AMD Radeon Pro Vega 16 vs Intel Arc A750 Comparison

Head-to-Head Benchmarks

The recorded data shows two shared benchmark tests between the AMD Radeon Pro Vega 16 and the Intel Arc A750: Geekbench OpenCL and Geekbench Vulkan. In both, the Intel Arc A750 wins decisively.

In Geekbench OpenCL, the AMD Radeon Pro Vega 16 scores 18,268 points, while the Intel Arc A750 scores 98,554 points. That is a delta of -81.5% from the AMD part's perspective, meaning the Intel card delivers roughly 5.4 times the OpenCL compute score. This is a massive gap, far beyond any run-to-run variance a reviewer might expect.

The Geekbench Vulkan result tells a similar story. The AMD Radeon Pro Vega 16 records 21,832 points, while the Intel Arc A750 records 85,631 points. The delta is -74.5%, placing the Intel part at nearly 4 times the Vulkan score. The AMD GPU's advantage in the broader database percentile ranking (68th percentile versus 66th) does not translate into any head-to-head win in these two tests.

The average benchmark score in the database favors the AMD part slightly. The Radeon Pro Vega 16 has an average benchmark score of 23,250, while the Intel Arc A750 sits at 20,582. That said, the two average scores are drawn from different benchmark suites. The AMD GPU's average is built from three Geekbench tests (Metal, OpenCL, Vulkan), while the Intel GPU's average includes 3DMark Steel Nomad DX12, Geekbench OpenCL and Vulkan, and multiple Passmark tests. The A750's 3DMark Steel Nomad DX12 score of 2,612 and its Passmark G3D score of 12,534 show a strong DirectX-focused result set, whereas the Radeon Pro Vega 16 has no DirectX benchmark in the database.

The nearest rival data reinforces the positioning. The Radeon Pro Vega 16 sits within 0.3% of the NVIDIA P106-100, the AMD Radeon RX 6600M, the AMD Radeon R9 M290X, and the AMD Radeon AI PRO R9700, all clustered around a 23,250 average score. The Intel Arc A750's nearest rivals include the Intel Arc B570 (0.1% ahead), the NVIDIA GeForce RTX 3070 Mobile (0.2% ahead), and the NVIDIA Quadro M4000M (0.5% behind). These are different performance strata, with the A750 competing against much faster company in raw compute terms.

Architecture Differences

The two GPUs come from entirely different design lineages. The AMD Radeon Pro Vega 16 uses the Vega 12 chip built on GCN 5.0 architecture, produced on a 14 nm process at GlobalFoundries. The Intel Arc A750 uses the DG2-512 chip built on Xe-HPG architecture, produced on a 6 nm process at TSMC. The process node difference alone, 14 nm versus 6 nm, explains much of the efficiency and density gap.

The Intel chip carries 21,700 million transistors on a 406 mm² die, with a transistor density of 53.4 million per square millimeter. The AMD chip's transistor count and die size are not recorded in the database, but the architectural leap is clear from the compute resources. The Intel Arc A750 has 3,584 shading units, 224 texture mapping units, and 112 raster operation pipelines. The AMD Radeon Pro Vega 16 has 1,024 shading units, 64 TMUs, and 32 ROPs. That is a 3.5x difference in shading units, a 3.5x difference in TMUs, and a 3.5x difference in ROPs.

The clock speeds also diverge sharply. The AMD part runs a base clock of 815 MHz and a boost clock of 1190 MHz. The Intel part runs a base clock of 2050 MHz and a boost clock of 2400 MHz. The higher clocks, combined with the larger shader array, produce an FP32 throughput of 17.20 TFLOPS for the Intel GPU versus 2.437 TFLOPS for the AMD GPU. FP16 throughput follows the same pattern: 34.41 TFLOPS for Intel, 4.874 TFLOPS for AMD, both at a 2:1 ratio.

Memory configuration is another major divider. The AMD Radeon Pro Vega 16 uses 4 GB of HBM2 on a 1024-bit bus, with memory clocked at 1200 MHz (2.4 Gbps effective) for a bandwidth of 307.2 GB/s. The Intel Arc A750 uses 8 GB of GDDR6 on a 256-bit bus, with memory clocked at 2000 MHz (16 Gbps effective) for a bandwidth of 512.0 GB/s. The AMD part has a wider bus, a legacy HBM2 advantage, but the Intel part has double the capacity, a newer memory type, and 67% more bandwidth.

The Intel GPU also includes 28 ray tracing cores, a feature the AMD part lacks entirely. The AMD GPU supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.3. The Intel GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The API generation difference matters for modern game workloads, especially with ray tracing and mesh shaders.

Power and physical design differ as well. The AMD Radeon Pro Vega 16 is rated at 75 W TDP and is an integrated form factor (IGP) with portable-device-dependent display outputs. The Intel Arc A750 is rated at 225 W TDP, uses a dual-slot design, requires one 6-pin and one 8-pin power connector, and carries a suggested 550 W power supply. The AMD part uses PCIe 3.0 x16, while the Intel part uses PCIe 4.0 x16. The Intel card has 1x HDMI 2.1 and 3x DisplayPort 2.0 outputs.

The Verdict

The data supports a clear split. In raw compute benchmarks, the Intel Arc A750 dominates the AMD Radeon Pro Vega 16. The OpenCL score is 98,554 versus 18,268, a 5.4x margin. The Vulkan score is 85,631 versus 21,832, a 3.9x margin. The Intel part also offers 8 GB of GDDR6 memory versus 4 GB of HBM2, higher bandwidth, more shading units, ray tracing hardware, and a newer API feature set.

The AMD Radeon Pro Vega 16 does hold a higher database percentile (68th versus 66th) and a higher average benchmark score (23,250 versus 20,582), but those figures are drawn from different test types. The AMD part's scores come entirely from Geekbench workloads, which do not include the DirectX or 3DMark tests where the Intel part posts strong numbers.

The power envelope tells the other side of the story. The AMD part is an integrated GPU at 75 W, designed for portable devices with no standalone power connectors. The Intel part is a 225 W dual-slot add-in card requiring a 550 W power supply. For a compact, low-power mobile system, the Radeon Pro Vega 16 is the only viable option in this pairing. For a desktop system with adequate power delivery, the Intel Arc A750 delivers far higher compute throughput, double the memory capacity, and dedicated ray tracing hardware.

The production status for both is end-of-life. The AMD GPU launched in November 2018, and the Intel GPU launched in October 2022. The Intel part has a recorded launch MSRP of 289 USD, which the database lists once, but the AMD part has no launch MSRP in the record. The Intel part's predecessor is listed as Xe Graphics, and its successor is Battlemage. The AMD part has no predecessor or successor listed.
