AMD Radeon PRO W7900 vs NVIDIA GeForce RTX 5080 SUPER Comparison

The Verdict

The AMD Radeon PRO W7900 and NVIDIA GeForce RTX 5080 SUPER occupy entirely different positions in the database. The AMD card holds a 94th percentile rank against all GPUs, with an average benchmark score of 110,725 across two recorded tests. The NVIDIA card sits at the 19th percentile, with an average benchmark score of 3,075 from a single recorded test. These percentile positions indicate that the Radeon PRO W7900 competes among the highest-performing cards in the database, while the RTX 5080 SUPER's recorded data places it near lower-tier entries, though that result comes from only one workload. The AMD card's nearest rivals, such as the NVIDIA Tesla V100 SXM2 16 GB at a 3.2% higher average score and the NVIDIA RTX A5500 Mobile at 2.8% higher, confirm its placement in the upper echelon. The RTX 5080 SUPER's nearest rivals include the Intel Arc Pro B60 at 3.4% higher and the NVIDIA Quadro P1000 at 2.8% higher, which positions its single recorded score in a much lower performance bracket. Users requiring massive memory capacity and professional workstation compute should select the Radeon PRO W7900. Users targeting the RTX 5080 SUPER would rely on its newer interface and higher clock rates, but the recorded benchmark data does not support a performance advantage over the AMD card.

Architecture Differences

The two cards use different silicon from different architectural families. AMD's Radeon PRO W7900 uses the Navi 31 chip built on RDNA 3.0 architecture, with the codename Plum Bonito. NVIDIA's RTX 5080 SUPER uses the GB203 chip built on Blackwell 2.0 architecture and belongs to the GeForce 50-series generation. Both chips are manufactured on a 5 nm process at TSMC, but the transistor counts differ substantially. The AMD chip contains 57,700 million transistors on a 529 mm² die, producing a transistor density of 109.1M per mm². The NVIDIA chip contains 45,600 million transistors on a 378 mm² die, yielding a higher transistor density of 120.6M per mm². The AMD die is 151 mm² larger and holds 12,100 million more transistors.

Clock behavior also separates the two. The Radeon PRO W7900 has a base clock of 1760 MHz and a boost clock of 2495 MHz. The RTX 5080 SUPER has a base clock of 2295 MHz and a boost clock of 2617 MHz, which is 535 MHz higher at base and 122 MHz higher at boost. Memory technology differs completely. AMD uses 48 GB of GDDR6 on a 384-bit bus with a memory clock of 2250 MHz (18 Gbps effective), producing 864.0 GB/s of bandwidth. NVIDIA uses 24 GB of GDDR7 on a 256-bit bus with a memory clock of 2000 MHz (32 Gbps effective), producing 1.02 TB/s of bandwidth. The NVIDIA card delivers 18.1% more bandwidth despite having half the capacity and a narrower bus, because GDDR7 operates at a higher effective data rate.

Compute unit organization differs as well. The AMD card has 6,144 shading units, 384 texture mapping units, 192 render output units, and 96 ray tracing cores. The NVIDIA card has 10,752 shading units, 336 TMUs, 112 ROPs, 84 ray tracing cores, and 336 tensor cores. The AMD card has no tensor core field recorded, while the NVIDIA card includes dedicated tensor cores. The interface generation differs: AMD uses PCIe 4.0 x16, while NVIDIA uses PCIe 5.0 x16. Physical dimensions diverge, with the AMD card measuring 280 mm in length, 110 mm in height, and 51 mm in width, while the NVIDIA card measures 304 mm in length, 137 mm in height, and 40 mm in width. The AMD card is shorter and narrower but thicker, occupying a triple-slot design with two 8-pin power connectors and a 600 W suggested PSU. The NVIDIA card uses a dual-slot design with a single 16-pin connector and no recorded suggested PSU. Power draw differs, with the AMD card rated at 295 W and the NVIDIA card at 415 W, a 120 W gap. Display outputs also differ, with AMD offering three DisplayPort 2.1 and one mini-DisplayPort 2.1, while NVIDIA offers one HDMI 2.1b and three DisplayPort 2.1b. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Where Each One Wins

The AMD Radeon PRO W7900 wins decisively in the recorded benchmark data. In the Geekbench OpenCL test, it scores 84,379. In the Geekbench Vulkan test, it scores 137,070. These two results produce an average benchmark score of 110,725. The NVIDIA RTX 5080 SUPER has only one recorded benchmark, the 3DMark Steel Nomad DX12 test, where it scores 3,075. That single score serves as its average. Because the head-to-head benchmark list is empty, direct comparisons across identical workloads are not available. The database shows the AMD card winning zero head-to-head matchups and the NVIDIA card winning zero as well, reflecting the absence of shared test data rather than a competitive tie.

The AMD card's strength lies in memory capacity and workstation-oriented specifications. Its 48 GB of GDDR6 memory is double the 24 GB on the NVIDIA card. Its 864.0 GB/s bandwidth is lower than the NVIDIA card's 1.02 TB/s, but the capacity advantage matters for large datasets. The AMD card also has a higher pixel rate at 479.0 GPixel/s versus 293.1 GPixel/s, a 63.4% advantage. Its texture rate of 958.1 GTexel/s exceeds the NVIDIA card's 879.3 GTexel/s by 9.0%. Its FP32 compute of 61.32 TFLOPS exceeds the NVIDIA card's 56.28 TFLOPS by 9.0%. Its FP16 compute also sits at 61.32 TFLOPS versus 56.28 TFLOPS, again a 9.0% advantage.

The NVIDIA card wins on several specification-level metrics. Its boost clock of 2617 MHz is 122 MHz higher than the AMD card's 2495 MHz. Its base clock of 2295 MHz is 535 MHz higher. Its memory bandwidth of 1.02 TB/s exceeds the AMD card's 864.0 GB/s by 18.1%. Its transistor density of 120.6M per mm² exceeds the AMD card's 109.1M per mm² by 10.5%. Its shading unit count of 10,752 is 75.0% higher than the AMD card's 6,144. Its 336 tensor cores provide AI acceleration capabilities that the AMD card does not record. Its PCIe 5.0 x16 interface is one generation newer than the AMD card's PCIe 4.0 x16. Its dual-slot form factor is thinner than the AMD card's triple-slot design, and its 304 mm length and 137 mm height make it a larger board overall, though only 40 mm thick.

Head-to-Head Benchmarks

The head-to-head benchmark list is empty, so no directly comparable test scores exist between the two cards. The database records the AMD card's performance in Geekbench OpenCL and Geekbench Vulkan, while the NVIDIA card's only recorded result comes from 3DMark Steel Nomad DX12. These tests measure different workloads and cannot be directly compared. However, the overall percentile positions tell a clear story. The AMD card sits at the 94th percentile against all GPUs, meaning 94% of recorded GPUs score lower. The NVIDIA card sits at the 19th percentile, meaning 81% of recorded GPUs score higher. That gap of 75 percentile points is substantial.

The AMD card's nearest rivals in the database are the NVIDIA Tesla V100 SXM2 16 GB at 114,395 average score (3.2% higher than the AMD card), the NVIDIA RTX A5500 Mobile at 113,944 (2.8% higher), the AMD Radeon Pro Vega II at 109,617 (1.0% lower), and the AMD Radeon Pro W6600X at 107,342 (3.2% lower). This cluster of scores within a 6.4% band shows that the Radeon PRO W7900 performs in line with high-end workstation GPUs from both vendors. The NVIDIA card's nearest rivals are the Intel Arc Pro B60 at 3,182 (3.4% higher), the NVIDIA Quadro P1000 at 3,163 (2.8% higher), the NVIDIA GeForce 820A at 2,983 (3.1% lower), and the NVIDIA GeForce GTX 860M at 2,967 (3.6% lower). This cluster sits within a 7.0% band and includes older, lower-tier mobile and entry-level desktop parts.

The largest wins come from the AMD side. In Geekbench Vulkan, the AMD card scores 137,070, which is 52,691 points higher than its own OpenCL score of 84,379. That 62.4% gap between its two recorded tests indicates the RDNA 3.0 architecture handles Vulkan workloads more efficiently than OpenCL in this configuration. The NVIDIA card's single score of 3,075 in 3DMark Steel Nomad DX12 cannot be compared to any other NVIDIA result in this pairing. The AMD card's FP32 compute of 61.32 TFLOPS is 5.04 TFLOPS higher than the NVIDIA card's 56.28 TFLOPS, a 9.0% advantage.
