AMD Radeon PRO W7900 vs NVIDIA GeForce RTX 5070 Mobile Comparison

The Verdict

The recorded benchmark data presents a split decision between these two GPUs, with each winning one of the two shared tests. The AMD Radeon PRO W7900 takes the Geekbench Vulkan test with a score of 137070 against the NVIDIA GeForce RTX 5070 Mobile's 116960, a 17.2% advantage. The NVIDIA part wins the Geekbench OpenCL test decisively, scoring 122238 against the AMD card's 84379, a 31% margin in NVIDIA's favor.

The overall database percentile rankings place these parts in different tiers. The AMD Radeon PRO W7900 sits at the 94th percentile of all GPUs, with an average benchmark score of 110725. The NVIDIA GeForce RTX 5070 Mobile ranks at the 75th percentile, with an average score of 29928. That large gap in average scores stems from the fact that the AMD card has only two recorded benchmark entries, both from Geekbench, while the NVIDIA mobile part has nine entries across Passmark and Geekbench suites, and several of those Passmark scores are quite low.

For professionals running Vulkan workloads, the data clearly favors the AMD Radeon PRO W7900. Its 96 ray accelerators, 6144 shading units, and 48 GB of GDDR6 memory on a 384-bit bus with 864.0 GB/s of bandwidth position it as a workstation part with substantial compute resources. The NVIDIA GeForce RTX 5070 Mobile, with 4608 shading units, 36 RT cores, 144 tensor cores, and 8 GB of GDDR7 on a 128-bit bus delivering 384.0 GB/s, is a mobile part designed for a different power envelope.

The OpenCL result is interesting because it contradicts the raw specifications. Despite having fewer shading units, lower clock speeds, and less memory bandwidth, the RTX 5070 Mobile posts a 31% higher OpenCL score. This likely reflects driver optimization, architecture efficiency, or differences in how each part handles the OpenCL workload. The data does not explain the cause; it only records the outcome.

Architecture Differences

The AMD Radeon PRO W7900 uses the Navi 31 chip based on RDNA 3.0 architecture, with the codename Plum Bonito, and belongs to the Radeon Pro Navi (Navi III Series) generation. The NVIDIA GeForce RTX 5070 Mobile uses the GB206 chip based on Blackwell 2.0 architecture and belongs to the GeForce 50 Mobile generation. Both are fabricated on a 5 nm process at TSMC, but the AMD chip is substantially larger at 529 mm² compared to the NVIDIA chip's 181 mm².

The transistor counts reflect this size difference. The AMD chip packs 57,700 million transistors, while the NVIDIA chip contains 21,900 million. Interestingly, the NVIDIA chip achieves a higher transistor density of 121.0M per mm² versus the AMD chip's 109.1M per mm², indicating a denser packing of logic.

Compute resources differ significantly. The AMD Radeon PRO W7900 has 6144 shading units, 384 texture mapping units, and 192 raster output pipelines. It also includes 96 ray accelerators but has no tensor cores. The NVIDIA GeForce RTX 5070 Mobile has 4608 shading units, 144 TMUs, and 48 ROPs, along with 36 RT cores and 144 tensor cores. The presence of 144 tensor cores on the NVIDIA part indicates AI acceleration hardware that the AMD part lacks entirely.

Clock speeds show a stark contrast. The AMD card runs at a base clock of 1760 MHz and boosts to 2495 MHz. The NVIDIA mobile part runs at a much lower 907 MHz base and 1425 MHz boost. Despite the lower clocks, the NVIDIA part achieves competitive or better scores in some tests, suggesting architectural efficiency differences rather than raw clock speed advantages.

The memory architectures are fundamentally different. AMD uses 48 GB of GDDR6 with a 384-bit bus and memory clock of 2250 MHz (18 Gbps effective), delivering 864.0 GB/s bandwidth. NVIDIA uses 8 GB of GDDR7 with a 128-bit bus and memory clock of 1500 MHz (24 Gbps effective), delivering 384.0 GB/s. The AMD card has over twice the bandwidth, but the NVIDIA part uses newer GDDR7 technology.

Specification Differences

The recorded specifications show a workstation desktop card versus a mobile integrated part. The AMD Radeon PRO W7900 is a triple-slot card measuring 280 mm in length, 110 mm in height, and 51 mm in width. It uses PCIe 4.0 x16 and has display outputs of 3x DisplayPort 2.1 and 1x mini-DisplayPort 2.1. The NVIDIA GeForce RTX 5070 Mobile is an IGP with no physical dimensions recorded, uses PCIe 5.0 x16, and its display outputs are listed as portable device dependent.

Power requirements differ by an order of magnitude. The AMD card has a 295 W TDP, requires a 600 W suggested power supply, and uses two 8-pin power connectors. The NVIDIA mobile part has a 50 W TDP and no power connectors, as it draws power through the portable device's motherboard.

Pixel and texture rates reflect the massive compute difference. The AMD card achieves 479.0 GPixel/s and 958.1 GTexel/s. The NVIDIA part achieves 68.40 GPixel/s and 205.2 GTexel/s. FP32 performance is 61.32 TFLOPS for AMD versus 13.13 TFLOPS for NVIDIA, and both have 1:1 FP16 to FP32 ratios.

The AMD card has a launch MSRP of 3,999 USD. The NVIDIA mobile part has no recorded launch MSRP. The AMD card's predecessor is the Radeon Pro Vega, while the NVIDIA part's predecessor is the GeForce 40 Mobile. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Head-to-Head Benchmarks

The shared benchmark suite contains only two tests, and each GPU wins one. The Geekbench Vulkan test shows the AMD Radeon PRO W7900 scoring 137070 against the NVIDIA GeForce RTX 5070 Mobile's 116960, a 17.2% margin. In Geekbench OpenCL, the NVIDIA part scores 122238 against the AMD card's 84379, a 31% margin.

The OpenCL result is particularly striking given the specification sheet. The AMD card has 33% more shading units (6144 versus 4608), 75% more TMUs (384 versus 144), 4x the ROPs (192 versus 48), and more than double the memory bandwidth (864.0 GB/s versus 384.0 GB/s). Its FP32 throughput of 61.32 TFLOPS is more than 4.5x the NVIDIA part's 13.13 TFLOPS. Yet the OpenCL score favors NVIDIA by 31%. This suggests that raw compute resources do not directly translate to OpenCL performance in this comparison.

The Vulkan result aligns more closely with the hardware specifications. The AMD card's 17.2% lead in Vulkan is smaller than its raw compute advantage would suggest, but it does win. This indicates that Vulkan workloads better utilize the AMD architecture's resources, possibly leveraging its larger memory pool or wider memory bus.

Looking at the broader benchmark database, the AMD Radeon PRO W7900's nearest rivals include the NVIDIA RTX A5500 Mobile with an average score of 113944 and a delta of -2.8%, and the NVIDIA Tesla V100 SXM2 16 GB with an average score of 114395 and a delta of -3.2%. The AMD part sits 1% above its predecessor, the AMD Radeon Pro Vega II (109617), and 3.2% above the AMD Radeon Pro W6600X (107342).

The NVIDIA GeForce RTX 5070 Mobile's nearest rivals are all desktop parts from previous generations. It sits 0.1% below the NVIDIA GeForce RTX 3070 Ti (29945), 0.5% above the NVIDIA GeForce RTX 2080 Ti (29783), 0.6% below the AMD Radeon RX 6800 (30095), and 1.7% below the AMD Radeon RX 6700 (30433). This places the mobile part's average performance in the same range as those desktop GPUs, despite its 50 W power envelope.

The Passmark scores for the NVIDIA part show a wide spread. Passmark G3D scores 20355, while Passmark GPU Compute scores 8279. DirectX 9 scores 214, DirectX 11 scores 192, DirectX 10 scores 129, and DirectX 12 scores 93. Passmark G2D scores 896. These results show the mobile part performs best in G3D and compute workloads, while older DirectX tests show lower numbers.

The win count in the head-to-head is exactly one each, making this a balanced matchup. The choice between these two parts depends entirely on the workload and the physical constraints of the system. A desktop workstation requiring Vulkan performance and massive memory capacity would favor the AMD card. A portable device needing OpenCL performance within a 50 W envelope would favor the NVIDIA part. The data does not declare an overall winner; it presents two different performance profiles for two different use cases.
