Intel Arc B770 vs NVIDIA RTX PRO 6000D Blackwell Max-Q Comparison

# Intel Arc B770 vs NVIDIA RTX PRO 6000D Blackwell Max-Q

The database record places these two graphics cards in very different tiers, despite both being built on TSMC's 5 nm process. The Intel Arc B770 is a Battlemage-generation part with a 368 mm² die, while the NVIDIA RTX PRO 6000D Blackwell Max-Q uses a 750 mm² GB202 chip with 92,200 million transistors. The benchmark data shows the NVIDIA card achieving a 3DMark Steel Nomad DX12 score of 11088, with its nearest rival being the RTX PRO 6000 Blackwell Max-Q at the same score, while the Intel card has no recorded benchmark entries in this database. The specification gap between them is substantial across nearly every measurable category.

Where Each One Wins

The RTX PRO 6000D Blackwell Max-Q wins decisively in raw compute throughput. Its FP32 performance of 110.1 TFLOPS dwarfs the Arc B770's 19.66 TFLOPS, representing a 5.6x advantage. The texture rate tells a similar story: 1,720.6 GTexel/s versus 614.4 GTexel/s, a 2.8x gap. Pixel rate also favors NVIDIA at 439.3 GPixel/s against Intel's 307.2 GPixel/s, a 1.4x margin.

Memory capacity and bandwidth are where the NVIDIA card pulls even further ahead. The RTX PRO 6000D ships with 96 GB of GDDR7 on a 512-bit bus, delivering 1.79 TB/s. The Arc B770 has 16 GB of GDDR6 on a 256-bit bus, yielding 512.0 GB/s. That is a 3.5x bandwidth advantage and a 6x capacity advantage for NVIDIA. For large datasets, model loading, or high-resolution texture workloads, the NVIDIA card operates in a different class.

The Arc B770 does hold advantages in specific areas. Its base clock of 2100 MHz exceeds NVIDIA's 1590 MHz base clock, and its boost clock of 2400 MHz beats the RTX PRO 6000D's 2288 MHz. The Intel card also draws less power at 225 W versus 300 W, and it uses a 1x 6-pin plus 1x 8-pin connector arrangement compared to NVIDIA's single 16-pin. The suggested PSU for Intel is 550 W versus 700 W for NVIDIA. In efficiency per watt for raw clock speed, the Intel design appears more conservative in power draw while running higher clocks.

Architecture Differences

The two cards come from fundamentally different architecture lineages. Intel uses Xe2-HPG, the second generation of its high-performance graphics architecture, built for the Battlemage generation (Arc 7). NVIDIA uses Blackwell 2.0, its latest professional workstation architecture, designated as Blackwell PRO W (x000). Both are fabricated on TSMC's 5 nm node, but the die sizes diverge sharply: Intel's BMG-G31 measures 368 mm², while NVIDIA's GB202 measures 750 mm², nearly double the silicon area.

The transistor counts are not comparable. The database lists the Arc B770's transistor count as unknown, while the RTX PRO 6000D has 92,200 million transistors, yielding a density of 122.9M per mm². This massive transistor budget allows NVIDIA to field 24,064 shading units, 752 TMUs, and 192 ROPs. Intel fields 4,096 shading units, 256 TMUs, and 128 ROPs. The NVIDIA card also has 188 RT cores and 752 tensor cores, while Intel's card lists 32 RT cores and no tensor core entry.

Memory technology differs completely. The Arc B770 uses GDDR6 with a 2000 MHz memory clock (16 Gbps effective), while the RTX PRO 6000D uses GDDR7 with a 1750 MHz memory clock (28 Gbps effective). The GDDR7's higher data rate per pin, combined with the wider 512-bit bus, produces the 1.79 TB/s bandwidth figure. The Intel card's 256-bit bus with GDDR6 tops out at 512.0 GB/s.

The bus interface also separates the two. Intel uses PCIe 4.0 x16, while NVIDIA uses PCIe 5.0 x16, doubling the available host interface bandwidth. Display outputs differ as well: Intel provides 1x HDMI 2.1a and 3x DisplayPort 2.1, while NVIDIA provides 4x DisplayPort 2.1b with no HDMI port.

Head-to-Head Benchmarks

The database contains a single benchmark entry for the RTX PRO 6000D Blackwell Max-Q: a 3DMark Steel Nomad DX12 score of 11088. The Intel Arc B770 has no benchmark entries listed, so direct head-to-head comparison relies on the NVIDIA card's nearest rivals. The RTX PRO 6000D's closest competitor is the NVIDIA RTX PRO 6000 Blackwell Max-Q with the identical score of 11088, a delta of 0%. The AMD Radeon RX 550 scores 11075, which is 0.1% behind. The NVIDIA GeForce GTX 1650 SUPER scores 11047, 0.4% behind. The AMD FirePro W4300 scores 11225, which is 1.2% ahead of the RTX PRO 6000D.

These near-identical scores place the RTX PRO 6000D in a peculiar position: its 110.1 TFLOPS compute and 1.79 TB/s bandwidth do not translate into a dominant 3DMark result against much older, lower-spec cards. The 0.1% gap to the RX 550 and the 0.4% gap to the GTX 1650 SUPER suggest that this particular benchmark workload does not stress the NVIDIA card's unique capabilities, or that the Max-Q variant is power-limited in ways that constrain its performance. The Intel Arc B770, with no recorded benchmark, cannot be positioned against these scores, but its 19.66 TFLOPS FP32 and 512.0 GB/s bandwidth would likely place it far below the 11088 region if the same test were applied.

The only recorded win belongs to the RTX PRO 6000D by virtue of having a benchmark score at all. The wins counter in the database shows 0 wins for Intel and 0 wins for NVIDIA, reflecting the absence of head-to-head benchmark entries. The percentile ranking for both cards is 50, which indicates median placement among all GPUs in the database, though this is based on sparse data for the NVIDIA card and no data for the Intel card.

The Verdict

The data indicates a clear segmentation: the RTX PRO 6000D Blackwell Max-Q is built for compute-heavy, memory-hungry professional workloads, while the Arc B770 targets a lower power envelope and moderate performance tier. The NVIDIA card's 96 GB memory capacity and 1.79 TB/s bandwidth suit large model inference or massive texture datasets, while its 110.1 TFLOPS FP32 and 110.1 TFLOPS FP16 (1:1) support both single-precision and half-precision compute without throughput loss.

The Arc B770, with its 16 GB GDDR6 and 19.66 TFLOPS, fits a different use case. Its higher base and boost clocks relative to NVIDIA's Max-Q variant suggest a design tuned for consistent clock delivery rather than raw throughput. The 2:1 FP16 ratio means half-precision performance is doubled to 39.32 TFLOPS, but that remains far below NVIDIA's 110.1 TFLOPS FP16.

The benchmark data complicates the NVIDIA card's narrative. A 11088 score in 3DMark Steel Nomad DX12 places it essentially level with the RX 550, GTX 1650 SUPER, and FirePro W4300, all of which have far lower compute specifications. The 1.2% lead held by the FirePro W4300 over the RTX PRO 6000D indicates that this specific test does not reward the NVIDIA card's architectural strengths. The Intel card has no recorded score, so its actual performance remains unmeasured in this database.

For buyers selecting between these two, the choice depends on workload. The RTX PRO 6000D, with its 8,565 USD launch MSRP, active production status, and PCIe 5.0 interface, addresses professional environments requiring maximum memory and compute. The Arc B770, with no launch MSRP recorded and a 225 W TDP, suits systems with lower power budgets and modest compute demands. The 300 W TDP and 700 W suggested PSU for NVIDIA indicate a heavier power footprint, while Intel's 550 W suggestion leaves more room for other components. The data does not support a single winner; it supports two different purposes.
