AMD FirePro D300 vs Intel Arc A750 Comparison

The Intel Arc A750 and AMD FirePro D300 occupy opposite ends of the GPU timeline and performance spectrum. The Arc A750 is a modern Alchemist-generation part built for high-throughput gaming and compute, while the FirePro D300 is a legacy GCN 1.0 workstation card from 2014. Benchmark data shows a decisive advantage for Intel in every shared test, but the FirePro’s remaining strengths lie in its niche professional feature set and power profile. The data indicates a generational chasm: the Arc A750 posts an average benchmark score of 20,582, placing it in the 66th percentile of all GPUs, while the FirePro D300 averages 19,637, sitting just two percentile points lower at 64. This narrow percentile gap belies the massive individual test deltas, where the Intel card routinely triples or quadruples the AMD card’s output.

Where Each One Wins

The Intel Arc A750 wins in every benchmark category where both cards have recorded scores. In the two head-to-head tests, the Arc A750 dominates completely: it takes the Geekbench OpenCL test with a score of 98,554 versus the FirePro’s 19,515, and the Geekbench Vulkan test with 85,631 versus 19,759. That is a 405% advantage in OpenCL and a 333.4% advantage in Vulkan. These are not marginal wins; they represent entirely different performance tiers. The Arc A750 also has a much broader benchmark footprint, with scores in 3DMark Steel Nomad DX12 (2,612), Passmark DirectX 10 (65), DirectX 11 (72), DirectX 12 (70), DirectX 9 (181), G2D (732), G3D (12,534), and GPU Compute (5,368). The FirePro D300 has no recorded scores in any of those tests, so its competitive window is limited to the two Geekbench entries.

Where the FirePro D300 might “win” is in a narrow, qualitative sense: it is a single-slot card with a 150 W TDP and no auxiliary power connectors required, compared to the Arc A750’s dual-slot design, 225 W TDP, and 1x 6-pin plus 1x 8-pin power connectors. For a workstation with limited physical space or power budget, the FirePro’s form factor is an advantage. It also offers four DisplayPort 1.2 outputs, which is one more display output than the Arc A750’s combination of one HDMI 2.1 and three DisplayPort 2.0 ports. The FirePro’s 2 GB GDDR5 memory is minuscule next to the Arc’s 8 GB GDDR6, but for legacy professional workloads tied to GCN 1.0-era software, the FirePro remains a functional, if dated, option.

Architecture Differences

The architectural gap between these two GPUs is vast and explains the benchmark results. The Intel Arc A750 uses the DG2-512 chip built on TSMC’s 6 nm process, with 21,700 million transistors packed into a 406 mm² die. That yields a transistor density of 53.4 million per square millimeter. The Xe-HPG architecture is designed for modern DirectX 12 Ultimate and Vulkan 1.4 workloads, with dedicated ray tracing cores (28 of them) and support for hardware-accelerated features like mesh shaders. The FirePro D300, in contrast, uses AMD’s Pitcairn chip on a 28 nm process, with a mere 2,800 million transistors spread over 212 mm², giving a transistor density of 13.2 million per square millimeter. Its GCN 1.0 architecture predates ray tracing, tensor cores, and modern API features; it maxes out at DirectX 12 (11_1) and Vulkan 1.2.170.

The shader configuration tells the same story. The Arc A750 has 3,584 shading units, 224 texture mapping units, and 112 ROPs, plus 28 ray tracing cores. The FirePro D300 has 1,280 shading units, 80 TMUs, and 32 ROPs, with no ray tracing hardware at all. Clock speeds also diverge sharply: the Arc runs at a 2050 MHz base and 2400 MHz boost, while the FirePro’s clock fields are null in the data, indicating that its operating frequencies are either unlisted or not officially specified. Memory architecture differs as well: the Arc uses 8 GB of GDDR6 on a 256-bit bus at 2000 MHz (16 Gbps effective) for 512.0 GB/s bandwidth, whereas the FirePro uses 2 GB of GDDR5 on a 256-bit bus at 1270 MHz (5.1 Gbps effective) for just 162.6 GB/s. The result is a 3.1x bandwidth advantage for Intel.

Head-to-Head Benchmarks

The two recorded head-to-head benchmarks are unambiguous. In Geekbench OpenCL, the Intel Arc A750 scores 98,554 against the FirePro D300’s 19,515, a delta of 405%. This is not a close contest; the Intel card is roughly five times faster in raw compute throughput. The Arc’s FP32 performance is 17.20 TFLOPS versus the FirePro’s 2.176 TFLOPS, which is an 8x gap in theoretical floating-point capacity. The Arc also has a 2:1 FP16 ratio at 34.41 TFLOPS, a feature the FirePro lacks entirely. In Geekbench Vulkan, the Arc scores 85,631 versus the FirePro’s 19,759, a 333.4% delta. Vulkan is a modern API, and the FirePro’s older GCN 1.0 architecture is clearly less efficient at handling it, even though both cards support it.

Looking at the broader benchmark suite, the Arc A750’s Passmark G3D score of 12,534 is particularly strong, and its Passmark GPU Compute score of 5,368 indicates solid general-purpose compute. The FirePro has no comparable data, so we cannot compute a direct delta, but the Geekbench results alone are sufficient to establish the hierarchy. The Arc’s 3DMark Steel Nomad DX12 score of 2,612 further reinforces its modern gaming capability, a workload the FirePro cannot even attempt in the recorded data. The nearest rival data for the Arc shows it trading blows with the Intel Arc B570 (0.1% delta) and NVIDIA GeForce RTX 3070 Mobile (0.2% delta), while the FirePro’s nearest rivals include the NVIDIA Quadro K5200 (0.2% delta) and AMD Radeon RX 6650 XT (-0.6% delta). These rival lists place both cards in similar overall percentile territory, but the individual test scores reveal that the Arc’s performance is far more consistent and modern.
