Intel Arc B570 vs NVIDIA B300 SXM6 AC Comparison

Head-to-Head Benchmarks

The recorded database contains a single shared benchmark between the Intel Arc B570 and the NVIDIA B300 SXM6 AC: Geekbench OpenCL. In this test, the NVIDIA B300 SXM6 AC scores 369,831, while the Intel Arc B570 scores 83,514. The delta is stark, with the NVIDIA part leading by 77.4%. This is not a marginal gap; it represents a performance disparity of roughly 4.4 times in favor of the server accelerator.

The Intel Arc B570 posts an average benchmark score of 20,556 across its full suite of tests. The B300 SXM6 AC, with only one recorded benchmark, shows an average of 369,831. The percentile placement reinforces the divide: the B300 sits at the 100th percentile of all GPUs in the database, while the Arc B570 rests at the 65th percentile. In practical terms, the B300 is at the absolute ceiling of recorded performance, and the B570 sits comfortably in the upper-middle range.

The B570's nearest rivals in the database are instructive. It sits within 0.5% of the NVIDIA Quadro M4000M, the AMD Radeon R9 M390X, the NVIDIA GeForce RTX 3070 Mobile, and the Intel Arc A750. Its average score trails the Arc A750 by a mere 0.1% and leads the RTX 3070 Mobile by 0.1%. This positions the B570 as a mid-range contender, one that trades blows with a previous-generation mobile flagship and its own predecessor-tier desktop card. The B300, by contrast, leads the NVIDIA B200 by 7%, the NVIDIA H200 NVL by 10.4%, the AMD Instinct MI300X by 16.3%, and the NVIDIA L40S by 25%. Those deltas place it in a completely different competitive stratum, one defined by datacenter compute rather than consumer gaming.

The single head-to-head result, while limited in scope, is decisive. The B300 SXM6 AC wins the only direct comparison by 77.4%. No other overlapping test data exists in the database, so the analysis of relative performance rests on this one OpenCL measurement plus the broader average-score and rival comparisons. The data shows a clear hierarchy: the B300 is a top-of-database compute monster, and the B570 is a capable mainstream graphics card.

Architecture Differences

The two chips share a foundry and process node. Both are built by TSMC on a 5 nm process. That is where the architectural similarities end. The Intel Arc B570 uses the BMG-G21 chip, built on the Xe2-HPG architecture, part of the Battlemage (Arc 5) generation. The NVIDIA B300 SXM6 AC uses the GB110 chip, built on the Blackwell Ultra architecture, part of the Server Blackwell (Bxx) generation.

The transistor counts tell the scale story. The B300 packs 208,000 million transistors on a 1628 mm² die, yielding a transistor density of 127.8 million per mm². The B570 has 19,600 million transistors on a 272 mm² die, with a density of 72.1 million per mm². The B300 is an order of magnitude larger in both raw transistor count and physical silicon area. The density difference also indicates a more tightly packed design for the server part.

Memory configurations diverge sharply. The B570 uses 10 GB of GDDR6 on a 160-bit bus, delivering 380.0 GB/s of bandwidth. The B300 uses 288 GB of HBM3e on an 8192-bit bus, delivering 8.19 TB/s. That is more than 21 times the memory capacity and more than 21 times the bandwidth. The B300's memory clock is 2000 MHz (8 Gbps effective), while the B570's memory runs at 2375 MHz (19 Gbps effective). The B570's faster effective memory speed is irrelevant next to the B300's massive bus width and HBM3e stack.

Compute resources differ by similar magnitudes. The B570 has 2304 shading units, 144 texture mapping units, and 80 ROPs. The B300 has 18,944 shading units, 592 TMUs, and only 24 ROPs. The B300's low ROP count reflects its compute-first design; it is not built for rasterization-heavy graphics workloads. The B570 includes 18 ray tracing cores, while the B300 lists no RT cores. The B300 instead carries 592 tensor cores, a feature class the B570 does not list. The FP32 throughput reflects this split: the B300 delivers 76.99 TFLOPS, the B570 delivers 11.52 TFLOPS. The B300 also delivers FP16 at 76.99 TFLOPS (1:1 ratio), while the B570 achieves 23.04 TFLOPS (2:1 ratio).

Clock speeds run counter to the performance trend. The B570 has a base and boost clock of 2500 MHz, while the B300 has a base of 1665 MHz and a boost of 2032 MHz. The B570's higher clocks do not compensate for the B300's massive compute width. Pixel rate favors the B570 at 200.0 GPixel/s versus 48.77 GPixel/s for the B300, again confirming the raster-focused design of the Intel part. Texture rate favors the B300 at 1,202.9 GTexel/s versus 360.0 GTexel/s for the B570.

Power and physical format could not be more different. The B570 has a 150 W TDP, a dual-slot cooler, and a single 8-pin power connector, with a suggested 450 W PSU. The B300 has a 1100 W TDP, comes as an SXM Module, and has no listed power connectors, with a suggested 1500 W PSU. The B570 uses PCIe 4.0 x8; the B300 uses PCIe 6.0 x16. The B570 offers 1x HDMI 2.1a and 3x DisplayPort 2.1 outputs; the B300 has no display outputs. The B570 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4; the B300 lists N/A for all three graphics APIs.

The Verdict

The data tells a straightforward story. The NVIDIA B300 SXM6 AC is a server accelerator designed for maximum compute throughput, and the Intel Arc B570 is a consumer graphics card aimed at conventional rendering workloads. The 77.4% lead in Geekbench OpenCL, the 100th percentile ranking, and the 7% to 25% advantages over its nearest rivals all confirm the B300's position at the top of the database. The B570, with its 65th percentile ranking and its near-tie with the RTX 3070 Mobile and Arc A750, occupies a mid-range slot.

The B300's architecture prioritizes tensor throughput, FP32 and FP16 compute, and enormous memory bandwidth. Its lack of display outputs, its N/A graphics API status, and its 1100 W TDP make it unsuitable for desktop use. The B570, with its display outputs, DirectX 12 Ultimate support, and 150 W TDP, is a conventional graphics card. The B300 wins the only shared benchmark by a wide margin, and its average score is more than 17 times higher than the B570's. The B570 wins no head-to-head tests in the database.

For a buyer choosing between these two, the use case decides the outcome. The B300 is for datacenter compute, AI acceleration, and high-bandwidth server workloads. The B570 is for gaming, desktop graphics, and consumer rendering. The B300's 76.99 TFLOPS FP32 and 8.19 TB/s bandwidth dwarf the B570's 11.52 TFLOPS and 380.0 GB/s, but those figures matter only in the server context. The B570's 200.0 GPixel/s pixel rate and 18 RT cores make it the only one of the two with any relevance to rasterized graphics. The data does not suggest that one is "better" in absolute terms; it suggests that they are different tools for different jobs.
