Architecture Differences

The two GPUs come from different architectural lineages. The NVIDIA GeForce RTX 3080 uses the Ampere architecture on the GA102 chip, fabricated by Samsung on an 8 nm process. The Intel Arc A750 uses the Xe-HPG architecture with the DG2-512 chip, built by TSMC on a 6 nm process. The node difference is significant: Intel's 6 nm process allows for a transistor density of 53.4M per mm², versus 45.1M per mm² for NVIDIA's 8 nm process. However, the RTX 3080 packs more total transistors at 28,300 million, compared to Intel's 21,700 million, on a larger die of 628 mm² versus 406 mm².

The shader configuration differs substantially. The RTX 3080 has 8,704 shading units, 272 TMUs, and 96 ROPs. The Arc A750 has 3,584 shading units, 224 TMUs, and 112 ROPs. NVIDIA also includes 68 RT cores and 272 tensor cores, while Intel lists 28 RT cores and no tensor cores in the database. This gives the RTX 3080 a raw FP32 throughput of 29.77 TFLOPS, while the Arc A750 delivers 17.20 TFLOPS. The FP16 picture flips: Intel's card outputs 34.41 TFLOPS at a 2:1 ratio, while NVIDIA's is 29.77 TFLOPS at 1:1, meaning Intel has a dedicated advantage in half-precision compute.

Memory architecture is another divider. The RTX 3080 uses 10 GB of GDDR6X on a 320-bit bus for 760.3 GB/s bandwidth. The Arc A750 uses 8 GB of GDDR6 on a 256-bit bus for 512.0 GB/s. Clock speeds favor Intel: the Arc A750 boosts to 2400 MHz versus 1710 MHz for the RTX 3080. That higher clock helps Intel achieve a pixel rate of 268.8 GPixel/s and a texture rate of 537.6 GTexel/s, both above NVIDIA's 164.2 GPixel/s and 465.1 GTexel/s respectively.

Both cards support PCIe 4.0 x16 and dual-slot designs. Display outputs are similar in count: both feature 1x HDMI 2.1 and 3x DisplayPort, but Intel uses DisplayPort 2.0 while NVIDIA uses DisplayPort 1.4a. Power requirements differ, with the RTX 3080 rated at 320 W TDP and a suggested 700 W PSU, while the Arc A750 draws 225 W and recommends a 550 W PSU. The RTX 3080 uses a single 12-pin connector; Intel uses a 6-pin plus an 8-pin.

The Verdict

The data points to a clear performance hierarchy. The RTX 3080 wins 9 of the 10 head-to-head benchmark comparisons, with its only loss coming in the Vulkan test. The average benchmark score of 23,172 versus 20,582 places the NVIDIA card roughly 12.6% ahead in aggregate. In the database's percentile ranking, the RTX 3080 sits at 68th percentile of all GPUs, while the Arc A750 sits at 66th, a relatively close overall standing that reflects the Arc's strong showing in specific workloads.

For users prioritizing raw DirectX performance, the RTX 3080 is the choice. Its Passmark DirectX 11 score of 207 is 187.5% higher than the Arc A750's 72, and its DirectX 10 result of 170 is 161.5% above Intel's 65. The 3DMark Steel Nomad DX12 test shows a 68.7% lead for NVIDIA. The RTX 3080 also dominates compute workloads, with a Passmark GPU compute score of 14,397 versus 5,368, a 168.2% advantage.

The Intel Arc A750 has one clear niche: Vulkan. Its Geekbench Vulkan score of 85,631 is 60.7% higher than the RTX 3080's 33,620. This suggests that in Vulkan-based titles, the Arc A750 can outperform the more expensive NVIDIA card. Additionally, Intel's higher FP16 throughput at 34.41 TFLOPS versus 29.77 TFLOPS could benefit workloads that use half-precision math.

For most buyers, the RTX 3080 is the superior GPU. Its wins are broad and decisive across DirectX 9, 10, 11, and 12, along with OpenCL and compute. The Arc A750 is a more power-efficient option with a lower 225 W TDP and a smaller die, but its performance ceiling is lower in the majority of recorded tests. The choice narrows to whether Vulkan performance or half-precision throughput matters more than the overall DirectX and compute dominance of the RTX 3080.

Head-to-Head Benchmarks

The 3DMark Steel Nomad DX12 test opens the comparison with a decisive NVIDIA win. The RTX 3080 scores 4,407 against the Arc A750's 2,612, a 68.7% delta. This is the largest gap in the 3DMark suite and reflects NVIDIA's higher FP32 throughput and memory bandwidth advantage in modern DirectX 12 workloads.

Geekbench OpenCL shows a similar story. The RTX 3080 posts 152,423 points versus 98,554 for Intel, a 54.7% lead. The OpenCL test tends to favor raw compute resources, and NVIDIA's 8,704 shading units and 272 tensor cores provide a substantial edge over Intel's 3,584 shading units.

The Vulkan test is the outlier. The Intel Arc A750 scores 85,631, which is 60.7% higher than the RTX 3080's 33,620. This is the only benchmark where Intel wins, and the margin is substantial. The result suggests Intel's Xe-HPG architecture has a particular strength in Vulkan API execution, likely due to its driver and hardware scheduling design.

Passmark DirectX 10 and DirectX 11 tests show the largest relative deltas in the entire comparison. In DirectX 10, NVIDIA scores 170 versus Intel's 65, a 161.5% difference. DirectX 11 is even more lopsided: 207 versus 72, or 187.5% in favor of the RTX 3080. These legacy API tests highlight a generational gap in driver maturity and architectural efficiency for older workloads.

DirectX 12 narrows the gap. The RTX 3080 scores 100, and the Arc A750 scores 70, a 42.9% lead. This is closer than the older DirectX versions, but NVIDIA still holds a clear advantage. DirectX 9 shows a similar pattern: 258 versus 181, a 42.5% margin.

The Passmark G2D test, which measures 2D graphics performance, gives NVIDIA a 44% win with 1,054 points to Intel's 732. This is a less commonly discussed metric but still shows NVIDIA's dominance outside of 3D rendering.

Passmark G3D, a general 3D graphics score, doubles Intel's output. The RTX 3080 records 25,086 points, while the Arc A750 manages 12,534, a 100.1% delta. This is the closest to a 2x performance gap in the dataset.

Compute workloads show the biggest absolute disparity. The RTX 3080 scores 14,397 in Passmark GPU compute, versus 5,368 for Intel, a 168.2% advantage. This aligns with the OpenCL results and confirms that NVIDIA's compute architecture is significantly stronger in general-purpose tasks.

The aggregate picture: the RTX 3080 wins 9 of 10 benchmarks, with an average score advantage of 12.6%. The Arc A750's single Vulkan victory is notable but insufficient to offset losses elsewhere. The RTX 3080's strengths are most pronounced in legacy DirectX and compute workloads, while Intel's card shows its best relative performance in Vulkan and half-precision FP16 operations.
