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

Head-to-Head Benchmarks

The benchmark database records a decisive sweep in the head-to-head comparison between the AMD Radeon RX 7800M and the NVIDIA GeForce RTX 5070 Ti Mobile. Across all nine shared tests, the NVIDIA part posts the higher score. The most lopsided margin appears in the PassMark DirectX 10 test, where the RTX 5070 Ti Mobile scores 151 against the RX 7800M's 99, a 34.4% advantage. DirectX 9 shows a similar gap: 259 versus 174, a 32.8% lead for the NVIDIA GPU. These legacy API results indicate that the GeForce architecture retains substantial performance headroom in older rendering paths.

The 3D gaming-oriented PassMark G3D test also favors the RTX 5070 Ti Mobile heavily. NVIDIA scores 24004 while AMD manages 17613, a 26.6% deficit. This is the single most relevant indicator for general gaming performance in the recorded data, and it places the GeForce part firmly ahead. DirectX 11 results follow the same pattern: 237 versus 176, a 25.7% gap. DirectX 12 narrows the margin somewhat, with NVIDIA at 102 and AMD at 89, a 12.7% difference. That closer result suggests the RDNA 3.0 architecture closes some of the gap in modern low-level APIs, but it does not overcome the overall performance deficit.

Compute workloads tell a more nuanced story. In Geekbench OpenCL, the RTX 5070 Ti Mobile scores 143870 against 120778 for the RX 7800M, a 16.1% advantage. The Vulkan result is tighter: 139213 versus 126668, a 9% lead for NVIDIA. PassMark GPU Compute shows the smallest gap of any test, with NVIDIA at 10101 and AMD at 9342, a 7.5% difference. The 2D performance test, PassMark G2D, also goes to NVIDIA: 981 versus 892, a 9.1% margin. Across the full suite, the RTX 5070 Ti Mobile wins every single head-to-head test, recording 9 wins and 0 losses. The average benchmark score reinforces this: NVIDIA averages 35435, AMD averages 27883, a difference of roughly 7552 points.

The Verdict

The recorded data points to a clear hierarchy. The NVIDIA GeForce RTX 5070 Ti Mobile sits at the 80th percentile among all GPUs in the database, while the AMD Radeon RX 7800M sits at the 73rd percentile. The average score gap is substantial: 35435 versus 27883. The NVIDIA part leads in every measured category, from legacy DirectX 9 to modern DirectX 12, from OpenCL compute to Vulkan rendering. The smallest margins appear in compute-oriented tests, where the AMD GPU comes within 7.5% in PassMark GPU Compute and 9% in Vulkan, but even there it does not take a single win.

The RTX 5070 Ti Mobile's nearest rivals in the database include the NVIDIA Quadro GV100 at 35520 (0.2% higher), the AMD Radeon Pro Duo at 35860 (1.2% higher), and the NVIDIA T1000 at 36289 (2.4% higher). The RX 7800M, by contrast, sits near the AMD Radeon Pro Vega 20 at 27839 (0.2% lower), the AMD Radeon Pro W5500X at 27973 (0.3% higher), and the NVIDIA GeForce GTX 980 Ti at 28020 (0.5% higher). The performance class separation is evident: the RTX 5070 Ti Mobile competes at a tier roughly 25% higher in average score than the RX 7800M.

For any workload represented in the database, the RTX 5070 Ti Mobile is the stronger choice. The RX 7800M does not win a single benchmark, so the verdict from the data is unambiguous. The only consideration that favors AMD on paper is the architecture's different feature set and transistor layout, but in measured performance, NVIDIA holds the advantage across the board.

Architecture Differences

The two GPUs come from different architectural generations and design philosophies. The AMD Radeon RX 7800M uses the Navi 32 chip built on RDNA 3.0 architecture, codenamed Wheat Nas, part of the Navi Mobile (RX 7000M) generation. The NVIDIA GeForce RTX 5070 Ti Mobile uses the GB205 chip on Blackwell 2.0 architecture, part of the GeForce 50 Mobile generation. Both are fabricated by TSMC on a 5 nm process, but the transistor counts differ: AMD packs 28,100 million transistors on a 346 mm² die, while NVIDIA fits 31,100 million transistors on a smaller 263 mm² die. This yields a significantly higher transistor density for NVIDIA at 118.3M per mm² versus 81.2M per mm² for AMD.

The compute unit configurations diverge sharply. The RX 7800M carries 3840 shading units, 240 texture mapping units, and 96 raster operation pipelines. The RTX 5070 Ti Mobile has 5888 shading units but fewer TMUs at 184 and fewer ROPs at 80. The AMD part also has 60 ray tracing cores, while NVIDIA has 46 RT cores but adds 184 tensor cores, a feature the AMD GPU lacks entirely. The clock speeds reflect different operating strategies: AMD runs a base clock of 1295 MHz and a boost clock of 2335 MHz, with a game clock of 2145 MHz. NVIDIA runs lower clocks at 847 MHz base and 1447 MHz boost, yet still achieves higher benchmark scores, indicating the architectural efficiency of Blackwell 2.0 compensates for the clock deficit.

Memory configurations share the same capacity and bus width: both have 12 GB and a 192 bit interface. The memory type differs, with AMD using GDDR6 and NVIDIA using GDDR7. The effective memory speed for NVIDIA is 28 Gbps, producing 672.0 GB/s of bandwidth, while AMD runs at 18 Gbps effective, yielding 432.0 GB/s. This 240 GB/s bandwidth advantage for NVIDIA likely contributes to its performance lead in memory-intensive workloads. The power profiles differ just as dramatically: AMD is rated at 180 W TDP, while NVIDIA is rated at 60 W TDP. Both are integrated GPUs with no dedicated power connectors and portable-device-dependent display outputs. The bus interface also differs: AMD uses PCIe 4.0 x16, NVIDIA uses PCIe 5.0 x16.

The theoretical throughput numbers are inverted relative to the benchmark results. AMD reports 35.87 TFLOPS FP32 and matching FP16 performance, with a pixel rate of 224.2 GPixel/s and a texture rate of 560.4 GTexel/s. NVIDIA reports only 17.04 TFLOPS FP32 and FP16, with a pixel rate of 115.8 GPixel/s and a texture rate of 266.2 GTexel/s. Despite AMD's roughly 2x advantage in raw FLOPs and fill rates, the RTX 5070 Ti Mobile wins all benchmarks. This indicates that the Blackwell architecture extracts more usable performance per FLOP, or that the benchmark workloads favor NVIDIA's scheduling and memory subsystem. The API support is identical: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Where Each One Wins

The RTX 5070 Ti Mobile wins every benchmark in the database, so the use-case split is defined by the size of its advantage rather than any AMD victories. The largest leads for NVIDIA appear in legacy DirectX workloads: 34.4% in DirectX 10 and 32.8% in DirectX 9. These tests reflect older game engines and compatibility layers, where the NVIDIA architecture shows the strongest relative performance. The DirectX 11 gap of 25.7% and the G3D gap of 26.6% indicate that mainstream gaming workloads also strongly favor the GeForce part. For users running a typical mix of DX11-era and current games, the RTX 5070 Ti Mobile delivers a substantially higher frame rate.

The RX 7800M comes closest in compute-oriented tests. The PassMark GPU Compute margin is only 7.5%, the Vulkan margin is 9%, and the G2D margin is 9.1%. These smaller gaps suggest that in raw compute throughput, the AMD GPU's higher FP32 figure of 35.87 TFLOPS partially offsets the NVIDIA architecture's efficiency. The DirectX 12 test also shows a relatively narrow 12.7% gap, hinting that modern low-level APIs reduce the NVIDIA lead. For users running Vulkan-based titles or OpenCL compute workloads, the RX 7800M remains competitive even though it does not take the win.

The RTX 5070 Ti Mobile's bandwidth advantage (672.0 GB/s versus 432.0 GB/s) and its 184 tensor cores give it a structural edge in workloads that leverage those features. The 80th percentile ranking versus 73rd percentile places it in a higher overall performance class. The RX 7800M's higher pixel rate (224.2 GPixel/s versus 115.8 GPixel/s) and texture rate (560.4 GTexel/s versus 266.2 GTexel/s) do not translate into benchmark wins, which suggests the measured workloads are not fill-rate limited. The data records no scenario where the AMD GPU finishes ahead, so the practical conclusion is that the RTX 5070 Ti Mobile is the stronger choice for every test in the database, with the RX 7800M best suited to compute-heavy applications where the performance gap narrows to single digits.
