AMD Radeon PRO W7900 vs NVIDIA RTX A3000 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a clear overall winner in the two benchmark tests shared between these GPUs. The AMD Radeon PRO W7900 wins both head-to-head comparisons, taking 2 wins out of 2 possible tests. The NVIDIA RTX A3000 Mobile does not win a single benchmark in this comparison.

In Geekbench OpenCL, the AMD Radeon PRO W7900 scores 84,379 points, while the NVIDIA RTX A3000 Mobile scores 79,091 points. This gives the AMD card a 6.7% advantage in this compute-oriented test. The margin is modest, suggesting that both cards are capable of handling OpenCL workloads, but the desktop-class AMD part maintains a clear edge.

The Geekbench Vulkan test tells a very different story. The AMD Radeon PRO W7900 scores 137,070 points, while the NVIDIA RTX A3000 Mobile scores 61,189 points. The delta here is a massive 124%, meaning the AMD card more than doubles the NVIDIA mobile GPU's Vulkan performance. This is the single largest gap between the two in any recorded metric. The Vulkan API, which is often used in gaming and real-time rendering, shows the AMD card operating in a different performance class entirely.

Looking at the average benchmark score across all recorded tests, the AMD Radeon PRO W7900 averages 110,725 points. The NVIDIA RTX A3000 Mobile averages 70,140 points. This represents a substantial overall performance gap of roughly 58% in favor of the AMD card. The percentile rankings reflect this gap: the AMD card sits in the 94th percentile of all GPUs in the database, while the NVIDIA card sits in the 91st percentile. Both are high-ranking parts, but the AMD card is closer to the top of the field.

Where Each One Wins

The AMD Radeon PRO W7900 wins in every benchmark category where both cards have recorded scores. In OpenCL, the 6.7% lead suggests that the AMD card is better suited for general-purpose GPU compute tasks, such as scientific simulations, data processing, and rendering workloads that rely on this API. The 124% lead in Vulkan is even more decisive, indicating that the AMD card is dramatically faster in real-time graphics and modern game engines that use Vulkan.

The NVIDIA RTX A3000 Mobile, despite losing both head-to-head tests, still has a respectable position in the database. Its nearest rival is the NVIDIA Quadro P6000, which scores 69,986 points, a delta of only 0.2%. The RTX A3000 Mobile also sits close to the AMD Radeon Pro WX 8200 (69,870 points, 0.4% delta) and the AMD Radeon RX 6600 LE (70,829 points, -1% delta). This suggests that the RTX A3000 Mobile is competitive with a specific tier of workstation and desktop GPUs, but it is not in the same league as the Radeon PRO W7900.

For the AMD Radeon PRO W7900, the nearest rivals include the NVIDIA RTX A5500 Mobile (113,944 points, -2.8% delta) and the NVIDIA Tesla V100 SXM2 16 GB (114,395 points, -3.2% delta). The AMD card is slightly ahead of these parts, and it is also ahead of the AMD Radeon Pro Vega II (109,617 points, 1% delta) and the AMD Radeon Pro W6600X (107,342 points, 3.2% delta). This places the W7900 in the upper tier of professional GPUs, just above several high-end competitors.

Architecture Differences

The two GPUs come from different manufacturers and use fundamentally different architectures. The AMD Radeon PRO W7900 is built on the Navi 31 chip using the RDNA 3.0 architecture, with the codename Plum Bonito. It belongs to the Radeon Pro Navi generation. The NVIDIA RTX A3000 Mobile uses the GA104 chip based on the Ampere architecture, belonging to the Ampere-MW generation.

The manufacturing process differs significantly. The AMD card uses a 5 nm process node from TSMC, while the NVIDIA card uses an 8 nm process node from Samsung. This process advantage is reflected in transistor density: the AMD chip packs 109.1 million transistors per square millimeter, while the NVIDIA chip has 44.4 million per square millimeter. The AMD chip contains 57,700 million transistors on a 529 mm² die, whereas the NVIDIA chip has 17,400 million transistors on a 392 mm² die.

Memory configurations are also very different. The AMD Radeon PRO W7900 has 48 GB of GDDR6 memory on a 384-bit bus, delivering 864.0 GB/s of bandwidth. The NVIDIA RTX A3000 Mobile has only 6 GB of GDDR6 memory on a 192-bit bus, with 264.0 GB/s of bandwidth. The AMD card offers 8 times the memory capacity and more than 3 times the bandwidth.

The compute resources show a similar disparity. The AMD card has 6,144 shading units, 384 texture mapping units, and 192 render output units. The NVIDIA card has 4,096 shading units, 128 TMUs, and 64 ROPs. The AMD card also has 96 ray tracing cores, while the NVIDIA card has 32. The NVIDIA card does have 128 tensor cores, a feature the AMD card does not list. Clock speeds differ as well: the AMD card has a base clock of 1760 MHz and a boost clock of 2495 MHz, while the NVIDIA card has a base clock of 600 MHz and a boost clock of 1230 MHz.

The resulting throughput numbers are far apart. The AMD card achieves 61.32 TFLOPS of FP32 performance and the same for FP16 (1:1 ratio). The NVIDIA card achieves 10.08 TFLOPS for both FP32 and FP16. Pixel rate is 479.0 GPixel/s for AMD versus 78.72 GPixel/s for NVIDIA. Texture rate is 958.1 GTexel/s versus 157.4 GTexel/s.

Power consumption reflects the desktop versus mobile design. The AMD card has a TDP of 295 W and requires 2x 8-pin power connectors, with a suggested PSU of 600 W. It is a triple-slot card measuring 280 mm in length, 110 mm in height, and 51 mm in width. The NVIDIA card has a TDP of 70 W and uses no external power connectors, as it is designed for portable devices where power delivery is dependent on the host system. The NVIDIA card has no listed dimensions or slot width.

Both cards support the same API levels: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD card has display outputs of 3x DisplayPort 2.1 and 1x mini-DisplayPort 2.1, while the NVIDIA card's display outputs are described as "Portable Device Dependent."

The Verdict

The data supports a straightforward conclusion. The AMD Radeon PRO W7900 is the superior performer in every recorded benchmark. It wins the OpenCL test by 6.7% and the Vulkan test by 124%. Its average benchmark score of 110,725 is roughly 58% higher than the NVIDIA RTX A3000 Mobile's average of 70,140. The AMD card also sits in a higher percentile (94th versus 91st) among all GPUs in the database.

Users who need maximum compute performance, especially in Vulkan-based workloads, should choose the AMD Radeon PRO W7900. The card's 48 GB memory capacity and 864.0 GB/s bandwidth make it suitable for large datasets and high-resolution rendering. The 61.32 TFLOPS FP32 performance places it well above the NVIDIA card's 10.08 TFLOPS.

The NVIDIA RTX A3000 Mobile is an end-of-life product, while the AMD card is still active in production. The NVIDIA card's predecessor is the Quadro Turing-M, and its successor is Ada-MW. The AMD card's predecessor is the Radeon Pro Vega. The AMD card was released on 2023-05-25, while the NVIDIA card was released on 2021-04-11.

For mobile workstations where power consumption is critical, the NVIDIA card's 70 W TDP and lack of external power connectors make it the only viable option in portable form factors. The AMD card's 295 W TDP and triple-slot design require a desktop workstation chassis. However, based purely on benchmark data, the AMD Radeon PRO W7900 is the clear winner for raw performance.
