AMD Radeon Pro 580 vs AMD Radeon RX 7900 GRE Comparison

FAQ

Q: Which GPU has the higher average benchmark score?

A: The AMD Radeon Pro 580 records an average benchmark score of 40318, while the AMD Radeon RX 7900 GRE averages 32456. The Pro 580 leads by roughly 24% in this aggregate metric, though the RX 7900 GRE wins the two shared head-to-head tests.

Q: How do the two cards compare in Geekbench OpenCL?

A: The RX 7900 GRE scores 175758 versus 38457 for the Pro 580, a delta of -78.1% from the perspective of the older card. This makes the RX 7900 GRE about 4.6 times faster in OpenCL compute workloads.

Q: What is the process node difference between the two architectures?

A: The Pro 580 uses a 14 nm process at GlobalFoundries, while the RX 7900 GRE is built on a 5 nm process at TSMC. The RX 7900 GRE also has a much higher transistor density, 109.1M per mm² versus 24.6M per mm².

Q: Which card supports newer DirectX features?

A: The RX 7900 GRE supports DirectX 12 Ultimate (12_2), while the Pro 580 only reaches DirectX 12 (12_0). The RX 7900 GRE also supports Vulkan 1.4 versus Vulkan 1.3 on the Pro 580.

Q: What is the memory configuration difference?

A: The Pro 580 has 8 GB of GDDR5 on a 256-bit bus with 217.0 GB/s bandwidth. The RX 7900 GRE doubles capacity to 16 GB of GDDR6, also on a 256-bit bus, but with 576.0 GB/s bandwidth, a 2.65 times increase.

Q: Which card has a higher pixel rate?

A: The RX 7900 GRE reaches 359.2 GPixel/s, while the Pro 580 manages 38.40 GPixel/s. The RX 7900 GRE is approximately 9.4 times faster in pixel throughput.

Architecture Differences

The two GPUs represent entirely different design generations from AMD. The Pro 580 uses the Ellesmere chip with GCN 4.0 architecture, a 14 nm process from GlobalFoundries, and packs 5,700 million transistors on a 232 mm² die. The RX 7900 GRE uses Navi 31 with RDNA 3.0 architecture, a 5 nm process from TSMC, and integrates 57,700 million transistors on a 529 mm² die. That is a tenfold increase in transistor count and a die size more than double, resulting in a transistor density of 109.1M per mm² versus 24.6M per mm².

The compute layout diverges sharply. The Pro 580 has 2304 shading units, 144 texture mapping units, and 32 ROPs. The RX 7900 GRE more than doubles the shading units to 5120, has 320 TMUs, and 160 ROPs. The RX 7900 GRE also introduces 80 ray tracing cores, a feature entirely absent from the GCN-based Pro 580. The FP32 throughput tells the story: 5.530 TFLOPS for the Pro 580 versus 45.98 TFLOPS for the RX 7900 GRE. The RX 7900 GRE also doubles its FP16 rate to 91.96 TFLOPS with a 2:1 ratio, whereas the Pro 580 runs FP16 at the same 5.530 TFLOPS with a 1:1 ratio.

Clock behavior differs fundamentally. The Pro 580 runs a base clock of 1100 MHz and a boost of 1200 MHz, with memory at 1695 MHz (6.8 Gbps effective). The RX 7900 GRE has a base of 1287 MHz, a boost of 2245 MHz, a game clock of 1880 MHz, and memory at 2250 MHz (18 Gbps effective). The memory subsystem also diverges: 8 GB GDDR5 versus 16 GB GDDR6, both on a 256-bit bus, but bandwidth jumps from 217.0 GB/s to 576.0 GB/s.

The bus interface advances from PCIe 3.0 x16 to PCIe 4.0 x16. The RX 7900 GRE is a dual-slot card with two 8-pin power connectors and a suggested 600 W PSU, while the Pro 580 is an integrated graphics processor (IGP) with no power connectors and a 185 W TDP. Display outputs also differ: the Pro 580 relies on portable device dependent outputs, while the RX 7900 GRE offers 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C. The RX 7900 GRE measures 276 mm in length, 110 mm in height, and 51 mm in width, while the Pro 580 has no listed dimensions.

The Verdict

The data points to two very different use cases. The AMD Radeon Pro 580, released in June 2017, is end-of-life and was designed as an integrated GPU for Mac systems. Its average benchmark score of 40318 and 82nd percentile among all GPUs show it remains competitive in aggregate against much newer hardware, but its performance ceiling is low. The AMD Radeon RX 7900 GRE, released in July 2023 and still active, sits at the 77th percentile with an average score of 32456, yet it wins the shared Geekbench tests by enormous margins. The RX 7900 GRE is the clear choice for compute-heavy workloads, ray tracing, and modern API support. The Pro 580 should only be considered for legacy Mac environments or where the IGP form factor is mandatory. For anyone building a new system, the RX 7900 GRE is the only sensible pick from the data.

Head-to-Head Benchmarks

The two shared benchmark tests in the database are Geekbench OpenCL and Geekbench Vulkan. In both, the RX 7900 GRE dominates decisively. In Geekbench OpenCL, the RX 7900 GRE scores 175758 against 38457 for the Pro 580, a delta of -78.1% when viewed from the Pro 580’s side. That translates to the RX 7900 GRE delivering roughly 4.6 times the OpenCL compute performance. This gap is consistent with the raw FP32 figures, where the RX 7900 GRE achieves 45.98 TFLOPS versus 5.530 TFLOPS, an 8.3 times advantage.

In Geekbench Vulkan, the RX 7900 GRE scores 99850 versus 43285 for the Pro 580, a delta of -56.6%. The RX 7900 GRE is about 2.3 times faster in Vulkan workloads. The Pro 580’s nearest rivals include the NVIDIA GeForce RTX 5070 at -0.1% delta, the AMD Radeon Pro WX 7100 at +0.6%, and the AMD Radeon Pro 5300 at -1.4%. The RX 7900 GRE’s nearest rivals are the AMD FirePro S10000 at +0.2%, the AMD FirePro S9300 X2 at -0.3%, and the AMD Radeon RX 590 GME at -0.4%. These rival comparisons show the Pro 580 punches near the level of an RTX 5070 in average score, while the RX 7900 GRE sits in a cluster of older FirePro and RX 500-series cards, despite its much higher peak compute.

The RX 7900 GRE also has additional benchmark data not available for the Pro 580: 3DMark Steel Nomad DX12 at 4814, Passmark DirectX 10 at 139, DirectX 11 at 300, DirectX 12 at 107, DirectX 9 at 310, G2D at 1180, G3D at 27089, and GPU compute at 15016. The Pro 580 only has Geekbench Metal at 39213, OpenCL at 38457, and Vulkan at 43285. The wins tally is 2 for the RX 7900 GRE and 0 for the Pro 580 in direct comparisons. The average benchmark score difference (40318 vs 32456) favors the Pro 580 because the RX 7900 GRE’s average includes lower Passmark scores, but in the two compute-oriented tests that both cards share, the RX 7900 GRE is unequivocally faster. The percentile rankings, 82nd for the Pro 580 and 77th for the RX 7900 GRE, reflect the broader benchmark mix, but the head-to-head data is what matters for direct comparison.
