Intel Arc A580 vs NVIDIA RTX A6000 Comparison

Head-to-Head Benchmarks

The recorded data offers only two direct comparison points between the Intel Arc A580 and the NVIDIA RTX A6000, and both fall decisively in favor of the workstation-class NVIDIA card. In the Geekbench OpenCL test, the RTX A6000 scores 193,937 against the Arc A580's 91,657, a delta of 52.7% in NVIDIA's favor. The Vulkan result tells a similar story: 164,462 for the RTX A6000 versus 79,381 for the Arc A580, a 51.7% gap. These are not marginal differences; the NVIDIA card roughly doubles the Intel card's compute throughput in both API environments.

The magnitude of these deltas is striking when placed against the broader benchmark landscape. The Arc A580's average benchmark score across all recorded tests is 57,756, which places it at the 87th percentile of all GPUs in the database. The RTX A6000, despite its much higher raw scores in these two tests, has an average of 44,075 and sits at the 84th percentile. This apparent contradiction is explained by the test mix: the RTX A6000's average is dragged down by its Passmark legacy DirectX scores, which are low (155 in DirectX 10, 191 in DirectX 11, 87 in DirectX 12, 245 in DirectX 9), while the Arc A580's benchmark suite contains only the two Geekbench entries and one 3DMark Steel Nomad result. The 3DMark score of 2,229 for the Arc A580 is not matched by a corresponding RTX A6000 entry, so direct cross-referencing is limited.

What the head-to-head numbers imply is that for general compute workloads, the RTX A6000's advantage is overwhelming. The OpenCL delta of 52.7% and the Vulkan delta of 51.7% are consistent with each other, suggesting a uniform compute advantage rather than an API-specific quirk. The Arc A580's nearest rivals in the database include the AMD Radeon RX 5600 OEM (0.6% behind), the Intel Arc A570M (0.8% behind), the AMD Radeon RX 9070 GRE (0.7% ahead), and the AMD Radeon RX 6950 XT (1.1% behind). This clustering within roughly 1% of the Arc A580's average score indicates that the Intel card is competitively positioned among mid-range GPUs, but the RTX A6000 occupies a different performance tier entirely, as its nearest rivals, the RTX 4090 Mobile (0.9% ahead) and the RTX 4070 Ti (1.6% behind), are all high-end parts.

The Verdict

The data supports a straightforward conclusion: the NVIDIA RTX A6000 is the superior performer in every direct head-to-head measurement, and the differences are large enough to be class-defining. The RTX A6000 leads by more than half in both OpenCL and Vulkan compute tests. For anyone whose workload is compute-bound, the choice is unambiguous. The RTX A6000 also offers 48 GB of memory, a 384-bit bus, and 768.0 GB/s of bandwidth, compared to the Arc A580's 8 GB, 256-bit bus, and 512.0 GB/s. These are not subtle differences; they represent different categories of hardware.

However, the Arc A580 has its own claims. Its average benchmark score of 57,756 is actually 31% higher than the RTX A6000's 44,075, though this is an artifact of the test sets rather than a true performance victory. The Arc A580's 87th percentile versus the RTX A6000's 84th percentile similarly flatters the Intel card because the RTX A6000's Passmark results are included in its average while the Arc A580's are not. The honest reading of the data is that the RTX A6000 wins the tests that matter for compute-heavy professional use, while the Arc A580's standing in the database is inflated by the absence of legacy DirectX tests from its benchmark suite.

The RTX A6000 is an end-of-life product, released in 2020 with a launch MSRP of 4,649 USD, while the Arc A580 is active and was released in 2023. The production status difference does not change the measured performance, but it does affect availability and long-term support considerations. The data indicates that the RTX A6000 remains a compute powerhouse even as it exits production, and the Arc A580, while newer, does not approach it in raw throughput.

Where Each One Wins

The RTX A6000 wins in all direct comparisons. In Geekbench OpenCL, it scores 193,937 versus 91,657, a 52.7% advantage. In Geekbench Vulkan, it scores 164,462 versus 79,381, a 51.7% advantage. These are the only head-to-head benchmarks available, and they favor NVIDIA in both cases. The RTX A6000 also wins on memory capacity, bandwidth, shading units, texture units, ray tracing cores, and tensor cores. It has 10,752 shading units against 3,072, 336 TMUs against 192, 112 ROPs against 96, 84 RT cores against 24, and 336 tensor cores against none listed for the Arc A580.

The Arc A580's wins are less visible in the recorded data but are still present. Its 3DMark Steel Nomad DX12 score of 2,229 is a modern API test that the RTX A6000 does not have a recorded result for, so it cannot be directly compared. The Arc A580 also posts a higher average benchmark score, 57,756 versus 44,075, and a higher percentile ranking, 87 versus 84. Its transistor density of 53.4 million per square millimeter on a 6 nm process is higher than the RTX A6000's 45.1 million per square millimeter on an 8 nm process, indicating a more modern manufacturing approach. The Arc A580's texture rate of 384.0 GTexel/s and pixel rate of 192.0 GPixel/s are lower than the RTX A6000's 604.8 GTexel/s and 201.6 GPixel/s respectively, so the Intel card loses those specific metrics as well.

The use-case split is therefore: the RTX A6000 for compute-intensive professional workloads, large model fitting, scientific simulation, and any task that benefits from massive memory capacity, and the Arc A580 for modern API feature support, including DisplayPort 2.0 outputs that the RTX A6000 lacks (the RTX A6000 has four DisplayPort 1.4a outputs instead of Intel's 1x HDMI 2.1 and 3x DisplayPort 2.0).

Architecture Differences

The two GPUs come from different architectural lineages. The Intel Arc A580 uses the DG2-512 chip built on the Xe-HPG architecture, specifically the Alchemist generation, and is fabricated on a 6 nm process at TSMC. The NVIDIA RTX A6000 uses the GA102 chip built on the Ampere architecture, belonging to the Workstation Ampere generation, fabricated on an 8 nm process at Samsung. The process node difference matters for transistor density: the Intel chip packs 21,700 million transistors into a 406 square millimeter die at 53.4 million per square millimeter, while the NVIDIA chip has 28,300 million transistors on a 628 square millimeter die at 45.1 million per square millimeter.

The compute architecture differs in its fp16 handling. The Arc A580 lists 24.58 TFLOPS for fp16 at a 2:1 ratio relative to its 12.29 TFLOPS fp32, while the RTX A6000 lists 38.71 TFLOPS for both fp16 and fp32 at a 1:1 ratio. The RTX A6000 also has dedicated tensor cores, 336 of them, which the Arc A580 does not list at all. The RT cores also differ, 84 on the NVIDIA card against 24 on the Arc A580.

The memory architecture also diverges beyond capacity alone. The RTX A6000's 48 GB capacity is paired with a bandwidth of 768.0 GB/s over a 384-bit bus, while the Arc A580's 8 GB capacity sits on a 256-bit bus with 512.0 GB/s bandwidth. Both use GDDR6 memory clocked at 2000 MHz with 16 Gbps effective. The display output capabilities differ as well, with the Arc A580 offering 1x HDMI 2.1 and 3x DisplayPort 2.0, whereas the RTX A6000 has 4x DisplayPort 1.4a and no HDMI output listed.

Specification Differences

The two cards differ in nearly every measurable specification, with only a few shared fields. Both are dual-slot designs with a PCIe 4.0 x16 bus interface and support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The base and boost clocks differ: the Arc A580 runs at 1700 MHz base and 2000 MHz boost, while the RTX A6000 operates at 1410 MHz base and 1800 MHz boost. Memory speed is identical at 2000 MHz with 16 Gbps effective.

The memory configuration is a major split: 8 GB versus 48 GB, 256-bit versus 384-bit, 512.0 GB/s versus 768.0 GB/s. The compute units follow suit: 3,072 shading units against 10,752, 192 TMUs against 336, 96 ROPs against 112, 24 RT cores against 84, and the RTX A6000's 336 tensor cores against none listed for the Arc A580. The pixel rate is 192.0 GPixel/s for Intel versus 201.6 GPixel/s for NVIDIA, and the texture rate is 384.0 GTexel/s versus 604.8 GTexel/s. The fp32 compute is 12.29 TFLOPS against 38.71 TFLOPS.

Power delivery differs as well: the Arc A580 uses 2x 8-pin connectors with a 175 W TDP and a 450 W suggested PSU, while the RTX A6000 uses a single 8-pin EPS connector with a 300 W TDP and a 700 W suggested PSU. The RTX A6000 is physically specified at 267 mm in length and 112 mm in height, with the Arc A580 lacking listed dimensions. The process, foundry, transistor count, and die area all differ, as do the production statuses and release dates. The RTX A6000 has a recorded launch MSRP of 4,649 USD, while the Arc A580 has no launch MSRP field in the database.
