AMD Radeon Pro Vega 64 vs NVIDIA RTX 6000D Comparison

Where Each One Wins

The recorded data splits this comparison into two very different use cases. The NVIDIA RTX 6000D dominates in every measured head-to-head contest, while the AMD Radeon Pro Vega 64 shows its strength only in legacy compute environments where its specific API support matters. Across the entire benchmark suite, the RTX 6000D wins 1 out of 1 shared tests, leaving the Vega 64 with zero direct wins.

The RTX 6000D is built for modern, high-throughput workloads. Its Geekbench OpenCL score of 388,405 dwarfs the Vega 64's 71,094 in the same test, a 446.3% advantage. This is not a marginal gap; it represents a generational leap in raw compute density. The 6000D also holds a 98th percentile ranking among all GPUs, whereas the Vega 64 sits at the 91st percentile. In absolute terms, the 6000D's average benchmark score of 195,964 is roughly 2.7 times higher than the Vega 64's 72,379.

For the Vega 64, the wins are narrower and more situational. Its Geekbench Metal score of 71,868 and Vulkan score of 74,174 are not compared directly against the 6000D in the database, since the 6000D lacks those specific test entries. However, the Vega 64's OpenCL result of 71,094 shows it remains competitive with its own nearest rivals, sitting within 2.2% of the AMD Radeon RX 6600 LE and 0.4% of the NVIDIA TITAN X Pascal. The data suggests the Vega 64 is still relevant for macOS-oriented or legacy API workloads, but it cannot challenge the 6000D in any shared metric.

Architecture Differences

The architectural gap here is vast, and it explains nearly every benchmark delta. The RTX 6000D uses NVIDIA's Blackwell 2.0 architecture on a 5 nm TSMC process, packing 92,200 million transistors into a 750 mm² die. The Vega 64 relies on AMD's GCN 5.0 architecture on a 14 nm GlobalFoundries process, with just 12,500 million transistors across a 495 mm² die. That is a 7.4x difference in transistor count and a 4.9x difference in transistor density (122.9M per mm² versus 25.3M per mm²).

The 6000D features 19,968 shading units, 624 texture mapping units, and 192 render output units. It also includes 156 ray tracing cores and 624 tensor cores, hardware that the Vega 64 simply does not have. The Vega 64 offers 4,096 shading units, 256 TMUs, and 64 ROPs, with no dedicated ray tracing or tensor hardware. This explains why the 6000D achieves 97.04 TFLOPS FP32 and 97.04 TFLOPS FP16 (1:1 ratio), while the Vega 64 manages only 11.06 TFLOPS FP32 and 22.12 TFLOPS FP16 (2:1 ratio).

Memory architecture also diverges sharply. The 6000D uses 84 GB of GDDR7 on a 448-bit bus, delivering 1.40 TB/s of bandwidth. The Vega 64 uses 16 GB of HBM2 on a 2048-bit bus, delivering 402.4 GB/s. Interestingly, the Vega 64's wider bus (2048-bit versus 448-bit) cannot compensate for the older, slower memory technology. The 6000D's memory clock of 1560 MHz (25 Gbps effective) is roughly double the Vega 64's 786 MHz (1572 Mbps effective), and that bandwidth advantage is decisive for large dataset workloads.

Head-to-Head Benchmarks

The only shared benchmark in the database is Geekbench OpenCL, and the results are lopsided. The RTX 6000D scores 388,405, while the Vega 64 scores 71,094. The 446.3% delta means the 6000D is more than 5.4 times faster in this compute test. To put that in perspective, the Vega 64's score is closer to the 6000D's nearest rival (the NVIDIA Tesla V100S PCIe 32 GB at 194,415) than it is to the 6000D itself, but even that comparison is misleading because the 6000D leads the V100S by 0.8% and the Vega 64 trails the V100S by 63%.

The 6000D's OpenCL result also shows how far ahead it is of its own competition. It beats the NVIDIA A100 SXM4 40 GB by 4.7% and the NVIDIA RTX 5000 Ada Generation by 6.1%, while trailing only the A100 PCIe 80 GB by 5.4%. The Vega 64, by contrast, sits in a much tighter cluster with its rivals: it leads the TITAN X Pascal by 0.4% and the RX 6650M by 0.9%, but trails the Vega Frontier Edition by 1.4%. This indicates the Vega 64 is at parity with mid-range GPUs from several generations ago, while the 6000D operates in a performance tier that has no direct competitor in the database.

Pixel and texture rates tell the same story. The 6000D produces 466.6 GPixel/s and 1,516.3 GTexel/s, versus 86.40 GPixel/s and 345.6 GTexel/s for the Vega 64. Those are 5.4x and 4.4x advantages, respectively, and they directly impact rasterization-heavy tasks like 3D rendering and real-time visualization.
