AMD Instinct MI325X vs Intel Arc B570 Comparison

Head-to-Head Benchmarks

The recorded data for the AMD Instinct MI325X contains no benchmark entries, while the Intel Arc B570 has ten recorded benchmark results. This asymmetry makes a direct score-for-score comparison impossible. The Arc B570's average benchmark score is 20,556, placing it in the 65th percentile of all GPUs in the database. Its nearest rivals in the database include the NVIDIA GeForce RTX 3070 Mobile, which sits 0.1% higher in average score, and the Intel Arc A750, which sits 0.1% lower. The AMD Instinct MI325X holds a 50th percentile ranking among all GPUs, but with an average benchmark score of zero and no recorded entries, there is no measurable performance data to compare against the Arc B570's results.

The Intel Arc B570's strongest recorded result is in Geekbench Vulkan, where it scores 96,844. Its OpenCL score of 83,514 indicates a lower result in that API. In PassMark tests, the B570 produces a G3D score of 14,195, a GPU compute score of 7,281, and a G2D score of 661. DirectX results in PassMark are lower: DirectX 11 scores 118, DirectX 9 scores 164, DirectX 12 scores 72, and DirectX 10 scores 65. The 3DMark Steel Nomad DX12 result is 2,649. These figures establish a baseline for the B570 but offer no counterpart from the MI325X.

Architecture Differences

The AMD Instinct MI325X uses the CDNA 3.0 architecture, built on the Aqua Vanjaram chip. The Intel Arc B570 uses the Xe2-HPG architecture, built on the BMG-G21 chip. Both are manufactured on a 5 nm process at TSMC, but the similarity ends there. The MI325X integrates 153,000 million transistors on a 1017 mm² die, yielding a transistor density of 150.4M per mm². The Arc B570 integrates 19,600 million transistors on a 272 mm² die, for a density of 72.1M per mm². The MI325X's die is roughly 3.7 times larger and holds roughly 7.8 times more transistors.

Memory architecture differs substantially. The MI325X ships with 256 GB of HBM3e memory on an 8192-bit bus, delivering 6.14 TB/s of bandwidth. The Arc B570 ships with 10 GB of GDDR6 memory on a 160-bit bus, delivering 380.0 GB/s. The MI325X's memory bandwidth is over 16 times higher. Shader resources are also far apart: the MI325X has 19,456 shading units and 1,216 texture mapping units, while the Arc B570 has 2,304 shading units, 144 TMUs, and 80 ROPs. The MI325X lists zero ROPs and a pixel rate of 0 MPixel/s, which reflects its compute-focused design without a display output path. The Arc B570 has a pixel rate of 200.0 GPixel/s and a texture rate of 360.0 GTexel/s. The MI325X achieves a texture rate of 2,553.6 GTexel/s.

Compute throughput shows the intended use cases. The MI325X delivers 81.72 TFLOPS of FP32 and the same 81.72 TFLOPS of FP16 at a 1:1 ratio. The Arc B570 delivers 11.52 TFLOPS of FP32 and 23.04 TFLOPS of FP16 at a 2:1 ratio. The MI325X has roughly 7 times the FP32 throughput and roughly 3.5 times the FP16 throughput. The Arc B570 includes 18 ray tracing cores; the MI325X lists none. Clock behavior differs: the MI325X runs at a 1000 MHz base and 2100 MHz boost, while the Arc B570 runs at a flat 2500 MHz for both base and boost.

Thermal and power specifications reflect the scale gap. The MI325X has a TDP of 1000 W and a suggested PSU of 1400 W. The Arc B570 has a TDP of 150 W and a suggested PSU of 450 W. The MI325X uses an OAM module slot width with no power connectors, while the Arc B570 is a dual-slot card with a single 8-pin connector. The MI325X has no display outputs; the Arc B570 has one HDMI 2.1a port and three DisplayPort 2.1 outputs. API support confirms the split: the MI325X lists N/A for DirectX, OpenGL, and Vulkan, while the Arc B570 lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

The data separates these two GPUs into distinct categories. The AMD Instinct MI325X is an accelerator-class compute module with no display outputs, no graphics API support, and an OAM form factor. Its specifications point toward high-throughput compute workloads: 256 GB of HBM3e, 6.14 TB/s bandwidth, 81.72 TFLOPS of FP32, and a 1000 W TDP. The Intel Arc B570 is a consumer graphics card with a dual-slot design, display outputs, full DirectX 12 Ultimate support, and a 150 W TDP.

The Arc B570 has recorded benchmark results and a 65th percentile ranking, with an average score of 20,556. The MI325X has no recorded benchmark scores and sits at the 50th percentile with an average score of zero. The database contains no head-to-head benchmark entries between the two, so no measured comparison of real-world performance exists. What the data does show is an architectural divide: the MI325X prioritizes memory capacity, memory bandwidth, and raw FP32 throughput; the Arc B570 prioritizes rendering features, API compatibility, and power efficiency.

The MI325X's 153,000 million transistors and 1017 mm² die place it in a different class than the Arc B570's 19,600 million transistors and 272 mm² die. The MI325X's FP16 throughput matches its FP32 throughput at 81.72 TFLOPS, indicating a design tuned for lossless FP16 compute. The Arc B570's FP16 rate of 23.04 TFLOPS at a 2:1 ratio indicates a consumer-oriented shader design. Neither card can substitute for the other in its primary role. The MI325X cannot drive a display or run DirectX workloads. The Arc B570 cannot match the MI325X's memory capacity or bandwidth.

Where Each One Wins

The AMD Instinct MI325X wins on every raw compute specification in the database. It offers more shading units (19,456 versus 2,304), more TMUs (1,216 versus 144), higher FP32 throughput (81.72 TFLOPS versus 11.52 TFLOPS), higher FP16 throughput (81.72 versus 23.04 TFLOPS), more memory (256 GB versus 10 GB), wider memory bus (8192 bit versus 160 bit), and higher memory bandwidth (6.14 TB/s versus 380.0 GB/s). It also has a higher texture rate (2,553.6 GTexel/s versus 360.0 GTexel/s) and a higher transistor count (153,000 million versus 19,600 million). Its PCIe 5.0 x16 interface outpaces the Arc B570's PCIe 4.0 x8 interface. Its release date of 2024-10-09 precedes the Arc B570's 2025-01-15 release.

The Intel Arc B570 wins on every client-oriented specification. It has 80 ROPs and a pixel rate of 200.0 GPixel/s, while the MI325X lists zero ROPs and a pixel rate of 0 MPixel/s. It includes 18 ray tracing cores; the MI325X lists none. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the MI325X lists N/A for all three. It provides one HDMI 2.1a and three DisplayPort 2.1 outputs; the MI325X has none. It runs at a higher clock speed (2500 MHz base and boost versus 1000 MHz base and 2100 MHz boost). It consumes far less power (150 W TDP versus 1000 W TDP) and requires a smaller PSU (450 W versus 1400 W). It is the only one of the two with recorded benchmark results, an average score of 20,556, and a 65th percentile ranking. Its launch MSRP is 219 USD, and it has an active production status.

The MI325X is the choice for compute-heavy environments where memory capacity and bandwidth dominate. The Arc B570 is the choice for graphics rendering, display output, and API-driven workloads. The recorded data offers no intersection between these two roles.
