Intel Arc B770 vs NVIDIA B200 SXM6 Comparison

Head-to-Head Benchmarks

The database does not contain a direct head-to-head benchmark comparison between the Intel Arc B770 and the NVIDIA B200 SXM6. The recorded data includes no benchmark scores, no percentile comparisons, and no rival listings for either product. Consequently, the analysis below relies strictly on the architectural specifications and the capabilities these specifications imply, rather than measured performance deltas.

The raw compute figures from the specification sheets are the only quantitative starting point. The NVIDIA B200 SXM6 delivers 69.34 TFLOPS of FP32 throughput, while the Intel Arc B770 delivers 19.66 TFLOPS. That is a substantial gap, roughly 3.5 times the FP32 throughput in favor of the B200 SXM6. In FP16, the B200 SXM6 also produces 69.34 TFLOPS at a 1:1 ratio, whereas the Arc B770 reaches 39.32 TFLOPS via a 2:1 ratio. The B200 SXM6 still leads in raw FP16 compute, but the margin narrows to about 1.76 times.

Memory bandwidth separates the two even more dramatically. The B200 SXM6 has 8.19 TB/s of bandwidth across an 8192-bit HBM3e interface, while the Arc B770 has 512.0 GB/s across a 256-bit GDDR6 interface. That is a 16-fold difference in memory bandwidth. For workloads that saturate memory, such as large matrix operations or high-resolution rendering, the B200 SXM6 operates in a different class.

The Intel Arc B770 counters in pixel throughput. It records 307.2 GPixel/s, while the B200 SXM6 records 43.92 GPixel/s. That is a 7-fold advantage for the Arc B770 in rasterization throughput. Texture rate also favors the Arc B770: 614.4 GTexel/s versus 1,083.4 GTexel/s for the B200 SXM6. The B200 SXM6 leads texture rate by a factor of 1.76, but the Arc B770's pixel rate advantage indicates that its fixed-function output stages are designed for display-oriented workloads.

Architecture Differences

The two products come from different architectural families with different design goals. The Intel Arc B770 uses the BMG-G31 chip, built on the Xe2-HPG architecture, and belongs to the Battlemage (Arc 7) generation. The NVIDIA B200 SXM6 uses the GB100 chip, built on the Blackwell architecture, and belongs to the Server Blackwell (Bxx) generation. Both use a 5 nm process node from TSMC, but the similarities end there.

The B200 SXM6 is a massive die. Its 1628 mm² die size houses 208,000 million transistors, yielding a transistor density of 127.8M per mm². The Arc B770 has a 368 mm² die, with transistor count listed as unknown. The B200 SXM6's die is 4.4 times larger, and its transistor count dwarfs the Arc B770's unspecified figure. The B200 SXM6 is a server accelerator with an active production status, released in 2024, while the Arc B770 has a release date in 2025 and no production status listed.

The memory subsystems diverge completely. The B200 SXM6 uses 180 GB of HBM3e across an 8192-bit bus, with an effective memory clock of 2000 MHz and 8 Gbps effective speed. The Arc B770 uses 16 GB of GDDR6 across a 256-bit bus, with a 2000 MHz memory clock and 16 Gbps effective speed. The B200 SXM6 has over 11 times the memory capacity and 16 times the bandwidth.

The compute resources are also asymmetric. The B200 SXM6 has 18,944 shading units, 592 TMUs, 24 ROPs, and 592 tensor cores. The Arc B770 has 4,096 shading units, 256 TMUs, 128 ROPs, and 32 ray tracing cores. The B200 SXM6 has no listed ray tracing cores, and the Arc B770 has no listed tensor cores. The B200 SXM6's 592 tensor cores indicate an explicit focus on AI and deep learning workloads, while the Arc B770's 32 ray tracing cores serve real-time graphics rendering.

Clock behavior also differs. The B200 SXM6 has a base clock of 120 MHz and a boost clock of 1830 MHz. The Arc B770 has a base clock of 2100 MHz and a boost clock of 2400 MHz. The Arc B770's base clock is 17.5 times higher than the B200 SXM6's base clock, though the boost clocks are closer. The B200 SXM6 relies on its enormous parallel resources rather than high clock speeds.

The power envelopes are starkly different. The B200 SXM6 has a TDP of 1000 W and a suggested PSU of 1400 W. The Arc B770 has a TDP of 225 W and a suggested PSU of 550 W. The B200 SXM6 consumes over 4 times the power of the Arc B770, and its suggested PSU requirement is 2.5 times higher.

Where Each One Wins

The Intel Arc B770 is positioned for graphics output. It has display outputs: 1x HDMI 2.1a and 3x DisplayPort 2.1. The B200 SXM6 has no outputs at all. The Arc B770 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The B200 SXM6 lists N/A for all three graphics APIs. For any workload that requires rendering to a screen or a window, the Arc B770 is the only option between the two.

The Arc B770 also wins in pixel throughput. Its 307.2 GPixel/s versus the B200 SXM6's 43.92 GPixel/s means the Arc B770 can fill rasterized frames faster. The Arc B770's 128 ROPs, compared to the B200 SXM6's 24 ROPs, support this advantage. In a pure rasterization task, the Arc B770 has a decisive edge.

The NVIDIA B200 SXM6 wins in raw compute and memory capacity. Its 69.34 TFLOPS FP32 and FP16 throughput, its 180 GB of HBM3e, and its 8.19 TB/s bandwidth place it far ahead of the Arc B770 in any compute-heavy task. The B200 SXM6's 592 tensor cores and 18,944 shading units handle parallel workloads at a scale the Arc B770 cannot match. The B200 SXM6's PCIe 6.0 x16 interface also provides a newer bus standard than the Arc B770's PCIe 4.0 x16.

The B200 SXM6 has a higher texture rate, 1,083.4 GTexel/s versus 614.4 GTexel/s, which gives it an edge in texture-heavy compute workloads, though the Arc B770's pixel rate advantage means the B200 SXM6's texture rate is not paired with output capability.

The Verdict

The data describes two products with almost no overlap in intended use. The Intel Arc B770 is a consumer-oriented graphics card, evidenced by its display outputs, graphics API support, and dual-slot form factor. Its 307.2 GPixel/s pixel rate and 128 ROPs make it suitable for rendering tasks that output to a display. Its 16 GB of GDDR6 memory and 512.0 GB/s bandwidth are sufficient for standard gaming and workstation graphics workloads.

The NVIDIA B200 SXM6 is a server accelerator with no display outputs and no graphics API support. Its 180 GB of HBM3e, 8.19 TB/s bandwidth, and 69.34 TFLOPS FP32 compute are designed for data center compute tasks such as AI training or scientific simulation. The 592 tensor cores and PCIe 6.0 x16 interface reinforce this orientation. Its 1000 W TDP and SXM module slot width are not compatible with typical desktop builds.

Users who need a graphics card for rendering, gaming, or any workload requiring a display should select the Intel Arc B770. Users who need a high-throughput compute accelerator for server deployments should select the NVIDIA B200 SXM6, at a launch MSRP of 34,999 USD. The choice is not about one being better overall; the specifications indicate two different product categories. The Arc B770 wins on pixel rate, graphics output, and lower power consumption. The B200 SXM6 wins on compute throughput, memory capacity, memory bandwidth, texture rate, and tensor core availability. The recorded data provides no benchmark scores to compare them directly, so any selection should follow the workload requirements.
