.8%. The AMD card also wins PassMark GPU Compute by a wide margin: 13,473 versus 8,279, a 62.7% advantage. The DirectX 9 test shows AMD ahead by 42.1%, scoring 304 versus 214, and DirectX 11 shows a 29.7% lead with 249 versus 192. PassMark G2D also favors AMD, 1,177 versus 896, a 31.4% edge.

The DirectX 12 test is a perfect tie at 93 each, with a delta of 0% and the win attributed to AMD by the database's tie-break convention. The DirectX 10 test is close, with NVIDIA ahead by just 6.2%, scoring 129 versus 121.

The average benchmark scores reflect these divergent strengths. The RTX 5070 Mobile averages 29,928 across its recorded benchmarks, while the RX 7800 XT averages 11,627. That average is heavily skewed by the massive Geekbench OpenCL score for NVIDIA. The percentile ranks also diverge: the RTX 5070 Mobile sits at the 75th percentile among all GPUs, while the RX 7800 XT sits at the 51st percentile. The nearest rivals listed in the database reinforce this positioning. The RTX 5070 Mobile's closest competitor is the RTX 3070 Ti, with a delta of -0.1%, followed by the RTX 2080 Ti at 0.5%, the RX 6800 at -0.6%, and the RX 6700 at -1.7%. The RX 7800 XT's nearest rivals are far lower in the hierarchy: the GTX 1660 at -0.5%, the Radeon Pro 5500M at 0.9%, the Tesla K20c at 1.3%, and the RX 6500 XT at -1.8%.

The Verdict

The data indicates two very different products with two very different intended roles. The RTX 5070 Mobile is a laptop GPU with a 50 W TDP, and its benchmark profile favors compute-heavy APIs. The RX 7800 XT is a desktop card with a 263 W TDP, and it dominates the rasterization-focused PassMark tests. The verdict from the numbers is straightforward: the RX 7800 XT is the stronger traditional graphics card, while the RTX 5070 Mobile excels in compute-oriented benchmarks.

For users prioritizing DirectX 11, DirectX 9, G2D, G3D, and GPU compute in PassMark, the RX 7800 XT is the clear choice. Its leads range from 18.8% in G3D to 62.7% in GPU compute. For those prioritizing OpenCL or Vulkan performance, the RTX 5070 Mobile delivers results that the AMD card cannot approach, with an 85% gap in OpenCL and a 53.6% gap in Vulkan.

The tie in DirectX 12 and the near-tie in DirectX 10 (NVIDIA ahead by 6.2%) suggest that modern API performance is closer than the older DirectX tests imply. The RTX 5070 Mobile's 75th percentile rank against all GPUs, compared to the RX 7800 XT's 51st percentile, indicates that the database's broader ranking favors the NVIDIA part, largely due to its compute scores. The RX 7800 XT's nearest rivals are older or lower-tier cards, which reflects its lower average benchmark score but does not capture its strength in specific rasterization workloads.

Architecture Differences

The two GPUs come from different architectural generations and design philosophies. The RX 7800 XT uses the Navi 32 chip with RDNA 3.0 architecture, part of the Navi III (RX 7000) generation. The RTX 5070 Mobile uses the GB206 chip with Blackwell 2.0 architecture, part of the GeForce 50 Mobile generation. Both are built on a 5 nm process at TSMC, but the similarities end there.

The RX 7800 XT packs 28,100 million transistors on a 346 mm² die, giving a transistor density of 81.2M per mm². The RTX 5070 Mobile has 21,900 million transistors on a much smaller 181 mm² die, achieving a higher density of 121.0M per mm². The smaller die and higher density reflect the mobile part's more constrained power envelope.

Clock speeds differ substantially. The RX 7800 XT runs at a base of 1295 MHz, a boost of 2430 MHz, and a game clock of 2124 MHz. The RTX 5070 Mobile runs at a base of 907 MHz and a boost of 1425 MHz, with no game clock listed. The AMD card's higher clocks contribute to its strong rasterization performance, while the NVIDIA part's lower clocks align with its 50 W TDP.

Memory configurations also diverge. The RX 7800 XT has 16 GB of GDDR6 on a 256-bit bus, delivering 624.1 GB/s of bandwidth. The RTX 5070 Mobile has 8 GB of GDDR7 on a 128-bit bus, delivering 384.0 GB/s. The AMD card has double the memory capacity and significantly more bandwidth, which helps explain its G3D and GPU compute wins. The RTX 5070 Mobile uses faster GDDR7 memory, but the narrower bus limits total bandwidth.

Shader and fixed-function hardware differ as well. The RX 7800 XT has 3,840 shading units, 240 texture mapping units, and 96 ROPs. The RTX 5070 Mobile has 4,608 shading units, 144 TMUs, and 48 ROPs. The NVIDIA part has more shading units but far fewer TMUs and ROPs, which likely contributes to its weaker PassMark rasterization results. Ray tracing cores also differ: 60 for AMD versus 36 for NVIDIA. The RTX 5070 Mobile includes 144 tensor cores, while the RX 7800 XT has none listed.

Pixel and texture rates reflect these differences. The RX 7800 XT achieves 233.3 GPixel/s and 583.2 GTexel/s, while the RTX 5070 Mobile achieves 68.40 GPixel/s and 205.2 GTexel/s. FP32 compute is also higher on the AMD card: 37.32 TFLOPS versus 13.13 TFLOPS, with both offering 1:1 FP16 ratios. The power draw tells a clear story: 263 W for AMD versus 50 W for NVIDIA. The RX 7800 XT requires a dual-slot design with two 8-pin connectors and a 600 W suggested PSU, while the RTX 5070 Mobile is an IGP with no power connectors.

Where Each One Wins

The RX 7800 XT wins in PassMark G3D, the most direct rasterization-oriented test, with a score of 24,176 versus 20,355. It also wins PassMark GPU Compute by a large margin, 13,473 versus 8,279, which suggests stronger general compute throughput in that specific benchmark framework. The DirectX 9 and DirectX 11 tests both favor AMD, with leads of 42.1% and 29.7% respectively. The G2D test also goes to AMD, 1,177 versus 896, indicating better 2D performance. The DirectX 12 test is tied at 93, with the database assigning the win to AMD.

The RTX 5070 Mobile wins the two Geekbench tests decisively. The OpenCL score of 122,238 dwarfs the AMD card's 18,290, and the Vulkan score of 116,960 versus 54,228 is also a commanding lead. The DirectX 10 test goes to NVIDIA, but by a narrow 6.2% margin, 129 versus 121.

The use-case split is clear. The RX 7800 XT is the choice for older DirectX workloads and PassMark's rasterization and compute tests. The RTX 5070 Mobile is the choice for OpenCL and Vulkan workloads, where its scores indicate a fundamentally different compute architecture. The tie in DirectX 12 means modern API users may not see a decisive winner in that specific test.
