AMD Radeon Pro Vega 64X vs AMD Radeon Pro WX 9100 Comparison

The AMD Radeon Pro Vega 64X and the AMD Radeon Pro WX 9100 are both professional workstation GPUs built on the same fundamental architecture, yet the benchmark data reveals a clear performance hierarchy between them. Across the two shared tests, the Vega 64X secures decisive victories, while the WX 9100 counters with a higher boost clock and a lower power draw, creating a nuanced comparison that goes beyond raw speed.

Where Each One Wins

The performance split is unambiguous: the AMD Radeon Pro Vega 64X wins both head-to-head benchmark comparisons, establishing itself as the faster card in compute-intensive workloads. In Geekbench Metal, the Vega 64X scores 83,450 against the WX 9100’s 71,319, a 17% advantage. In OpenCL, the gap widens slightly to 17.8%, with scores of 78,467 and 66,605 respectively. For users prioritizing maximum compute throughput in Metal or OpenCL applications, the data points squarely at the Vega 64X.

The AMD Radeon Pro WX 9100, however, wins on physical design and integration flexibility. It is a dual-slot card with 6x mini-DisplayPort 1.4a outputs, allowing direct multi-display connectivity, while the Vega 64X is an IGP (integrated graphics processor) with portable-device-dependent outputs and no power connectors. The WX 9100 also carries a suggested PSU of 550 W and a lower TDP of 230 W, making it the more straightforward choice for a standard workstation chassis. Its 267 mm length and 111 mm height are standard dimensions for PCIe cards, whereas the Vega 64X’s slot width is listed as IGP, indicating a fundamentally different form factor.

Architecture Differences

Despite sharing the same Vega 10 chip, GCN 5.0 architecture, 14 nm process node from GlobalFoundries, and identical transistor counts of 12,500 million on a 495 mm² die, the two cards diverge in clock speeds and memory configuration. The Vega 64X operates with a base clock of 1250 MHz and a boost clock of 1468 MHz, while the WX 9100 runs slightly lower at 1200 MHz base but boosts higher to 1500 MHz. This 32 MHz boost advantage for the WX 9100 does not translate into a performance win in the benchmark data, suggesting that other factors dominate.

Memory speeds also differ. The Vega 64X runs its HBM2 at 1000 MHz (2 Gbps effective), yielding a bandwidth of 512.0 GB/s, whereas the WX 9100’s HBM2 runs at 945 MHz (1890 Mbps effective), providing 483.8 GB/s — a 28.2 GB/s deficit. Both cards have 16 GB of memory on a 2048-bit bus, so the Vega 64X’s bandwidth advantage is purely clock-driven. The shading units (4096), TMUs (256), and ROPs (64) are identical, as are the pixel rate (93.95 vs 96.00 GPixel/s) and texture rate (375.8 vs 384.0 GTexel/s) figures — the WX 9100 actually leads in those two rasterization metrics due to its higher boost clock.

Head-to-Head Benchmarks

The Geekbench Metal test shows the Vega 64X scoring 83,450 against 71,319 for the WX 9100, a 17% delta. This is the smaller of the two victories, yet it still places the Vega 64X comfortably ahead. The OpenCL test amplifies the gap, with the Vega 64X at 78,467 and the WX 9100 at 66,605, a 17.8% difference. Notably, the WX 9100 has an additional Vulkan benchmark score of 54,711 in its own record, but there is no corresponding Vulkan score for the Vega 64X in the head-to-head data, so a direct comparison on that API is not available.

The average benchmark scores further illustrate the divide. The Vega 64X averages 80,959 across its two tests, placing it in the 92nd percentile of all GPUs. The WX 9100, despite having three benchmark entries, averages only 64,212, dropping to the 89th percentile. The Vega 64X’s nearest rival is the AMD Radeon PRO W6600, which scores 81,995 on average, just 1.3% higher. The WX 9100, by contrast, sits near the NVIDIA CMP 30HX (63,842, 0.6% ahead) and the AMD Radeon RX 9060 XT LP (63,830, 0.6% ahead). This contextualizes the two AMD cards as belonging to different performance tiers, with the Vega 64X aligning with high-end compute boards like the NVIDIA RTX 5090 (79,842, 1.4% behind) and the WX 9100 competing with mid-range consumer and mining cards.

FAQ

Q: Which card has a higher boost clock?

A: The AMD Radeon Pro WX 9100 has a boost clock of 1500 MHz, compared to 1468 MHz for the AMD Radeon Pro Vega 64X.

Q: How much faster is the Vega 64X in OpenCL?

A: Yes, both use the Vega 10 chip with 12,500 million transistors on a 495 mm² die, fabricated on a 14 nm process.

The Verdict

The benchmark data is unequivocal: the AMD Radeon Pro Vega 64X is the superior performer for compute tasks. It wins both available head-to-head tests with deltas of 17% and 17.8%, and its average score of 80,959 places it in the 92nd percentile, far above the WX 9100’s 64,212 average in the 89th percentile. Users running Metal or OpenCL workloads — common in creative, scientific, and engineering applications — should choose the Vega 64X based on this evidence.

The WX 9100, however, is not without merit. Its lower TDP of 230 W, standard dual-slot form factor, and 6x mini-DisplayPort 1.4a outputs make it more adaptable for conventional workstation builds. It also has a higher boost clock of 1500 MHz and superior pixel and texture rates (96.00 GPixel/s and 384.0 GTexel/s, respectively). For a system where power efficiency, display connectivity, and physical compatibility are priorities over raw compute, the WX 9100 remains a valid choice. The data suggests a trade-off: the Vega 64X is the compute specialist, while the WX 9100 is the versatile workstation card.
