AMD Radeon Pro Vega 48 vs NVIDIA Quadro RTX 6000 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between these two workstation cards. In Geekbench OpenCL, the NVIDIA Quadro RTX 6000 scores 74,179 against the AMD Radeon Pro Vega 48's 53,757, a 38% advantage for NVIDIA. That is not a marginal lead; it is a full tier of compute performance separating the two.

The Vulkan results tell an even more dramatic story. The Quadro RTX 6000 posts 129,564, while the Radeon Pro Vega 48 manages only 57,653. That translates to a 124.7% delta, meaning the NVIDIA card more than doubles the AMD card's Vulkan throughput. If your workload leans on Vulkan compute or modern graphics APIs, the Quadro is not just faster, it is in a different category entirely.

Across the two shared benchmark tests, NVIDIA wins both. The average benchmark score for the Quadro RTX 6000 sits at 101,872, while the Radeon Pro Vega 48 averages 60,140. That is roughly a 69% higher average score for NVIDIA. The percentile rankings reinforce this: the Quadro RTX 6000 sits at the 94th percentile of all GPUs, while the Radeon Pro Vega 48 lands at the 88th percentile.

Looking at the nearest rivals in the database provides context. The Quadro RTX 6000's average score is 4.5% ahead of the AMD Radeon RX 7900M and 4.9% ahead of the AMD Radeon Pro VII. It trails the AMD Radeon Pro Vega II Duo by 4.6% and the AMD Radeon Pro W6600X by 5.1%. For the Radeon Pro Vega 48, the competition is tighter: it sits 0.3% behind the Intel Arc Pro A60 and the NVIDIA GeForce RTX 4090, while leading the AMD Radeon PRO V710 by 2.5% and the NVIDIA P102-100 by 2.8%. The Vega 48 is essentially in a dead heat with those mid-range rivals, whereas the Quadro RTX 6000 is punching near the top of the database.

Architecture Differences

The underlying silicon tells a story of two very different design philosophies. The NVIDIA Quadro RTX 6000 uses the TU102 chip built on Turing architecture, fabricated on a 12 nm process at TSMC. That chip packs 18,600 million transistors onto a 754 mm² die, giving a transistor density of 24.7 million per mm². The AMD Radeon Pro Vega 48 uses the Vega 10 chip, built on GCN 5.0 architecture, manufactured on a 14 nm process at GlobalFoundries. It contains 12,500 million transistors on a 495 mm² die, with a slightly higher transistor density of 25.3 million per mm².

The NVIDIA card is the larger, more complex chip. It carries 4,608 shading units, 288 texture mapping units, and 96 raster output pipelines. It also includes 72 RT cores and 576 tensor cores, features that are entirely absent from the AMD part. The Radeon Pro Vega 48 has 3,072 shading units, 192 TMUs, and 64 ROPs, with no RT or tensor core equivalents listed. Those RT and tensor cores are why the Quadro RTX 6000 can handle ray tracing and AI inference workloads that the Vega 48 simply cannot accelerate in hardware.

Memory architectures diverge sharply as well. The Quadro RTX 6000 uses 24 GB of GDDR6 on a 384-bit bus, delivering 672.0 GB/s of bandwidth. The Radeon Pro Vega 48 uses 8 GB of HBM2 on a 2048-bit bus, but only achieves 402.4 GB/s. The NVIDIA card has three times the capacity and 67% more bandwidth. The memory clock situation also differs: the Quadro runs at 1750 MHz (14 Gbps effective), while the Vega 48 memory runs at 786 MHz (1572 Mbps effective). The HBM2's wide bus partially compensates, but not enough to close the gap.

The process nodes tell a tale of timing. NVIDIA's 12 nm Turing was designed to be a feature-rich flagship, while AMD's 14 nm Vega was a more power-conscious design. The Quadro RTX 6000 has a 260 W TDP and requires a dual-slot cooler with 1x 6-pin plus 1x 8-pin power connectors, plus a 600 W suggested PSU. The Radeon Pro Vega 48 is an integrated graphics processor (IGP) with no power connectors and no TDP listed, designed for portable devices with display output dependent on the host system.

The Verdict

The data points to one clear conclusion: if you need raw compute performance, the NVIDIA Quadro RTX 6000 is the superior choice. It wins both head-to-head benchmarks, holds a 38% OpenCL lead and a 124.7% Vulkan lead, and sits 6 percentage points higher in the global GPU percentile ranking. For any professional workload that stresses the GPU, the Quadro is the one to pick.

However, the Radeon Pro Vega 48 is not without a purpose. Its IGP form factor, lack of power connectors, and portable-device-dependent display outputs indicate it was built for a specific niche: integrated graphics in Apple Mac Pro systems. If your system requires that form factor, the Vega 48 is the only option that fits, regardless of the performance gap. The database shows it trades blows with mid-range discrete cards like the Intel Arc Pro A60 and NVIDIA GeForce RTX 4090, so it is not a weak part, it is simply a different class of product.

Choose the Quadro RTX 6000 for maximum compute throughput, ray tracing, tensor operations, and high-bandwidth memory. Choose the Radeon Pro Vega 48 only if you are constrained to an IGP form factor and need macOS compatibility with Metal API support, where it scores 69,010 in Geekbench Metal.

Q: Does the Radeon Pro Vega 48 support ray tracing hardware?

A: No. The database lists no RT cores for the Vega 48. The Quadro RTX 6000 includes 72 RT cores and 576 tensor cores for those workloads.

Q: What is the average benchmark score difference?

A: The Quadro RTX 6000 averages 101,872 across recorded tests, while the Radeon Pro Vega 48 averages 60,140. NVIDIA's card sits at the 94th percentile of all GPUs, the AMD card at the 88th.

Q: Can the Radeon Pro Vega 48 be installed in a standard desktop tower?

A: The database lists it as an IGP (integrated graphics processor) with no power connectors and portable-device-dependent display outputs. It is not designed for a standard expansion slot. The Quadro RTX 6000 is a dual-slot card needing 1x 6-pin plus 1x 8-pin power.

Q: Which card supports newer DirectX features?

A: The Quadro RTX 6000 supports DirectX 12 Ultimate (12_2), while the Radeon Pro Vega 48 supports DirectX 12 (12_1). NVIDIA also lists Vulkan 1.4 support versus AMD's 1.3.

Where Each One Wins

The NVIDIA Quadro RTX 6000 wins every benchmark where both cards are measured. In OpenCL compute, the 38% lead means it is the clear choice for general-purpose GPU computing, simulations, and rendering that scales with raw FP32 throughput. Its 16.31 TFLOPS versus 7.373 TFLOPS is a direct 2.2x advantage in single-precision math. For Vulkan-based applications, the 124.7% margin makes it the only sensible option for games, real-time visualization, or any Vulkan compute workload. The 72 RT cores and 576 tensor cores give it capabilities in ray-traced rendering and AI inference that the Vega 48 cannot match at all.

The Radeon Pro Vega 48's wins are more situational. Its IGP form factor and lack of external power connectors mean it can be integrated into portable or compact systems where a dual-slot 260 W card simply cannot fit. The database shows it is the only option for that form factor in this comparison. Its Metal benchmark score of 69,010 is a data point for macOS environments that rely on Metal API, which the NVIDIA card does not list. The Vega 48 also matches the performance of mid-range cards like the Intel Arc Pro A60 and NVIDIA GeForce RTX 4090 within 0.3%, so it is not a weak performer for its class, it just is not in the Quadro RTX 6000's league.

The launch MSRP for the Quadro RTX 6000 is 6,299 USD, which reflects its flagship positioning. The Radeon Pro Vega 48 has no listed launch MSRP, consistent with its role as an integrated component rather than a standalone retail card. If your project demands maximum compute and modern feature support, the Quadro RTX 6000 is the data-backed winner. If you need an integrated GPU for a specific portable Mac system, the Vega 48 is the only product that fits that slot.
