Intel Arc A310E vs NVIDIA RTX PRO 4000 Blackwell Comparison

The Verdict

The data presents a stark contrast between two professional GPUs aimed at entirely different segments. The Intel Arc A310E is an entry-level, end-of-life part with a 50th percentile ranking across all GPUs and an average benchmark score of zero in the database. The NVIDIA RTX PRO 4000 Blackwell is an active, high-end workstation card with a 72nd percentile ranking and an average benchmark score of 27,135.

The RTX PRO 4000 Blackwell dominates in every measurable category. It delivers 36.83 TFLOPS of FP32 compute versus 3.072 TFLOPS for the Arc A310E, which is a 12x advantage. Memory bandwidth tells a similar story: 672.0 GB/s versus 124.0 GB/s, a 5.4x gap. The NVIDIA card also carries 24 GB of GDDR7 memory on a 192-bit bus, while the Intel card offers 4 GB of GDDR6 on a 64-bit bus.

The Arc A310E is a low-profile, power-efficient option for basic display output or light compute workloads. It draws 75 W, requires no power connectors, and fits in a 168 mm length. The RTX PRO 4000 Blackwell draws 140 W, needs a single 16-pin connector, and spans 241 mm. The data confirms the NVIDIA card is the clear choice for any serious professional workload, while the Intel card serves only the most constrained environments.

Architecture Differences

The two GPUs come from different architectural generations and foundry processes. The Arc A310E uses Intel's Xe-HPG architecture on the DG2-128 chip, built on TSMC's 6 nm process. It belongs to the Alchemist (Arc 3) generation. The RTX PRO 4000 Blackwell uses NVIDIA's Blackwell 2.0 architecture on the GB203 chip, built on TSMC's 5 nm process, and belongs to the Blackwell PRO W (x000) generation.

Transistor counts reveal the scale difference. The Intel chip packs 7,200 million transistors on a 157 mm² die, yielding a density of 45.9M transistors per mm². The NVIDIA chip contains 45,600 million transistors on a 378 mm² die, with a density of 120.6M per mm². The NVIDIA die is 2.4x larger physically but holds 6.3x more transistors.

Compute resources diverge sharply. The Arc A310E has 768 shading units, 32 TMUs, 16 ROPs, and 6 ray tracing cores. The RTX PRO 4000 Blackwell has 8,960 shading units, 280 TMUs, 96 ROPs, 70 ray tracing cores, and 280 tensor cores. The NVIDIA card also uses a different FP16 path: it runs FP16 at the same rate as FP32 (36.83 TFLOPS, 1:1), while the Intel card achieves 6.144 TFLOPS FP16 through a 2:1 ratio.

Memory architecture differs fundamentally. The Intel card uses 4 GB of GDDR6 with a 64-bit bus. The NVIDIA card uses 24 GB of GDDR7 with a 192-bit bus. This combination gives the RTX PRO 4000 Blackwell 5.4x the bandwidth. The Intel card's memory clock is 1937 MHz (15.5 Gbps effective), while the NVIDIA card runs at 1750 MHz (28 Gbps effective), meaning the higher bandwidth comes from the wider bus and faster effective data rate.

Interface standards also differ. The Arc A310E uses PCIe 4.0 x8, while the RTX PRO 4000 Blackwell uses PCIe 5.0 x16. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs are similar in count but different in version: the Intel card has 4x mini-DisplayPort 2.0, and the NVIDIA card has 4x DisplayPort 2.1b.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between these two cards. The Arc A310E has no recorded benchmark scores, and its average benchmark score is zero. The RTX PRO 4000 Blackwell, however, has a full suite of benchmark results that place it solidly in the upper tier of GPUs.

The RTX PRO 4000 Blackwell scores 4,648 in 3DMark Steel Nomad DX12. In Geekbench Vulkan, it reaches 194,168. PassMark results show 28427 in G3D, 14805 in GPU Compute, 1265 in G2D, and legacy DirectX scores of 354 in DX9, 276 in DX11, 173 in DX10, and 97 in DX12. These figures establish a baseline for what the NVIDIA card delivers.

Since the Intel card has no recorded scores, the comparison must rely on architectural specifications. The RTX PRO 4000 Blackwell delivers 36.83 TFLOPS FP32, which is 12x the Arc A310E's 3.072 TFLOPS. Pixel throughput favors NVIDIA at 197.3 GPixel/s versus 32.00 GPixel/s, a 6.2x margin. Texture throughput shows 575.4 GTexel/s versus 64.00 GTexel/s, a 9x margin.

The nearest rivals for the RTX PRO 4000 Blackwell show how it stacks against other established GPUs. The AMD Radeon RX 6700 XT scores 27,425, which is 1.1% higher than the NVIDIA card's 27,135 average. The NVIDIA GeForce RTX 4070 Mobile also scores 27,435, again 1.1% higher. The desktop RTX 3090 scores 27,565, 1.6% higher. The older RTX A4000 scores 26,683, which is 1.7% lower. This places the RTX PRO 4000 Blackwell in a tight competitive band around the 27,000 to 27,500 mark, slightly behind a desktop RTX 3090 but ahead of the RTX A4000.
