Architecture Differences

The Intel Arc A580 is built on the Xe-HPG architecture, specifically the DG2-512 chip, part of the Alchemist generation. It uses a 6 nm process at TSMC, packing 21,700 million transistors into a 406 mm² die, yielding a transistor density of 53.4M per mm². The AMD Radeon RX 6750 GRE 12 GB uses RDNA 2.0 with the Navi 22 chip, part of the Navi II generation. It is fabricated on a 7 nm process at TSMC, with 17,200 million transistors on a 335 mm² die, resulting in a density of 51.3M per mm². Intel's newer node gives it a transistor count advantage, but AMD compensates with higher clocks.

The compute layouts diverge sharply. The Arc A580 has 3072 shading units, 192 TMUs, and 96 ROPs, with 24 dedicated ray tracing cores. The RX 6750 GRE 12 GB has fewer execution resources: 2560 shading units, 160 TMUs, and 64 ROPs, but it packs 40 ray tracing cores. Intel's wider allocation of texture and pixel units suggests a different workload balance, while AMD's higher RT core count points to a stronger ray tracing focus per shader.

Clock behavior is a major architectural differentiator. AMD runs at a 2321 MHz base and 2581 MHz boost, with a 2439 MHz game clock, while Intel sits at 1700 MHz base and 2000 MHz boost. The result is that AMD achieves higher peak throughput despite fewer cores. FP32 performance is 13.21 TFLOPS for AMD versus 12.29 TFLOPS for Intel, and FP16 is 26.43 TFLOPS versus 24.58 TFLOPS, with both using a 2:1 ratio.

Memory subsystems also differ. Intel uses a 256-bit bus with 8 GB and 512.0 GB/s bandwidth, while AMD uses a 192-bit bus with 12 GB and 432.0 GB/s. AMD's memory runs at 2250 MHz (18 Gbps effective) versus Intel's 2000 MHz (16 Gbps effective), but the wider Intel bus still delivers more raw bandwidth. The 12 GB frame buffer on AMD is a clear advantage for modern games with high VRAM usage.

Where Each One Wins

The AMD Radeon RX 6750 GRE 12 GB wins every direct benchmark comparison. In 3DMark Steel Nomad DX12, it leads by 7.2%, showing a solid advantage in a modern DirectX 12 workload. The Geekbench Vulkan gap is far larger at 27.2%, indicating that AMD's architecture scales much better in that specific compute-and-graphics test. For users prioritizing raw performance in these measured scenarios, AMD is the clear choice.

The Intel Arc A580 wins on aggregate average score, posting 57756 versus 55698 for AMD. This is notable because Intel achieves this with a lower TDP of 175 W versus 250 W, meaning it delivers competitive overall performance per watt in the broader benchmark suite. The Arc A580 also has higher memory bandwidth at 512.0 GB/s, which can benefit certain bandwidth-sensitive workloads even if it does not translate to wins in the shared tests.

Use-case splits are evident. AMD's 12 GB VRAM and higher clock speeds make it better suited for high-resolution gaming and titles that demand large frame buffers. Intel's higher bandwidth and lower power draw could appeal to users with tighter power budgets or workloads that favor memory throughput. The Arc A580 also offers DisplayPort 2.0 outputs, which is a forward-looking feature for high refresh rate displays, whereas AMD sticks with DisplayPort 1.4a.

Head-to-Head Benchmarks

The first shared test is 3DMark Steel Nomad DX12, a demanding DirectX 12 workload. The AMD Radeon RX 6750 GRE 12 GB scores 2402, beating the Intel Arc A580's 2229 by 7.2%. This margin is meaningful but not overwhelming, suggesting that Intel's architecture is competitive in traditional rasterization but falls short in this specific DX12 path. The AMD card's higher boost clock of 2581 MHz likely drives this result, allowing it to outpace Intel's 2000 MHz boost despite having fewer shading units.

The second test, Geekbench Vulkan, reveals a much larger gap. AMD scores 108994 versus 79381 for Intel, a 27.2% difference. This is a substantial win for AMD, indicating that its RDNA 2.0 architecture handles Vulkan compute and graphics far more efficiently. The Arc A580's 24 RT cores and 3072 shading units do not translate into Vulkan performance, whereas AMD's 40 RT cores and more efficient scheduler appear to be decisive. This benchmark alone accounts for the majority of the performance difference between the two cards.

In the broader context, the Intel Arc A580 holds an advantage in average benchmark score, 57756 versus 55698, which is roughly a 3.7% lead. This is an interesting inversion: AMD wins both direct comparisons, yet Intel wins the aggregate metric. The explanation lies in the other benchmarks that contribute to the average, where the Arc A580's higher bandwidth and wider memory bus may provide benefits. The Arc A580 also has a higher pixel rate of 192.0 GPixel/s versus 165.2 GPixel/s, and a higher transistor count, which could help in certain compute tasks.

The wins are lopsided at 2-0 in favor of AMD, but the average score data shows that Intel is not without merit. The Arc A580's nearest rivals include the AMD Radeon RX 5600 OEM (0.6% lower average score) and the AMD Radeon RX 6950 XT (1.1% lower), placing it in strong company. The RX 6750 GRE 12 GB's nearest rivals include the NVIDIA GeForce RTX 5080 (0.7% lower) and the AMD Radeon 8060S (0.1% lower), showing it sits at a similar competitive level. Both cards are firmly in the upper tier of GPU performance, with the AMD card having the edge in the tests that matter most for gaming.
