AMD Radeon PRO W7800 vs NVIDIA RTX A3000 Mobile Comparison

Head-to-Head Benchmarks

The benchmark results are decisive in favor of the AMD Radeon PRO W7800. In Geekbench OpenCL, the AMD card scores 154366, while the NVIDIA RTX A3000 Mobile scores 79091, giving the AMD part a 95.2% advantage. In Geekbench Vulkan, the gap widens further: the AMD card reaches 175422, whereas the NVIDIA mobile GPU manages 61189, a delta of 186.7%. Both head-to-head tests are won by the AMD Radeon PRO W7800, with two wins and zero losses.

The average benchmark score tells the same story. The AMD Radeon PRO W7800 posts an average score of 164894, placing it in the 97th percentile among all GPUs in the database. The NVIDIA RTX A3000 Mobile averages 70140, which sits in the 91st percentile. That percentile gap, six points, understates the raw performance difference because the mobile part is competing against a lower baseline of notebook-class GPUs, while the desktop workstation card is measured against all GPUs regardless of form factor.

Looking at the nearest rival lists reinforces the interpretation. The AMD Radeon PRO W7800 sits within 0.2% of the NVIDIA RTX A5500, which averages 165217, and within 0.7% of the NVIDIA RTX 4500 Ada Generation, which averages 166094. It is 1.5% ahead of the NVIDIA A100 PCIe 40 GB at 162504 and 2.2% behind the AMD Radeon Pro W6900X at 168574. The NVIDIA RTX A3000 Mobile, by contrast, is only 0.2% ahead of the NVIDIA Quadro P6000 at 69986, 0.4% ahead of the AMD Radeon Pro WX 8200 at 69870, 1% behind the AMD Radeon RX 6600 LE at 70829, and 1.7% ahead of the NVIDIA CMP 90HX at 69000. The competitive positioning confirms that the AMD card belongs to a much higher performance tier.

The Vulkan result deserves particular attention. A 186.7% lead in that API test indicates that the AMD Radeon PRO W7800 scales especially well in the lower-level graphics workload. The OpenCL result, while still a clear win at 95.2%, shows a smaller relative margin, suggesting that the compute-oriented workload narrows the gap somewhat, though the AMD card still doubles the NVIDIA mobile part's score.

The Verdict

The data indicates that the AMD Radeon PRO W7800 is the superior performer in every recorded benchmark. Any user choosing between these two based on the database measurements should select the AMD part if raw compute and graphics throughput are the primary criteria. The AMD card wins both head-to-head tests, holds a higher average benchmark score, and occupies a higher percentile rank.

The NVIDIA RTX A3000 Mobile is a laptop component with a 70 W TDP, no power connectors, and end-of-life production status. It is not competitive with the desktop workstation card on any recorded metric. There is no benchmark category in which the NVIDIA part leads. The verdict from the data is unambiguous: the AMD Radeon PRO W7800 is the stronger GPU across all tested workloads.

Architecture Differences

The AMD Radeon PRO W7800 uses the Navi 31 chip built on TSMC's 5 nm process, with the RDNA 3.0 architecture and the Plum Bonito codename. It belongs to the Radeon Pro Navi (Navi III Series) generation. The NVIDIA RTX A3000 Mobile uses the GA104 chip built on Samsung's 8 nm process, with the Ampere architecture and the Ampere-MW (Ax000) generation. The process node difference, 5 nm versus 8 nm, is a significant architectural differentiator, as is the foundry: TSMC for AMD, Samsung for NVIDIA.

Transistor counts differ enormously. The AMD chip packs 57,700 million transistors on a 529 mm² die, yielding a transistor density of 109.1 million per mm². The NVIDIA chip contains 17,400 million transistors on a 392 mm² die, with a density of 44.4 million per mm². The AMD die is larger in absolute terms and more than twice as dense.

Ray tracing hardware also differs. The AMD card carries 70 ray tracing cores, while the NVIDIA mobile part has 32. The NVIDIA card does include 128 tensor cores, a feature the AMD card does not list. Shading units are close: 4480 for the AMD card versus 4096 for the NVIDIA card. Texture mapping units favor AMD at 280 versus 128, and raster output units favor AMD at 128 versus 64.

The AMD card supports DisplayPort 2.1 outputs, with three full-size DisplayPort 2.1 ports and one mini-DisplayPort 2.1. The NVIDIA card's display outputs are listed as portable device dependent, reflecting its mobile nature. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature levels match.

Specification Differences

Memory capacity differs sharply. The AMD Radeon PRO W7800 has 32 GB of GDDR6 memory on a 256-bit bus, with memory clocked at 2250 MHz (18 Gbps effective) and bandwidth of 576.0 GB/s. The NVIDIA RTX A3000 Mobile has 6 GB of GDDR6 memory on a 192-bit bus, with memory clocked at 1375 MHz (11 Gbps effective) and bandwidth of 264.0 GB/s. The AMD card offers more than five times the memory capacity and more than double the bandwidth.

Clock speeds also diverge. The AMD card runs at a base clock of 1895 MHz and boosts to 2525 MHz. The NVIDIA card runs at a base clock of 600 MHz and boosts to 1230 MHz. The boost clock difference alone, 2525 MHz versus 1230 MHz, explains much of the performance gap.

Compute throughput figures reflect the clock and core differences. The AMD card delivers 45.25 TFLOPS of FP32 performance and 90.50 TFLOPS of FP16 (2:1). The NVIDIA card delivers 10.08 TFLOPS of FP32 and 10.08 TFLOPS of FP16 (1:1). The AMD card is roughly 4.5 times faster in FP32 and 9 times faster in FP16. Pixel rate is 323.2 GPixel/s for the AMD card versus 78.72 GPixel/s for the NVIDIA card. Texture rate is 707.0 GTexel/s versus 157.4 GTexel/s.

Power and physical specifications differ as expected for a desktop versus mobile part. The AMD card has a 260 W TDP, is dual-slot, requires two 8-pin power connectors, and lists a 600 W suggested PSU. The NVIDIA card has a 70 W TDP, lists no power connectors, and no suggested PSU. The AMD card measures 280 mm (11 inches) in length, 110 mm (4.3 inches) in height, and 40 mm (1.6 inches) in width. The NVIDIA card has no recorded dimensions.

Bus interface is identical: PCIe 4.0 x16 for both. Production status differs, with the AMD card active and the NVIDIA card end-of-life. Release dates are roughly two years apart, with the AMD card released on April 12, 2023, and the NVIDIA card on April 11, 2021. The AMD card's launch MSRP is 2,499 USD, while the NVIDIA card has no recorded launch MSRP. The AMD card's predecessor is the Radeon Pro Vega, and the NVIDIA card's predecessor is the Quadro Turing-M, with the NVIDIA card's successor listed as Ada-MW.

Where Each One Wins

The AMD Radeon PRO W7800 wins every recorded benchmark category. In Geekbench OpenCL, it delivers a 95.2% advantage, establishing it as the stronger choice for OpenCL compute workloads. In Geekbench Vulkan, the 186.7% lead makes it the clear winner for Vulkan-based rendering and graphics tasks. The AMD card also holds the advantage in memory capacity, bandwidth, clock speeds, FP32 throughput, FP16 throughput, pixel rate, and texture rate.

The NVIDIA RTX A3000 Mobile has no benchmark wins in the recorded data. Its only listed advantages are architectural: it includes 128 tensor cores, which the AMD card does not list, and it has a far lower TDP of 70 W, making it appropriate for portable workstations where power draw and thermal output are constrained. Its smaller physical footprint, with no recorded dimensions and no power connectors, reflects its mobile design intent.

For desktop workstation workloads where performance is the priority, the AMD Radeon PRO W7800 is the data-backed choice. For mobile workstation scenarios requiring low power consumption and integrated laptop operation, the NVIDIA RTX A3000 Mobile exists as the only portable option in this comparison, but the benchmark record shows no performance category where it surpasses the AMD card.
