Architecture Differences

The two GPUs represent fundamentally different design philosophies. Intel's Arc A310E is built on Xe-HPG, a graphics-first architecture optimized for efficiency at low power. The NVIDIA RTX PRO 5000 uses Blackwell 2.0, a compute-oriented architecture with dedicated tensor cores and ray tracing hardware.

The transistor counts reveal the scale gap. Intel packs 7,200 million transistors into a 157 mm² die, achieving a density of 45.9M per mm². NVIDIA packs 92,200 million transistors into a 750 mm² die, reaching 122.9M per mm². The NVIDIA chip is more than 12 times larger in transistor count and nearly 5 times larger in die area.

Shader resources differ massively. The Arc A310E has 768 shading units, 32 TMUs, and 16 ROPs. The RTX PRO 5000 has 14,080 shading units, 440 TMUs, and 160 ROPs. That is roughly 18 times more shading units, 13.75 times more TMUs, and 10 times more ROPs. The NVIDIA card also includes 110 ray tracing cores and 440 tensor cores, while Intel provides 6 ray tracing cores and no tensor core count listed.

Memory architecture reflects the intended workloads. The Arc A310E uses 4 GB GDDR6 with a 64-bit bus. The RTX PRO 5000 uses 72 GB GDDR7 with a 384-bit bus. Memory bandwidth jumps from 124.0 GB/s to 1.34 TB/s, a factor of approximately 10.8. The memory clock differs as well: Intel runs at 1937 MHz (15.5 Gbps effective), NVIDIA at 1750 MHz (28 Gbps effective).

Process technology and manufacturing both use TSMC, but at different nodes. Intel uses 6 nm, NVIDIA uses 5 nm. The newer node contributes to NVIDIA's higher transistor density despite the much larger die.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ: Intel provides 4x mini-DisplayPort 2.0, NVIDIA provides 4x DisplayPort 2.1b. The bus interface also differs, with Intel on PCIe 4.0 x8 and NVIDIA on PCIe 5.0 x16.

Production status separates them further. The Arc A310E is end-of-life, released in March 2024, with Battlemage as its successor. The RTX PRO 5000 is active, released in October 2025, succeeding Workstation Ada.

The Verdict

The data supports a clear separation of roles. The Intel Arc A310E is a low-power, compact solution with a 75 W TDP, no external power connectors, and a single-slot footprint. It fits in constrained environments where a 250 W suggested PSU is sufficient and where space is limited to 168 mm length, 69 mm height, and 20 mm width.

The NVIDIA RTX PRO 5000 is a high-throughput workstation card. Its 66.94 TFLOPS FP32, 1.34 TB/s memory bandwidth, and 72 GB capacity target compute-heavy workloads. The 300 W TDP, 700 W suggested PSU, and dual-slot dimensions indicate a machine designed around this GPU, not a card adapted to existing systems.

For users requiring maximum compute throughput, large memory pools, and tensor core acceleration, the RTX PRO 5000 is the only choice. For users prioritizing low power draw, minimal physical footprint, and simple installation without power cabling, the Arc A310E fits. The recorded benchmark data only covers the RTX PRO 5000, with an average score of 6407 and a percentile rank of 37 among all GPUs. Its nearest rivals in the database are the NVIDIA GeForce GTX 460 SE and GTX 580M, both with an average score of 6389 and a delta of 0.3%, and the AMD Radeon Vega 10 Mobile and NVIDIA Quadro M5000M, with scores of 6476 and 6481 respectively, showing deltas of -1.1%.

Head-to-Head Benchmarks

The database contains benchmark results only for the NVIDIA RTX PRO 5000. The Intel Arc A310E has no recorded benchmark entries, so direct numerical comparisons are unavailable. The head-to-head benchmark table is empty, and neither card records a win count.

The RTX PRO 5000's PassMark G3D score of 24310 places it in a specific performance tier. Its average benchmark score across all recorded tests is 6407, with a percentile rank of 37 among all GPUs. This percentile indicates that 63% of GPUs in the database score higher on average, which reflects the mixed nature of the recorded tests, some of which are legacy DirectX versions.

The DirectX 9 score of 311, DirectX 10 score of 175, and DirectX 11 score of 219 show varying performance across API generations. The DirectX 12 score of 78 is notably lower, suggesting that the 3DMark Steel Nomad DX12 test at 9579.5 measures a different workload profile. The PassMark GPU compute score of 15667 confirms strong computational throughput, consistent with the 66.94 TFLOPS FP32 specification.

The nearest rival comparisons for the RTX PRO 5000 use average scores. The NVIDIA GeForce GTX 460 SE and GTX 580M each score 6389, a delta of 0.3% relative to the RTX PRO 5000's 6407 average. The AMD Radeon Vega 10 Mobile scores 6476, a delta of -1.1%, and the NVIDIA Quadro M5000M scores 6481, also a delta of -1.1%. These deltas indicate the RTX PRO 5000's average score sits within 1.1% of these four rivals, despite the vast specification differences.

Where Each One Wins

The Intel Arc A310E wins in physical integration scenarios. Its 75 W TDP requires no external power connector, and the 250 W suggested PSU fits standard office or embedded systems. The single-slot design at 168 mm length, 69 mm height, and 20 mm width allows installation in compact chassis where the RTX PRO 5000's 267 mm length, 111 mm height, and 40 mm width would not fit. The PCIe 4.0 x8 interface is sufficient for its 124.0 GB/s memory bandwidth.

The NVIDIA RTX PRO 5000 wins in every compute and memory metric recorded. Its FP32 throughput of 66.94 TFLOPS is approximately 21.8 times higher than the Arc A310E's 3.072 TFLOPS. The FP16 performance gap is larger still, since NVIDIA sustains 66.94 TFLOPS at 1:1 ratio while Intel's 6.144 TFLOPS is at 2:1, meaning the NVIDIA card delivers roughly 10.9 times the FP16 throughput. The pixel rate of 380.3 GPixel/s versus 32.00 GPixel/s and texture rate of 1,045.9 GTexel/s versus 64.00 GTexel/s show similar multiples.

Memory capacity favors NVIDIA decisively: 72 GB versus 4 GB, an 18 times difference. Bandwidth of 1.34 TB/s versus 124.0 GB/s gives NVIDIA approximately 10.8 times the data throughput. The 384-bit GDDR7 memory bus with 28 Gbps effective speed supports workloads that require large datasets or high-resolution textures.

The RTX PRO 5000's tensor cores and 110 ray tracing cores provide hardware acceleration absent from the Arc A310E's simpler configuration. The 440 tensor cores support AI workloads, while the ray tracing cores handle ray-traced rendering. The Arc A310E's 6 ray tracing cores offer limited ray tracing capability at a smaller scale.

The production status also favors NVIDIA. The RTX PRO 5000 is active with a successor not yet listed, while the Arc A310E is end-of-life with Battlemage already designated as its successor. Users seeking long-term driver support and availability should favor the active product.

The benchmark data, while only covering NVIDIA, shows the RTX PRO 5000's average score of 6407 sits close to its nearest rivals. The percentile rank of 37 indicates that its average score across all tests is lower than most GPUs, but the individual PassMark G3D score of 24310 and compute score of 15667 demonstrate strength in modern workloads. The Arc A310E has no recorded benchmarks, leaving its real-world performance unquantified in the database.
