AMD Radeon RX 7900 GRE vs NVIDIA RTX PRO 4000 Blackwell Comparison

Head-to-Head Benchmarks

The recorded data shows a surprisingly balanced contest between the AMD Radeon RX 7900 GRE and the NVIDIA RTX PRO 4000 Blackwell, with NVIDIA taking 5 wins and AMD taking 4. The most dramatic swing is in Geekbench Vulkan, where the NVIDIA card delivers a 194168 score against AMD's 99850, a 48.6% deficit for the Radeon. That is a massive gap in low-level graphics API performance, suggesting the Blackwell architecture handles Vulkan workloads with substantially greater efficiency.

However, the tables turn in DirectX legacy tests. AMD wins Passmark DirectX 11 by 8.7% (300 vs 276) and Passmark DirectX 12 by 10.3% (107 vs 97). The RX 7900 GRE also takes the newer 3DMark Steel Nomad DX12 test, scoring 4814 against NVIDIA's 4648, a 3.6% advantage. This pattern implies AMD holds a lead in modern DirectX 12 workloads, while NVIDIA dominates Vulkan.

In older DirectX versions, NVIDIA shows strength: Passmark DirectX 10 goes to NVIDIA by 19.7% (173 vs 139), and DirectX 9 goes to NVIDIA by 12.4% (354 vs 310). The 2D performance also favors NVIDIA, with Passmark G2D at 1265 versus 1180, a 6.7% margin. For overall 3D rendering, NVIDIA's Passmark G3D score of 28427 edges out AMD's 27089 by 4.7%. Compute performance is nearly identical, with AMD's 15016 barely ahead of NVIDIA's 14805, a 1.4% difference.

Looking at average benchmark scores, AMD holds a notable overall advantage at 32456 versus NVIDIA's 27135. The percentile rankings confirm this: AMD sits at the 77th percentile of all GPUs, while NVIDIA ranks at the 72nd. Interestingly, AMD's nearest rivals include the AMD FirePro S10000 (0.2% ahead), AMD FirePro S9300 X2 (0.3% behind), and AMD Radeon RX 590 GME (0.4% behind). NVIDIA's nearest rivals include the AMD Radeon RX 6700 XT (1.1% behind), NVIDIA GeForce RTX 4070 Mobile (1.1% behind), and NVIDIA GeForce RTX 3090 (1.6% behind).

The Verdict

The data does not support a single clear winner. AMD wins the overall average benchmark score by a wide margin (32456 vs 27135), placing it 5 percentile points higher in the global GPU distribution. For users prioritizing DirectX 12 gaming and compute throughput, the RX 7900 GRE is the stronger choice based on its 3DMark Steel Nomad and Passmark DX12 wins.

NVIDIA's RTX PRO 4000 Blackwell counters with a decisive Vulkan advantage (48.6% ahead), superior 2D performance, and better results in legacy DirectX 9 and 10 tests. Its 24 GB of GDDR7 memory and 672.0 GB/s bandwidth exceed AMD's 16 GB GDDR6 at 576.0 GB/s, suggesting advantages in memory-heavy professional workloads.

The power envelope is another separator: NVIDIA's 140 W TDP versus AMD's 260 W means the RTX PRO 4000 delivers competitive performance at nearly half the power draw. This makes it appealing for dense workstation environments or systems with modest power delivery.

Architecture Differences

The two GPUs represent fundamentally different design philosophies. AMD's Radeon RX 7900 GRE uses the Navi 31 chip on RDNA 3.0 architecture, codenamed Plum Bonito, fabricated on a 5 nm process at TSMC. It packs 57,700 million transistors across a 529 mm² die, yielding a transistor density of 109.1M per mm². The NVIDIA RTX PRO 4000 Blackwell uses the GB203 chip on Blackwell 2.0 architecture, also on TSMC's 5 nm node, with 45,600 million transistors on a smaller 378 mm² die, achieving a higher density of 120.6M per mm².

The compute configurations diverge sharply. AMD employs 5120 shading units, 320 TMUs, and 160 ROPs, with 80 dedicated ray tracing cores. NVIDIA counters with 8960 shading units, 280 TMUs, and only 96 ROPs, plus 70 ray tracing cores and 280 tensor cores. Despite fewer shading units, AMD achieves higher raw throughput: 45.98 TFLOPS FP32 versus NVIDIA's 36.83 TFLOPS, and 91.96 TFLOPS FP16 versus NVIDIA's 36.83 TFLOPS. The FP16 ratio tells the story: AMD runs at 2:1 while NVIDIA runs at 1:1, meaning AMD's half-precision performance is double its single-precision, while NVIDIA's is identical.

Memory subsystems differ in type and width. AMD uses 16 GB of GDDR6 on a 256-bit bus, while NVIDIA uses 24 GB of GDDR7 on a narrower 192-bit bus. NVIDIA's memory clock runs at 1750 MHz (28 Gbps effective), while AMD's memory clock is 2250 MHz (18 Gbps effective). The result is higher bandwidth for NVIDIA: 672.0 GB/s versus 576.0 GB/s.

Pixel and texture rates also diverge. AMD achieves 359.2 GPixel/s and 718.4 GTexel/s, while NVIDIA manages 197.3 GPixel/s and 575.4 GTexel/s. AMD's higher ROP count and texture units explain these advantages.
