AMD Radeon Pro 580 vs AMD Radeon RX Vega 64 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive sweep for the AMD Radeon RX Vega 64 across all three shared benchmark tests. In Geekbench Metal, the RX Vega 64 scores 68,750 against the Radeon Pro 580's 39,213, a 75.3% advantage. That is the largest single-test margin in this comparison. The OpenCL results tell a similar story: 62,552 versus 38,457, a 62.7% delta. Vulkan narrows the gap slightly but still favors the RX Vega 64 by 54.9%, with scores of 67,032 and 43,285 respectively.

The RX Vega 64 wins all three head-to-head tests, with a 3-0 record in the database. The average benchmark score reinforces this pattern: the RX Vega 64 sits at 50,001, while the Radeon Pro 580 averages 40,318. That is roughly a 24% gap in aggregate performance, though the individual test deltas are larger because the Pro 580's strongest result (Vulkan) is still far behind the Vega 64's weakest shared test result.

Context from the nearest rivals list adds nuance. The RX Vega 64's average score places it within 0.1% of the NVIDIA GeForce RTX 5070 Ti (49,957) and 0.5% of the Intel Arc A550M (49,737). It sits 1.9% behind the AMD Radeon RX 6900 XT (50,951) and 3.1% ahead of the RX 6800 XT (48,477). The Radeon Pro 580, by contrast, is essentially tied with the NVIDIA GeForce RTX 5070 (40,377, a 0.1% deficit), 0.6% ahead of the AMD Radeon Pro WX 7100 (40,063), 1.4% behind the Radeon Pro 5300 (40,870), and 1.9% ahead of the NVIDIA RTX A500 Mobile (39,568). These positions show two cards operating in different performance tiers despite both being AMD products from the same era.

Where Each One Wins

The RX Vega 64 wins every category where both cards have recorded scores. It leads in Metal, OpenCL, and Vulkan compute workloads. The data does not show a single test where the Radeon Pro 580 comes out ahead. This makes the use-case split straightforward: for any application that leverages these APIs, the RX Vega 64 is the faster card.

However, the Radeon Pro 580's role is not defined by raw performance in these synthetic tests. Its specifications point to a different intended environment. The Pro 580 is listed as an IGP (integrated graphics processor) with no power connectors and a 185 W TDP, designed for portable devices where the display outputs are "Portable Device Dependent". The RX Vega 64, in contrast, is a dual-slot add-in card requiring 2x 8-pin power connectors and a 600 W suggested power supply. These are not interchangeable products in practice.

The performance percentile ranking shows less separation than the raw scores suggest. The RX Vega 64 sits at the 86th percentile among all GPUs, while the Radeon Pro 580 sits at the 82nd. That 4-point percentile gap reflects that both cards are above average in the database, but the Vega 64 is closer to the top tier. For users whose workloads are bound by compute throughput, the RX Vega 64 is the clear choice. For systems that require an integrated solution with lower power draw, the Pro 580 is the only option that fits the form factor.

Architecture Differences

The two cards come from different generations of AMD's Graphics Core Next architecture. The RX Vega 64 uses the Vega 10 chip built on GCN 5.0, while the Radeon Pro 580 uses the Ellesmere chip on GCN 4.0. Both are fabricated by GlobalFoundries on a 14 nm process, but the transistor counts differ substantially: the Vega 10 packs 12,500 million transistors on a 495 mm² die, while Ellesmere has 5,700 million on 232 mm². The transistor density is similar (25.3M per mm² versus 24.6M per mm²), indicating the process node is comparable, but the Vega chip is more than twice the size.

The compute resources scale accordingly. The RX Vega 64 has 4,096 shading units, 256 texture mapping units, and 64 ROPs. The Radeon Pro 580 has 2,304 shading units, 144 TMUs, and 32 ROPs. That is 78% more shading units, 78% more TMUs, and twice the ROP count for the Vega 64. Clock speeds also favor the Vega 64: base clock of 1247 MHz versus 1100 MHz, and boost clock of 1546 MHz versus 1200 MHz. The combination of more units and higher clocks produces the large performance gap observed in benchmarks.

Memory architecture is another major divergence. The RX Vega 64 uses 8 GB of HBM2 on a 2048-bit bus, yielding 483.8 GB/s of bandwidth. The Radeon Pro 580 uses 8 GB of GDDR5 on a 256-bit bus, delivering 217.0 GB/s. The Vega 64's memory bandwidth is more than double. The memory clock specifications also differ: 945 MHz (1890 Mbps effective) for the Vega 64 versus 1695 MHz (6.8 Gbps effective) for the Pro 580, though the HBM2's wider bus compensates for its lower clock rate.

Feature support shows some differences as well. Both cards support OpenGL 4.6 and Vulkan 1.3, but the RX Vega 64 supports DirectX 12 (12_1) while the Radeon Pro 580 is limited to DirectX 12 (12_0). The Vega 64 also has higher theoretical throughput rates: 98.94 GPixel/s pixel rate and 395.8 GTexel/s texture rate, versus 38.40 GPixel/s and 172.8 GTexel/s for the Pro 580. Floating-point performance follows the same pattern: 12.66 TFLOPS FP32 and 25.33 TFLOPS FP16 (2:1) for the Vega 64, while the Pro 580 manages 5.530 TFLOPS for both FP32 and FP16 (1:1).

The Verdict

The data presents a clear hierarchy. The AMD Radeon RX Vega 64 outperforms the AMD Radeon Pro 580 in every recorded benchmark category, with deltas ranging from 54.9% to 75.3%. Users who need maximum compute throughput should choose the RX Vega 64 without hesitation. Its average benchmark score of 50,001 places it alongside modern mid-range and upper-mid-range GPUs, as evidenced by its proximity to the RTX 5070 Ti and RX 6900 XT in the nearest rivals list.

The Radeon Pro 580, however, serves a different purpose. Its IGP form factor, lack of power connectors, and lower 185 W TDP indicate it was designed for integrated systems where the RX Vega 64's dual-slot footprint and 295 W power draw would be impractical. The Pro 580's average score of 40,318 still places it in the 82nd percentile, and its nearest rivals include the RTX 5070 and Radeon Pro WX 7100, showing it remains competitive within its own class.

The choice between these two cards should be driven by system constraints rather than performance alone. In a desktop with adequate power delivery and physical space, the RX Vega 64 is categorically superior. In a portable or integrated platform where expansion cards are not an option, the Radeon Pro 580 is the only one of these two that can be used at all. The benchmark data cannot override physical compatibility.
