AMD Instinct MI350X and Intel Arc B570 occupy entirely different positions in the hardware landscape. The MI350X is an OAM-module accelerator with no display outputs, built for compute density, while the B570 is a dual-slot consumer graphics card with full display connectivity. The recorded data shows no shared benchmark suite, as the MI350X has no benchmark entries in the database, while the B570 has ten recorded tests. The MI350X sits at the 50th percentile among all GPUs, whereas the B570 reaches the 65th percentile. The B570’s average benchmark score is 20,556, which places it within a tight cluster of rivals: the NVIDIA GeForce RTX 3070 Mobile scores 20,534 (0.1% difference), the Intel Arc A750 scores 20,582 (0.1% lower), the NVIDIA Quadro M4000M scores 20,480 (0.4% higher), and the AMD Radeon R9 M390X scores 20,662 (0.5% lower). These deltas are all within a single percentage point, indicating that the B570’s measured performance is statistically indistinguishable from those four competitors.

Where Each One Wins

The AMD Instinct MI350X wins decisively in raw compute throughput and memory bandwidth. Its FP32 performance is 72.09 TFLOPS, and its FP16 performance is also 72.09 TFLOPS at a 1:1 ratio. The Intel Arc B570 delivers 11.52 TFLOPS FP32 and 23.04 TFLOPS FP16 at a 2:1 ratio. The MI350X’s FP32 figure is more than six times higher, and its FP16 figure is roughly three times higher. Texture rate follows a similar pattern: the MI350X reaches 2,252.8 GTexel/s versus 360.0 GTexel/s for the B570. Memory bandwidth is another categorical win: 8.19 TB/s for the MI350X against 380.0 GB/s for the B570, a difference of over twenty times. The MI350X also carries 288 GB of HBM3e memory, while the B570 has 10 GB of GDDR6.

The Intel Arc B570 wins in pixel throughput and graphics-specific features. Its pixel rate is 200.0 GPixel/s, whereas the MI350X records 0 MPixel/s, reflecting the latter’s lack of rasterization hardware. The B570 has 80 ROPs; the MI350X has none listed. The B570 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the MI350X lists N/A for all three APIs. The B570 also has 18 ray tracing cores, a feature entirely absent from the MI350X’s specification sheet. For any workload involving graphics rendering, ray tracing, or display output, the B570 is the only viable option in this comparison. For compute workloads that scale with shader count and memory bandwidth, the MI350X dominates.

The B570’s benchmark results show strengths in specific tests. Its highest recorded score is 96,844 in Geekbench Vulkan, followed by 83,514 in Geekbench OpenCL. In Passmark tests, it scores 14,195 in G3D, 7,281 in GPU Compute, 164 in DirectX 9, 118 in DirectX 11, 72 in DirectX 12, 65 in DirectX 10, and 661 in G2D. The 3DMark Steel Nomad DX12 score is 2,649. No comparative data exists for the MI350X, so the wins here are architectural rather than measured.

Architecture Differences

The two chips are built on different manufacturing nodes and foundries. The MI350X uses a 3 nm process at TSMC, while the B570 uses a 5 nm process, also at TSMC. Transistor counts differ substantially: the MI350X has 185,000 million transistors on a 2,380 mm² die, yielding a density of 77.7 million transistors per square millimeter. The B570 has 19,600 million transistors on a 272 mm² die, with a density of 72.1 million per square millimeter. The MI350X’s die is nearly nine times larger, and its transistor count is over nine times higher. Despite having slightly higher density, the MI350X’s scale is fundamentally different.

The compute architectures are unrelated. The MI350X uses CDNA 4.0 with the MI350 256CU chip, while the B570 uses Xe2-HPG with the BMG-G21 chip. The MI350X belongs to the Instinct (MIx) generation, and its predecessor is Radeon Instinct. The B570 belongs to the Battlemage (Arc 5) generation, and its predecessor is Alchemist. Shading unit counts reflect their divergent purposes: 16,384 shading units on the MI350X versus 2,304 on the B570. Texture mapping units number 1,024 on the MI350X versus 144 on the B570. The MI350X has no ROPs, no ray tracing cores, and no listed tensor cores. The B570 has 80 ROPs and 18 ray tracing cores.

Memory subsystems are entirely different. The MI350X uses 288 GB of HBM3e on an 8,192-bit bus, with memory clocked at 2000 MHz (8 Gbps effective) and bandwidth of 8.19 TB/s. The B570 uses 10 GB of GDDR6 on a 160-bit bus, with memory clocked at 2375 MHz (19 Gbps effective) and bandwidth of 380.0 GB/s. The memory bus width difference is 51 times, and the bandwidth difference is roughly 21 times. Power consumption reflects these disparities: the MI350X has a TDP of 1000 W and requires a 1400 W suggested PSU, while the B570 has a TDP of 150 W and a 450 W suggested PSU. The MI350X uses no power connectors, as it is an OAM module, whereas the B570 uses a single 8-pin connector.

Physical dimensions and interfaces also differ. The MI350X measures 102 mm in length and 165 mm in width, with a slot width of OAM Module. The B570 measures 272 mm in length and 115 mm in height, with a dual-slot form factor. The MI350X uses PCIe 5.0 x16, while the B570 uses PCIe 4.0 x8. The MI350X has no display outputs; the B570 offers 1x HDMI 2.1a and 3x DisplayPort 2.1. Clock behavior varies as well: the MI350X has a base clock of 1000 MHz and a boost clock of 2200 MHz, while the B570 has a fixed clock of 2500 MHz for both base and boost. Release dates are separated by roughly five months: the MI350X launched on 2025-06-11, and the B570 on 2025-01-15.

The Verdict

The data indicates that these products serve mutually exclusive purposes. The AMD Instinct MI350X is a compute accelerator with no graphics pipeline. Its 72.09 TFLOPS FP32, 72.09 TFLOPS FP16, and 8.19 TB/s bandwidth are designed for large-scale numerical workloads, but its lack of ROPs, pixel rate of 0 MPixel/s, and N/A API support make it unusable for rendering. The Intel Arc B570 is a consumer graphics card with full API support, ray tracing cores, and display outputs. Its 11.52 TFLOPS FP32 and 380.0 GB/s bandwidth are modest by comparison, but it delivers a complete graphics feature set.

For compute-centric tasks such as matrix operations, high-bandwidth data processing, or large memory footprint workloads, the MI350X is the clear choice based on its specifications. The 288 GB memory capacity alone exceeds the B570’s 10 GB by a factor of nearly 29. For graphics rendering, gaming, or any workload requiring a display, the B570 is the only option, as the MI350X cannot output video. The B570’s benchmark scores place it in a narrow competitive band: its average score of 20,556 is within 0.5% of four nearby rivals, indicating that its performance is comparable to mid-range mobile and desktop GPUs from the previous generation. The MI350X has no recorded benchmarks, so its relative performance can only be inferred from its architectural specifications.

The B570’s percentile ranking at 65 versus the MI350X’s 50 suggests that, among all GPUs in the database, the B570 outperforms a larger fraction of the field. However, the MI350X’s percentile of 50 with an average benchmark score of 0 likely reflects the lack of test data rather than actual performance. The MI350X’s release date of 2025-06-11 is later than the B570’s 2025-01-15, indicating a more recent introduction. The B570 has a launch MSRP of 219 USD, which can be stated once as a reference point. The MI350X has no launch MSRP listed.
