Intel Arc A310E vs NVIDIA RTX PRO 4500 Blackwell Workstation Comparison

Where Each One Wins

The Intel Arc A310E and NVIDIA RTX PRO 4500 Blackwell Workstation occupy entirely different segments of the GPU spectrum, and the recorded data reflects this clearly. The Arc A310E is positioned as a low-power, compact solution with a 75 W TDP, a single-slot profile, and no power connectors. It draws its operating power entirely from the PCIe slot, which makes it suitable for systems with modest power delivery. The RTX PRO 4500, in contrast, is a dual-slot workstation card with a 200 W TDP, a single 16-pin power connector, and a suggested PSU of 550 W. These are not competing products in the conventional sense; they serve different workloads and different chassis constraints.

The Arc A310E wins on physical simplicity. Its dimensions are 168 mm in length, 69 mm in height, and 20 mm in width, compared to the RTX PRO 4500's 267 mm length, 111 mm height, and 40 mm width. The Intel card fits into compact or embedded systems where space is at a premium. It also uses a PCIe 4.0 x8 interface, while the NVIDIA card uses PCIe 5.0 x16, which indicates a much wider data path for the workstation part. The Arc A310E is marked as end-of-life, with its successor being Battlemage, whereas the RTX PRO 4500 is active production and follows Workstation Ada in NVIDIA's lineup.

The RTX PRO 4500 wins on raw compute capacity in every measurable category. Its FP32 throughput is 50.53 TFLOPS against the Arc A310E's 3.072 TFLOPS. Its texture rate is 789.5 GTexel/s versus 64.00 GTexel/s. Its pixel rate is 269.6 GPixel/s versus 32.00 GPixel/s. The NVIDIA card has 82 RT cores and 328 tensor cores, while the Intel card has 6 RT cores and no tensor core field in the data. Memory capacity differs massively: 32 GB of GDDR7 on a 256-bit bus versus 4 GB of GDDR6 on a 64-bit bus. Bandwidth is 896.0 GB/s versus 124.0 GB/s.

The use-case split is therefore straightforward. The Arc A310E is for low-power, space-constrained deployments where basic graphics output and modest 3D acceleration are sufficient. The RTX PRO 4500 is for professional workloads that demand large memory pools, high bandwidth, and substantial compute throughput. Each product wins in the domain it was designed for.

Architecture Differences

The two GPUs come from different architectural generations and foundries. The Intel Arc A310E uses the DG2-128 chip, built on the Xe-HPG architecture, and belongs to the Alchemist (Arc 3) generation. It is fabricated on a 6 nm process at TSMC, with 7,200 million transistors on a 157 mm² die. The transistor density is 45.9 million per mm². The NVIDIA RTX PRO 4500 uses the GB203 chip, built on the Blackwell 2.0 architecture, and belongs to the Blackwell PRO W (x000) generation. It is fabricated on a 5 nm process at TSMC, with 45,600 million transistors on a 378 mm² die. The transistor density is 120.6 million per mm².

The transistor count difference is substantial: the NVIDIA chip has over six times the transistor count of the Intel chip. The die size is more than double, and the density is roughly 2.6 times higher. These figures indicate a much more complex chip with many more functional units. The Intel card has 768 shading units, 32 TMUs, and 16 ROPs. The NVIDIA card has 10,496 shading units, 328 TMUs, and 112 ROPs. The ratio of shading units is approximately 13.7 to 1.

Clock behavior also differs. The Arc A310E has a base clock of 2000 MHz and a boost clock of 2000 MHz, meaning it runs at a fixed frequency. The RTX PRO 4500 has a base clock of 1635 MHz and a boost clock of 2407 MHz, so it scales upward under load by a significant margin. Memory clocks differ as well: the Intel card runs at 1937 MHz with 15.5 Gbps effective, while the NVIDIA card runs at 1750 MHz with 28 Gbps effective. The NVIDIA memory is faster per pin despite a lower raw clock because GDDR7 transfers more data per cycle.

FP16 performance reveals an architectural difference. The Arc A310E delivers 6.144 TFLOPS FP16 at a 2:1 ratio relative to FP32, meaning it uses a packed math path. The RTX PRO 4500 delivers 50.53 TFLOPS FP16 at a 1:1 ratio, meaning it has full-rate FP16 throughput equal to its FP32 rate. This matters for workloads that mix precision levels.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries for this pair, and the win counters are both zero. The nearest-rival lists for both cards are empty. This means the comparative analysis must rely on the specification-level data recorded for each product.

The largest single-category gap in raw throughput is in FP32 compute. The RTX PRO 4500 delivers 50.53 TFLOPS, which is approximately 16.4 times the Arc A310E's 3.072 TFLOPS. In texture rate, the NVIDIA card's 789.5 GTexel/s is roughly 12.3 times the Intel card's 64.00 GTexel/s. Pixel rate shows a smaller but still large gap: 269.6 GPixel/s versus 32.00 GPixel/s, a factor of about 8.4.

Memory bandwidth is another decisive category. The RTX PRO 4500's 896.0 GB/s is approximately 7.2 times the Arc A310E's 124.0 GB/s. The memory bus width is four times wider (256 bit versus 64 bit), and the memory type is newer (GDDR7 versus GDDR6). Memory capacity is eight times larger (32 GB versus 4 GB).

The Arc A310E does hold advantages in certain efficiency metrics. Its TDP of 75 W is 125 W lower than the RTX PRO 4500's 200 W. Its FP32 throughput per watt is 40.96 GFLOPS/W (3.072 TFLOPS divided by 75 W), while the NVIDIA card delivers 252.65 GFLOPS/W (50.53 TFLOPS divided by 200 W). The NVIDIA card is actually more efficient per watt despite its higher total power draw, because its compute advantage outpaces its power advantage. However, the Intel card requires no external power connector and has a suggested PSU of 250 W, versus 550 W for the NVIDIA card. The system-level power footprint is much lower for the Intel part.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ: the Arc A310E has four mini-DisplayPort 2.0 connectors, while the RTX PRO 4500 has four DisplayPort 2.1b connectors. Both support four displays, but the connector form factor and DisplayPort version differ.
