Intel Arc B770 vs NVIDIA GB10 Comparison

The Intel Arc B770 and NVIDIA GB10 represent two vastly different approaches to GPU design, and the recorded data places them at opposite ends of the performance spectrum. The Arc B770, built on Intel's Xe2-HPG architecture, is a consumer-oriented graphics card with a 50th percentile ranking among all GPUs. The GB10, by contrast, is a server-focused accelerator built on Blackwell 2.0, achieving a 95th percentile ranking. The GB10 also has a substantial average benchmark score of 117,393, while the Arc B770 has no recorded benchmarks in the database, giving the NVIDIA part a clear statistical advantage.

Where Each One Wins

The benchmark data shows a decisive split in favor of the NVIDIA GB10. The Arc B770 has zero recorded benchmark wins, while the GB10 has two recorded tests: Geekbench OpenCL with a score of 120,137 and Geekbench Vulkan with a score of 114,648. These results confirm the GB10's dominance in compute-heavy workloads, as both tests rely heavily on raw shader throughput and memory bandwidth. The Arc B770, lacking any benchmark entries, cannot claim a single victory in the database, and its 50th percentile ranking reinforces that it sits in the middle of the pack rather than at the top.

The use-case split is therefore clear. The GB10 is designed for tasks where massive parallel compute is essential, such as server-side inference or professional rendering, and its benchmark scores support this positioning. The Arc B770, with no recorded scores, is positioned as a general-purpose graphics card, but the data provides no evidence of it outperforming the GB10 in any measurable way. The wins category is entirely one-sided, with the GB10 taking both available tests and the Arc B770 recording none.

Architecture Differences

The architectural gap between these two GPUs is fundamental. The Arc B770 uses the BMG-G31 chip with Intel's Xe2-HPG architecture, part of the Battlemage generation, and it is fabricated on a 5 nm process at TSMC with a die size of 368 mm². The GB10 uses the GB20B chip with Blackwell 2.0 architecture, part of the Server Blackwell generation, also fabricated on a 5 nm process at TSMC but with a slightly larger die size of 382 mm². Both chips have unknown transistor counts, but the die size difference of 14 mm² suggests a modest increase in physical resources for the NVIDIA part.

The shading unit counts differ significantly. The GB10 packs 6144 shading units, 384 texture mapping units, and 48 render output units, while the Arc B770 has 4096 shading units, 256 TMUs, and 128 ROPs. This means the GB10 has 50% more shading units and 50% more TMUs, but the Arc B770 has nearly three times as many ROPs. The GB10 also includes 48 ray tracing cores and 384 tensor cores, whereas the Arc B770 has 32 ray tracing cores and no tensor cores listed. The GB10's tensor cores are critical for AI workloads, and their presence gives it a feature set the Arc B770 cannot match.

Clock speeds also differentiate the two. The Arc B770 runs at a base clock of 2100 MHz and a boost clock of 2400 MHz, while the GB10 runs lower at 1665 MHz base and 2418 MHz boost. Despite the lower base clock, the GB10's higher shading unit count drives its superior FP32 performance. The GB10 delivers 29.71 TFLOPS of FP32 compute, while the Arc B770 delivers 19.66 TFLOPS, a gap of roughly 10 TFLOPS. The FP16 results are more complex: the Arc B770 reaches 39.32 TFLOPS with a 2:1 ratio, while the GB10 also reaches 29.71 TFLOPS but with a 1:1 ratio, meaning it does not double FP16 throughput.

Head-to-Head Benchmarks

The only recorded head-to-head data comes from the GB10's benchmark scores, which the Arc B770 cannot contest. The GB10 achieves 120,137 in Geekbench OpenCL, a score that places it 0.3% ahead of the NVIDIA RTX 4000 SFF Ada Generation, which has an average score of 117,088. It also sits 1.3% behind the AMD Radeon PRO W7700, which scores 118,976, and 2.6% ahead of the NVIDIA Tesla V100 SXM2 16 GB, which scores 114,395. The GB10's average benchmark score of 117,393 puts it 3% ahead of the NVIDIA RTX A5500 Mobile, which scores 113,944.

The Geekbench Vulkan result of 114,648 is lower than the OpenCL score by 5,489 points, indicating that the GB10's performance varies somewhat by API. However, even this lower score remains competitive with its nearest rivals, as all four rivals have average scores between 113,944 and 118,976. The Arc B770, with no benchmarks, cannot be placed in this ranking, and the database shows zero wins for it, meaning there is no head-to-head comparison where it takes the lead. The GB10's margin over the Tesla V100 SXM2, a previous-generation server accelerator, is 2.6%, while its margin over the RTX A5500 Mobile is 3%, showing consistent superiority over older mobile parts.

Specification Differences

The specification table reveals stark contrasts in nearly every category. Memory is a major differentiator: the Arc B770 has 16 GB of GDDR6 memory on a 256-bit bus with 512.0 GB/s of bandwidth, while the GB10 has 128 GB of LPDDR5X memory on a 256-bit bus but with only 273.2 GB/s of bandwidth. The GB10 has eight times the capacity but less than half the bandwidth per gigabyte, reflecting its server-oriented design where capacity matters more than raw speed. The memory clock also differs, with the Arc B770 running at 2000 MHz (16 Gbps effective) and the GB10 running at 1067 MHz (8.5 Gbps effective).

Power consumption is another clear split. The Arc B770 has a TDP of 225 W, requires a 550 W suggested PSU, and uses dual-slot cooling with 1x 6-pin and 1x 8-pin power connectors. The GB10 has a TDP of 140 W, a 300 W suggested PSU, and uses an integrated graphics package (IGP) with no power connectors and no slot width beyond the board itself. The GB10's dimensions are listed as 150 mm by 51 mm by 150 mm, while the Arc B770 has no recorded dimensions, but the GB10's compact form factor and low power draw make it suitable for dense server deployments.

The bus interface also differs: the Arc B770 uses PCIe 4.0 x16, while the GB10 uses PCIe 5.0 x16, offering double the bandwidth for data transfer. Display outputs are minimal on both, but the Arc B770 provides 1x HDMI 2.1a and 3x DisplayPort 2.1, while the GB10 has only 1x HDMI. API support is a critical gap: the Arc B770 supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the GB10 lists N/A for all three, confirming it is not designed for consumer graphics rendering. The GB10 also has a production status of Active, while the Arc B770 has none recorded.

The Verdict

The data directs different buyers to each product. The NVIDIA GB10, with its 95th percentile ranking and average benchmark score of 117,393, is the clear choice for compute-intensive server workloads. Its 128 GB of memory, 384 tensor cores, and 29.71 TFLOPS of FP32 performance make it suitable for AI inference and large-scale data processing, and its 140 W TDP with no power connectors allows for dense integration. The Arc B770, by contrast, offers no recorded benchmarks and a 50th percentile ranking, but it provides 16 GB of GDDR6 memory, 512.0 GB/s of bandwidth, and full support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, making it a functional consumer graphics card for gaming and traditional rendering.

The GB10's release date of October 2025 precedes the Arc B770's December 2025 release by roughly two months, and its production status is Active, while the Arc B770 has no production status recorded. The GB10 also has a launch MSRP of 3,999 USD, a figure that reflects its server-class positioning. The Arc B770 has no launch MSRP in the database. For users needing raw compute and massive memory capacity, the GB10 wins outright. For users needing a conventional graphics card with standard display outputs and consumer API support, the Arc B770 is the only option that fits that role, though the data provides no performance evidence to recommend it over the GB10 in any compute task.
