AMD Radeon Pro Vega 64X vs NVIDIA RTX 6000 Ada Generation Comparison

Head-to-Head Benchmarks

The recorded data contains exactly one directly comparable benchmark between these two workstation cards: Geekbench OpenCL. In that test, the NVIDIA RTX 6000 Ada Generation scores 311,629 points, while the AMD Radeon Pro Vega 64X scores 78,467 points. The delta is a massive 297.1% in favor of the NVIDIA card. To put that in perspective, the RTX 6000 Ada delivers roughly four times the OpenCL compute performance of the Vega 64X. This is not a marginal win; it is a generational gap expressed in raw benchmark numbers.

The NVIDIA card's average benchmark score across all recorded tests is 287,237, which places it in the 99th percentile of all GPUs in the database. The AMD card's average benchmark score is 80,959, placing it in the 92nd percentile. While both are high-performing cards relative to the entire GPU landscape, the absolute gap between them is enormous. The RTX 6000 Ada's average score is approximately 3.5 times higher than the Vega 64X's average, confirming that the single head-to-head result is representative of their overall performance separation.

Looking at the nearest rivals for the RTX 6000 Ada, the data shows it sits in a competitive cluster. It is 1.1% ahead of the NVIDIA L40 (284,111 average score), 2.9% behind the NVIDIA L40S (295,763), and 9.7% behind the AMD Instinct MI300X (317,994). It is 14.4% ahead of the NVIDIA L20 (251,147). This indicates that while the RTX 6000 Ada is not the absolute fastest accelerator in its tier, it is within striking distance of the top contenders and comfortably outperforms lower-tier workstation offerings.

For the AMD Radeon Pro Vega 64X, the nearest rival data tells a different story. It is 1.3% behind the AMD Radeon PRO W6600 (81,995 average score), 1.4% ahead of the NVIDIA GeForce RTX 5090 (79,842), 1.7% ahead of the NVIDIA Tesla P100 PCIe 16 GB (79,605), and 2.0% ahead of the NVIDIA Tesla P100 PCIe 12 GB (79,396). The Vega 64X is essentially locked in a tight battle with these cards, with all deltas within a 3.3 percentage point range. This suggests that in its own performance tier, the Vega 64X is competitive but not dominant.

The head-to-head result is unambiguous. The RTX 6000 Ada Generation wins the only directly comparable benchmark, and the win is by a factor of nearly four. The wins tally in the database shows 1 win for NVIDIA and 0 for AMD. There is no benchmark in the record where the AMD card comes out ahead.

Architecture Differences

The two cards come from different manufacturing generations and design philosophies. The NVIDIA RTX 6000 Ada Generation uses the AD102 chip built on a 5 nm process at TSMC. It packs 76,300 million transistors onto a 609 mm² die, giving a transistor density of 125.3 million per mm². The AMD Radeon Pro Vega 64X uses the Vega 10 chip built on a 14 nm process at GlobalFoundries. It contains 12,500 million transistors on a 495 mm² die, for a density of 25.3 million per mm². The process node difference is stark: 5 nm versus 14 nm, which explains a large part of the performance and efficiency gap.

The architecture families are also completely different. NVIDIA uses Ada Lovelace, the successor to Workstation Ampere, and the predecessor to Blackwell PRO W. AMD uses GCN 5.0, part of the Radeon Pro Mac generation. The NVIDIA card belongs to the GeForce 60-series workstation lineup, while the AMD card is in the Vega Series for Mac systems.

Core counts differ by a wide margin. The RTX 6000 Ada has 18,176 shading units, 568 texture mapping units, 192 render output units, 142 ray tracing cores, and 568 tensor cores. The Vega 64X has 4,096 shading units, 256 TMUs, and 64 ROPs, with no ray tracing cores and no tensor cores listed. This means the NVIDIA card has over 4.4 times the shading units, 2.2 times the TMUs, and 3 times the ROPs. The absence of dedicated RT and tensor hardware on the AMD card is a fundamental architectural difference that affects workloads relying on ray tracing or AI acceleration.

Memory subsystems are also divergent. The RTX 6000 Ada has 48 GB of GDDR6 memory on a 384-bit bus, yielding 960.0 GB/s of bandwidth. The Vega 64X has 16 GB of HBM2 memory on a 2048-bit bus, yielding 512.0 GB/s of bandwidth. While the Vega 64X uses a much wider bus, the older HBM2 standard and lower effective clock speed result in roughly half the bandwidth. The NVIDIA card also has triple the memory capacity.

Clock speeds show an interesting inversion. The AMD card has a higher base clock at 1250 MHz versus 915 MHz for NVIDIA, and a higher boost clock at 1468 MHz versus 2505 MHz for NVIDIA. However, the NVIDIA boost clock is substantially higher, reaching 2505 MHz, which contributes to its massive compute throughput advantage.

Compute rates confirm the architectural gap. The RTX 6000 Ada delivers 91.06 TFLOPS of FP32 and 91.06 TFLOPS of FP16 (1:1 ratio). The Vega 64X delivers 12.03 TFLOPS of FP32 and 24.05 TFLOPS of FP16 (2:1 ratio). The NVIDIA card is roughly 7.6 times faster in FP32 and 3.8 times faster in FP16. Pixel rate is 481.0 GPixel/s for NVIDIA versus 93.95 GPixel/s for AMD, and texture rate is 1,422.8 GTexel/s versus 375.8 GTexel/s.

The Verdict

The data points to a clear and decisive winner for almost any compute workload. The NVIDIA RTX 6000 Ada Generation outperforms the AMD Radeon Pro Vega 64X by 297.1% in the only direct benchmark available. Its average benchmark score of 287,237 is 3.5 times higher than the Vega 64X's 80,959. The NVIDIA card sits in the 99th percentile of all GPUs, while AMD sits in the 92nd.

The RTX 6000 Ada also has significant architectural advantages: more shading units, dedicated ray tracing and tensor cores, triple the memory capacity, nearly double the bandwidth, and a much smaller manufacturing process. The Vega 64X is a 2019-era Mac-specific part with no direct successor listed, while the RTX 6000 Ada is part of an active workstation lineage with a successor already named (Blackwell PRO W).

For users who need maximum compute performance, ray tracing capability, or large memory capacity for AI or rendering workloads, the RTX 6000 Ada is the obvious choice based on the recorded measurements. The Vega 64X is competitive within its own tier, as shown by its near-identical scores to the Radeon PRO W6600 and GeForce RTX 5090, but it is not in the same class as the RTX 6000 Ada.

The one area where the Vega 64X has a potential advantage is in its integrated form factor. It is an IGP with no power connectors and no external dimensions listed, meaning it is designed for portable or Mac systems where discrete card installation is not possible. The RTX 6000 Ada is a dual-slot card at 267 mm long and 112 mm high, requiring a 16-pin connector and a 700 W PSU.
