Q: Which card has more memory and what type?

A: The AMD Radeon PRO W7900 packs 48 GB of GDDR6 memory on a 384-bit bus, delivering 864.0 GB/s of bandwidth. The NVIDIA GeForce RTX 3090 Ti has 24 GB of GDDR6X memory on the same 384-bit bus, but its bandwidth is higher at 1.01 TB/s.

Q: Are these cards the same physical size?

A: No. The RTX 3090 Ti measures 336 mm in length, 140 mm in height, and 61 mm in width. The Radeon PRO W7900 is smaller at 280 mm long, 110 mm tall, and 51 mm wide. Both are triple-slot cards.

Q: What are the production statuses of these two GPUs?

A: The NVIDIA GeForce RTX 3090 Ti is end-of-life, having launched on January 26, 2022. The AMD Radeon PRO W7900 is still active in production, with a release date of May 25, 2023.

Architecture Differences

The NVIDIA GeForce RTX 3090 Ti is built on the Ampere architecture using the GA102 chip, fabricated on Samsung's 8 nm process node. The die size is 628 mm², housing 28,300 million transistors, which works out to a transistor density of 45.1 million per mm². In contrast, the AMD Radeon PRO W7900 uses the RDNA 3.0 architecture with the Navi 31 chip, codenamed "Plum Bonito," manufactured on TSMC's 5 nm node. Its die is smaller at 529 mm² but packs significantly more transistors — 57,700 million — resulting in a much higher density of 109.1 million per mm².

The compute layouts differ substantially. The RTX 3090 Ti features 10,752 shading units, 336 TMUs, and 112 ROPs, with 84 RT cores and 336 tensor cores. The Radeon PRO W7900 has fewer shading units at 6,144, but more TMUs (384) and more ROPs (192). It also has 96 RT cores, though it lacks tensor cores entirely — a key architectural distinction, as the NVIDIA card's tensor cores are absent from the AMD design.

Clock speeds favor AMD. The Radeon PRO W7900 has a base clock of 1760 MHz and a boost clock of 2495 MHz, while the RTX 3090 Ti runs at 1560 MHz base and 1860 MHz boost. The AMD card also achieves higher pixel and texture rates: 479.0 GPixel/s and 958.1 GTexel/s, respectively, versus 208.3 GPixel/s and 625.0 GTexel/s for the NVIDIA card. In raw FP32 throughput, the AMD card is ahead at 61.32 TFLOPS versus 40.00 TFLOPS for the NVIDIA card, with both offering 1:1 FP16 rates.

Memory architecture diverges too. The RTX 3090 Ti uses 24 GB of GDDR6X with 1.01 TB/s bandwidth, while the Radeon PRO W7900 uses 48 GB of GDDR6 with 864.0 GB/s bandwidth. Both run on a 384-bit bus and PCIe 4.0 x16. Display outputs differ: the NVIDIA card offers 1x HDMI 2.1 and 3x DisplayPort 1.4a, while the AMD card provides 3x DisplayPort 2.1 and 1x mini-DisplayPort 2.1. Power requirements also separate them — the RTX 3090 Ti has a 450 W TDP with a single 16-pin connector and an 850 W suggested PSU, whereas the Radeon PRO W7900 draws 295 W via two 8-pin connectors and needs only a 600 W PSU.

The Verdict

The benchmark data is unambiguous in compute workloads: the NVIDIA GeForce RTX 3090 Ti outperforms the AMD Radeon PRO W7900 in both available head-to-head tests. In Geekbench OpenCL, the NVIDIA card leads by 106.7%, and in Geekbench Vulkan, it leads by 57.3%. That pattern holds in average scores as well — the RTX 3090 Ti's 131,938 average is 19% higher than the Radeon PRO W7900's 110,725.

However, the AMD card is not without reason for selection. It offers double the memory (48 GB versus 24 GB), which matters for large datasets that exceed 24 GB. It also has a smaller physical footprint (280 mm versus 336 mm length) and a lower TDP of 295 W versus 450 W, making it easier to cool and power. The AMD card is also still in active production, while the NVIDIA card is end-of-life.

Users who prioritize raw compute performance in OpenCL and Vulkan benchmarks should choose the GeForce RTX 3090 Ti. Users who need 48 GB of VRAM, lower power draw, a smaller card, or an actively produced product should choose the Radeon PRO W7900. The RTX 3090 Ti wins on throughput; the Radeon PRO W7900 wins on capacity and efficiency.

Head-to-Head Benchmarks

The two GPUs share only two directly comparable benchmark results in the data, and the NVIDIA GeForce RTX 3090 Ti wins both decisively.

Geekbench OpenCL: The RTX 3090 Ti scores 174,441 versus the Radeon PRO W7900's 84,379. That is a 106.7% delta — the NVIDIA card more than doubles the AMD card's performance in this test. This is the single largest margin in the head-to-head comparison, and it underscores the NVIDIA card's strength in general-purpose compute workloads as measured by OpenCL.

Geekbench Vulkan: The RTX 3090 Ti again leads, scoring 215,633 against 137,070 for the Radeon PRO W7900. The 57.3% delta is substantial, though not as extreme as the OpenCL gap. The NVIDIA card's Vulkan score is notably higher than its OpenCL score, suggesting particularly strong graphics-API performance relative to the AMD card.

Beyond the direct head-to-head, the average benchmark scores reinforce the same conclusion. The RTX 3090 Ti's 131,938 average is higher than the Radeon PRO W7900's 110,725, and its nearest rivals — the NVIDIA L4 (131,072, +0.7%) and the RTX 4000 Ada Generation (135,218, -2.4%) — bracket it closely. The Radeon PRO W7900's nearest rivals include the Radeon Pro Vega II (109,617, +1%) and the RTX A5500 Mobile (113,944, -2.8%), indicating it sits in a lower performance tier.

The wins tally is 2-0 in favor of NVIDIA across the head-to-head tests. However, the Radeon PRO W7900's advantages lie outside these benchmarks: its 48 GB memory capacity, higher FP32 throughput (61.32 TFLOPS versus 40.00 TFLOPS), superior pixel and texture rates, and lower power draw. The data shows a clear trade-off — NVIDIA dominates the available compute benchmarks, while AMD counters with raw specifications that could benefit specific workloads not represented in these two tests.
