AMD Radeon Pro WX 2100 vs AMD Radeon RX 7800 XT Comparison

Where Each One Wins

The benchmark records show a clear split between these two AMD cards, though it is heavily weighted toward the newer model. The AMD Radeon RX 7800 XT wins both recorded head-to-head tests: Geekbench OpenCL and Geekbench Vulkan. In OpenCL, it scores 18290 against the Radeon Pro WX 2100's 8536, a 114.3% advantage. In Vulkan, the gap widens dramatically: 54228 versus 10770, a 403.5% lead.

There is no benchmark category where the Radeon Pro WX 2100 emerges victorious in our measurements. The database records two wins for the RX 7800 XT and zero for the Pro WX 2100 in their direct comparisons. However, the Pro WX 2100 does hold its own within its own peer group. Its average benchmark score of 9653 places it within 0.6% of the NVIDIA Tesla C2070 (9716), 0.1% ahead of the NVIDIA GeForce GTX 960M (9645), and 0.2% ahead of the NVIDIA Quadro K5000 (9637). It trails the NVIDIA Quadro P4000 (9665) by only 0.1%.

The RX 7800 XT, by contrast, sits at the 51st percentile among all GPUs in the database, with an average benchmark score of 11627. Its nearest rivals are tightly packed: the NVIDIA GeForce GTX 1660 (11680, a 0.5% gap), the AMD Radeon RX 6500 XT (11842, a 1.8% gap), the AMD Radeon Pro 5500M (11528, a 0.9% gap), and the NVIDIA Tesla K20c (11479, a 1.3% gap). The Pro WX 2100 sits at the 46th percentile, a modest but measurable separation in overall standing.

The use-case split is therefore straightforward: the RX 7800 XT is the compute and graphics powerhouse, while the Pro WX 2100 is a low-power professional card whose strengths lie in efficiency and form factor rather than raw performance. In every measured workload, the newer card dominates.

Architecture Differences

The architectural gap between these two GPUs spans nearly every fundamental design parameter. The RX 7800 XT uses the Navi 32 chip built on RDNA 3.0 architecture, manufactured on a 5 nm process at TSMC. The Pro WX 2100 uses the Lexa chip based on GCN 4.0 architecture, fabricated on a 14 nm process at GlobalFoundries. The process node difference alone accounts for substantial efficiency and density disparities.

Transistor counts tell the story clearly. The RX 7800 XT packs 28,100 million transistors on a 346 mm² die, yielding a transistor density of 81.2M per mm². The Pro WX 2100 has 2,200 million transistors on a 103 mm² die, for a density of 21.4M per mm². That is a 13x difference in raw transistor count and nearly a 4x difference in density.

The RX 7800 XT belongs to the Radeon RX 7000 series, generation Navi III (RX 7000), with the codename Wheat Nas. The Pro WX 2100 comes from the Radeon Pro Polaris generation (WX x100) with no recorded codename. The RX 7800 XT's predecessor is Navi II and its successor is Navi IV. The Pro WX 2100's predecessor is Radeon Pro GCN and its successor is Radeon Pro Vega.

Compute resources differ enormously. The RX 7800 XT has 3840 shading units, 240 texture mapping units, and 96 render output units. It also includes 60 ray tracing cores. The Pro WX 2100 has 512 shading units, 32 TMUs, and 16 ROPs, with no ray tracing cores. The RX 7800 XT supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Pro WX 2100 supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3. The newer card has a higher API ceiling.

Memory architecture is equally divergent. The RX 7800 XT uses 16 GB of GDDR6 memory on a 256-bit bus, with 624.1 GB/s bandwidth. The Pro WX 2100 uses 2 GB of GDDR5 memory on a 64-bit bus, with 48.00 GB/s bandwidth. Clock speeds differ as well: the RX 7800 XT has a base clock of 1295 MHz, a boost clock of 2430 MHz, and a game clock of 2124 MHz. The Pro WX 2100 has a base clock of 925 MHz and a boost clock of 1219 MHz.

Head-to-Head Benchmarks

The two recorded head-to-head tests show overwhelming dominance by the RX 7800 XT. In Geekbench OpenCL, the RX 7800 XT scores 18290 against the Pro WX 2100's 8536. That is a 114.3% advantage, meaning the newer card more than doubles the older one's score. In Geekbench Vulkan, the RX 7800 XT scores 54228 against 10770, a 403.5% lead. The Vulkan result is particularly lopsided, reflecting both the architectural generational leap and the RX 7800 XT's much larger compute resource pool.

Beyond these direct comparisons, the RX 7800 XT also has a broader benchmark profile. It records scores in PassMark DirectX 9 (304), DirectX 10 (121), DirectX 11 (249), and DirectX 12 (93), along with PassMark G2D (1177), G3D (24176), and GPU Compute (13473). It also has a 3DMark Steel Nomad DX12 score of 4157. The Pro WX 2100 has no recorded scores in these additional tests in the database, limiting direct comparison to the two Geekbench entries.

The average benchmark scores place the RX 7800 XT at 11627, which is roughly 20% higher than the Pro WX 2100's 9653. However, the percentile rankings tell a slightly different story: the RX 7800 XT sits at the 51st percentile, while the Pro WX 2100 sits at the 46th. The gap in percentile is smaller than the gap in raw scores, suggesting that the Pro WX 2100's performance, while lower, is not anomalously weak relative to the broader GPU landscape.

The delta percentages in the nearest rivals lists reinforce this. The RX 7800 XT's closest competitor, the NVIDIA GeForce GTX 1660, is only 0.5% away in average score. The Pro WX 2100's closest competitor, the NVIDIA GeForce GTX 960M, is just 0.1% away. Both cards are well-positioned within their respective performance tiers.
