Intel Arc Pro B70 vs NVIDIA GB10 Comparison

Head-to-Head Benchmarks

The Intel Arc Pro B70 and NVIDIA GB10 occupy very different positions in the recorded benchmark data. The GB10 has an average benchmark score of 117,393 across two tests, while the Arc Pro B70 has no recorded benchmark scores in the database. This absence of data for the Intel card means there are no direct head-to-head comparisons available, but the GB10's percentile ranking of 95 versus the Arc Pro B70's 50th percentile provides a clear positional gap.

The NVIDIA GB10 delivers 120,137 in Geekbench OpenCL and 114,648 in Geekbench Vulkan. The OpenCL result sits 4.8% above the Vulkan score, indicating solid cross-API consistency. The GB10's nearest rivals in the database include the NVIDIA RTX 4000 SFF Ada Generation at 117,088 (0.3% ahead of it), the AMD Radeon PRO W7700 at 118,976 (1.3% behind it), the NVIDIA Tesla V100 SXM2 16 GB at 114,395 (2.6% ahead of it), and the NVIDIA RTX A5500 Mobile at 113,944 (3% ahead of it). These margins are tight, with the GB10 effectively trading blows with professional workstation cards.

The Intel Arc Pro B70, by contrast, has no benchmark entries and no nearest rivals listed. Its 50th percentile versus all GPUs suggests mid-pack positioning, but without recorded scores, the data cannot confirm actual performance levels. The GB10's 95th percentile places it in the top tier of all GPUs tracked by the database.

The compute throughput figures tell a more detailed story. The GB10 reaches 29.71 TFLOPS FP32, while the Arc Pro B70 achieves 22.94 TFLOPS FP32, a 29.5% advantage for the NVIDIA part. In FP16, the GB10 maintains the same 29.71 TFLOPS with a 1:1 ratio, whereas the Arc Pro B70 reaches 45.88 TFLOPS with a 2:1 ratio. The Intel card's FP16 figure exceeds the GB10's by 54.4%, though this comes from the 2:1 packed rate rather than native throughput. Texture rate favors the GB10 at 928.5 GTexel/s versus 716.8 GTexel/s for the Arc Pro B70, a 29.5% gap that mirrors the FP32 difference. Pixel rate, however, goes the other way: the Arc Pro B70 delivers 358.4 GPixel/s against 116.1 GPixel/s for the GB10, a 208.7% advantage for Intel.

Where Each One Wins

The NVIDIA GB10 wins decisively in raw compute workloads. Its 29.71 TFLOPS FP32 and 29.71 TFLOPS FP16 place it ahead of the Arc Pro B70 in general shader work. The 6144 shading units on the GB10 outnumber the 4096 on the Intel card, and the 384 texture mapping units surpass the 256 on the Arc Pro B70. The GB10 also carries 384 tensor cores, which the Intel card lacks entirely, giving it a clear edge in AI and machine learning inference tasks. The 48 RT cores on the GB10 exceed the 32 on the Arc Pro B70, suggesting stronger ray tracing throughput, though no ray tracing benchmarks appear in the data.

The Intel Arc Pro B70 wins in memory capacity and bandwidth. Its 32 GB of GDDR6 on a 256-bit bus delivers 608.0 GB/s, more than double the 273.2 GB/s of the GB10's LPDDR5X on a 256-bit bus. The GB10 offers 128 GB of memory, which is four times the capacity of the Intel card, but the bandwidth gap means the Arc Pro B70 can move data at 2.2 times the rate. For pixel-heavy workloads, the Arc Pro B70's 358.4 GPixel/s versus 116.1 GPixel/s gives it a 208.7% advantage in fill-rate-bound scenarios.

The GB10's display output is limited to a single HDMI port, while the Arc Pro B70 provides 1x HDMI 2.1a and 3x DisplayPort 2.1. The Intel card supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the GB10 lists N/A for all three APIs. This makes the Arc Pro B70 the only one of the two with consumer graphics API support. The GB10's production status is Active, while the Arc Pro B70 has no recorded production status.

Architecture Differences

The two GPUs come from different architectural families and serve different design goals. The Intel Arc Pro B70 uses the BMG-G31 chip built on the Xe2-HPG architecture, part of the Battlemage (Pro Series) generation. The NVIDIA GB10 uses the GB20B chip on the Blackwell 2.0 architecture, part of the Server Blackwell (Bxx) generation. Both use a 5 nm process node from TSMC, and the die sizes are close: 368 mm² for the Intel chip and 382 mm² for the NVIDIA chip, a 3.8% difference.

The transistor counts for both are listed as unknown, so die size alone cannot indicate density. The Intel architecture is oriented toward graphics and professional rendering, as shown by its full API support and multiple display outputs. The NVIDIA architecture is server-oriented, with no DirectX, OpenGL, or Vulkan support listed and a single HDMI output. The GB10's predecessor is listed as Server Hopper and its successor as Server Rubin, confirming its data center lineage.

The memory subsystems diverge sharply. The Arc Pro B70 uses GDDR6 with a 2375 MHz clock (19 Gbps effective) and a 256-bit bus. The GB10 uses LPDDR5X with a 1067 MHz clock (8.5 Gbps effective) and a 256-bit bus. The Intel card's memory clock is 2.2 times higher, and its effective data rate is 2.2 times higher, leading to the 608.0 GB/s versus 273.2 GB/s bandwidth gap. The GB10 compensates with 128 GB of capacity versus 32 GB, a 4x difference.

The rendering pipelines differ in structure. The Arc Pro B70 has 4096 shading units, 256 TMUs, 128 ROPs, and 32 RT cores. The GB10 has 6144 shading units, 384 TMUs, 48 ROPs, 48 RT cores, and 384 tensor cores. The GB10's ROP count is only 37.5% of the Intel card's, which explains the pixel rate gap. The tensor core presence on the GB10 is the most significant architectural differentiator, as the Intel card has no tensor cores listed.

Specification Differences

The clock speeds differ substantially. The Arc Pro B70 has a base clock of 2280 MHz and a boost clock of 2800 MHz. The GB10 has a base clock of 1665 MHz and a boost clock of 2418 MHz. The Intel card's base clock is 36.9% higher and its boost clock is 15.8% higher. The memory clocks differ as noted: 2375 MHz for the Intel card versus 1067 MHz for the NVIDIA card.

The power profiles are opposite. The Arc Pro B70 has a TDP of 230 W, requires a 1x 8-pin power connector, and lists a suggested PSU of 550 W. The GB10 has a TDP of 140 W, requires no power connectors, and lists a suggested PSU of 300 W. The NVIDIA part draws 39.1% less power. The Intel card is dual-slot with dimensions of 267 mm length, 110 mm height, and 39 mm width. The GB10 is an IGP (integrated graphics processor) form factor with dimensions of 150 mm length, 51 mm height, and 150 mm width.

The release dates differ by about five months. The GB10 launched on 2025-10-14, while the Arc Pro B70 launched on 2026-03-25. The launch MSRP for the Arc Pro B70 is 949 USD, and for the GB10 it is 3,999 USD. The GB10's bus interface is PCIe 5.0 x16, matching the Arc Pro B70's PCIe 5.0 x16 interface. The GB10 lists its production status as Active, while the Arc Pro B70 has no production status recorded.

The shading unit count, TMU count, ROP count, RT core count, and tensor core count all differ as described. The FP32 and FP16 throughput figures differ, with the GB10 ahead in FP32 and the Arc Pro B70 ahead in FP16 via the 2:1 packed rate. The pixel rate and texture rate also differ, with Intel ahead in pixel rate and NVIDIA ahead in texture rate. The display outputs differ: 1x HDMI 2.1a and 3x DisplayPort 2.1 for Intel versus 1x HDMI for NVIDIA. The API support differs entirely, with Intel supporting DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while NVIDIA lists N/A for all.
