Architecture Differences

The two cards diverge sharply in their underlying chip designs. AMD’s Navi 31 uses RDNA 3.0 with a chiplet-based approach codenamed Plum Bonito, belonging to the Radeon Pro Navi (Navi III Series) generation. NVIDIA’s GB202 uses Blackwell 2.0, part of the GeForce 50-series generation. The transistor counts reveal the scale difference: NVIDIA packs 92,200 million transistors, while AMD places 57,700 million on its die. The die sizes follow suit, with NVIDIA at 750 mm² and AMD at 529 mm², yielding transistor densities of 122.9M per mm² for NVIDIA and 109.1M per mm² for AMD.

Shader and fixed-function units also differ significantly. The RTX 5090 SE carries 14,080 shading units, 440 TMUs, 160 ROPs, 110 RT cores, and 440 tensor cores. The Radeon PRO W7900D has 6,144 shading units, 384 TMUs, 192 ROPs, and 96 RT cores, with no tensor core count listed. This means NVIDIA has more than double the shading units and a higher RT core count, while AMD has more ROPs. The absence of tensor cores on the AMD side points to different workload priorities, with NVIDIA’s architecture explicitly including dedicated AI acceleration hardware.

Clock behavior further separates them. The RTX 5090 SE runs at a 1740 MHz base and 2377 MHz boost, while the Radeon PRO W7900D sits at 1327 MHz base and 2156 MHz boost. Memory clocks differ as well, with AMD at 2250 MHz (18 Gbps effective) and NVIDIA at 1750 MHz (28 Gbps effective). The memory types reflect this: GDDR6 for AMD versus GDDR7 for NVIDIA.

The process nodes are identical (5 nm at TSMC), but the architectural implementations are distinct. NVIDIA’s Blackwell 2.0 uses a monolithic GB202 die, while AMD’s RDNA 3.0 uses the Navi 31 chip with a chiplet design (Plum Bonito codename). Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so the API feature set is equivalent, but the hardware paths differ in core layout and specialized units.

Head-to-Head Benchmarks

The recorded benchmark data shows no head-to-head results in the database, and neither card has an average benchmark score above zero. The percentileVsAllGpus field places both at 50, indicating they sit in the middle of the database’s GPU distribution, though this is a relative measure without raw scores to compare. Without benchmark numbers, the analysis must rely on the specification-derived throughput metrics.

In raw compute, the RTX 5090 SE delivers 66.94 TFLOPS FP32, which is approximately 26% higher than the Radeon PRO W7900D’s 52.99 TFLOPS. The texture rate follows the same pattern: NVIDIA achieves 1,045.9 GTexel/s versus AMD’s 827.9 GTexel/s, a margin of about 26%. The pixel rate, however, favors AMD at 414.0 GPixel/s compared to NVIDIA’s 380.3 GPixel/s, a difference of roughly 9% in AMD’s favor. This suggests AMD’s higher ROP count (192 versus 160) helps in fill-rate-bound scenarios.

Memory bandwidth is a clear NVIDIA advantage. The RTX 5090 SE’s 1.34 TB/s exceeds AMD’s 864.0 GB/s by approximately 55%, driven by GDDR7’s higher 28 Gbps effective speed versus GDDR6’s 18 Gbps. The memory capacity reverses this: AMD offers 48 GB, double NVIDIA’s 24 GB, which matters for large datasets that exceed 24 GB.

The RT core counts favor NVIDIA (110 versus 96), and the presence of 440 tensor cores gives NVIDIA a dedicated path for AI workloads that AMD lacks entirely. The shading unit gap (14,080 versus 6,144) is the largest single-unit difference, more than double, which likely translates to substantial advantages in shader-heavy computations. Clock speeds also favor NVIDIA at boost (2377 MHz versus 2156 MHz), though AMD’s base clock is lower at 1327 MHz versus 1740 MHz.

Specification Differences

The two cards differ in nearly every measurable field. Memory size: 48 GB versus 24 GB. Memory type: GDDR6 versus GDDR7. Bandwidth: 864.0 GB/s versus 1.34 TB/s. Shading units: 6,144 versus 14,080.

Power and physical specs also diverge. TDP: 295 W versus 500 W. Slot width: triple-slot versus dual-slot. Power connectors: 2x 8-pin versus 1x 16-pin. Suggested PSU: 600 W versus 900 W. Dimensions: the AMD card is 280 mm long, 110 mm tall, and 51 mm wide; the NVIDIA card is 267 mm long, 111 mm tall, and 40 mm wide. Bus interface: PCIe 4.0 x16 versus PCIe 5.0 x16. Display outputs: AMD has 3x DisplayPort 2.1 and 1x mini-DisplayPort 2.1; NVIDIA has 1x HDMI 2.1b and 3x DisplayPort 2.1b.

Chip details differ as well. Transistors: 57,700 million versus 92,200 million. Die size: 529 mm² versus 750 mm². Transistor density: 109.1M per mm² versus 122.9M per mm². Base clock: 1327 MHz versus 1740 MHz. Boost clock: 2156 MHz versus 2377 MHz. Memory clock: 2250 MHz (18 Gbps effective) versus 1750 MHz (28 Gbps effective). Both share the same 5 nm TSMC process, DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 support. Release dates differ: 2025-09-24 for AMD and 2025-12-31 for NVIDIA. The RTX 5090 SE has a launch MSRP of 1,499 USD; the AMD card has no listed MSRP.

Where Each One Wins

The Radeon PRO W7900D wins on memory capacity with 48 GB, exactly double the RTX 5090 SE’s 24 GB. This makes it the stronger choice for workloads that need to hold very large datasets on the GPU, such as high-resolution rendering scenes or large simulation grids that exceed 24 GB. The AMD card also has a pixel rate advantage at 414.0 GPixel/s versus 380.3 GPixel/s, plus a lower TDP of 295 W versus 500 W, which reduces system power requirements and allows for a smaller 600 W PSU recommendation. The triple-slot cooler with two 8-pin connectors is a conventional layout that fits many existing power supplies without adapter needs. The mini-DisplayPort 2.1 output adds a compact display option not present on the NVIDIA card.

The RTX 5090 SE wins on raw compute density. Its 66.94 TFLOPS FP32 is about 26% higher than AMD’s 52.99 TFLOPS, and the same margin appears in texture rate (1,045.9 GTexel/s versus 827.9 GTexel/s). Memory bandwidth is the largest relative win: 1.34 TB/s versus 864.0 GB/s, a 55% advantage that benefits data-intensive tasks. The 440 tensor cores give it a hardware path for AI and machine learning inference that the AMD card cannot match. The 110 RT cores outnumber AMD’s 96, and the 14,080 shading units more than double AMD’s 6,144. The PCIe 5.0 x16 interface doubles the bus bandwidth available on the AMD card’s PCIe 4.0 x16. The dual-slot form factor is more compact in width (40 mm versus 51 mm), and the single 16-pin connector simplifies cable management. The HDMI 2.1b output provides a direct connection for consumer displays that AMD lacks.

The Verdict

The data points to two distinct use cases. The Radeon PRO W7900D is the choice for memory-bound professional workloads where 48 GB of GDDR6 capacity is essential. The pixel rate advantage and lower 295 W TDP also make it suitable for fill-rate-heavy rendering tasks and systems with modest power budgets. The absence of tensor cores and the lower FP32 throughput mean it is not optimized for AI inference or high-throughput compute.

The RTX 5090 SE is the choice for compute-bound and AI-oriented workloads. Its 66.94 TFLOPS FP32, 1.34 TB/s memory bandwidth, and 440 tensor cores give it clear advantages in shader-heavy applications, large data transfers, and neural network inference. The higher 500 W TDP and 900 W PSU requirement are acceptable trade-offs for the performance gains. The 24 GB memory capacity is sufficient for many tasks but will be limiting for datasets that exceed that size.

Benchmark results are not available in the database for either card, so the comparison rests on specification-derived metrics. The percentileVsAllGpus value of 50 for both indicates they occupy similar relative positions in the database, but without average benchmark scores, the performance ranking is inferred from throughput rates. Users who need maximum memory should select the AMD card; users who need maximum compute and AI capabilities should select the NVIDIA card. The 2025-12-31 release date for the RTX 5090 SE and 2025-09-24 for the Radeon PRO W7900D place the NVIDIA card later in the product cycle, but both remain in active production.
