Intel Arc Pro B65 vs NVIDIA RTX PRO 2000 Blackwell Comparison

Intel Arc Pro B65 and NVIDIA RTX PRO 2000 Blackwell are two professional workstation GPUs that take fundamentally different approaches to performance, memory, and power. The Intel part, based on the Xe2-HPG architecture with the BMG-G21 chip, emphasizes massive memory capacity and high clock speeds. The NVIDIA part, built on Blackwell 2.0 with the GB206 chip, counters with a much higher shading unit count and a lower power envelope. The recorded data shows the NVIDIA card holds a percentile rank of 70 among all GPUs, while the Intel card sits at the 50th percentile, indicating a significant gap in overall measured performance.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between these two specific cards. However, the NVIDIA RTX PRO 2000 Blackwell has a substantial set of individual benchmark scores, while the Intel Arc Pro B65 has no recorded benchmark entries. The NVIDIA card's average benchmark score is 25269 points, placing it at the 70th percentile of all GPUs. This score is derived from a range of tests including 3DMark Steel Nomad DX12 at 2374.5 points, Geekbench OpenCL at 106087 points, and Geekbench Vulkan at 113865 points.

PassMark results for the NVIDIA card show a G3D score of 20049 points and a GPU compute score of 8396 points. The NVIDIA card also records DirectX 9, 10, 11, and 12 scores of 241, 122, 174, and 80 points respectively, plus a G2D score of 1303 points. Without corresponding Intel benchmark data, a direct score-by-score comparison is impossible from the database.

The nearest rivals for the NVIDIA card provide context for its performance tier. The AMD Radeon RX 6700M averages 25633 points, which is 1.4% higher than the NVIDIA card. The AMD Radeon Pro W5700 averages 25626 points, also 1.8% higher. The NVIDIA GeForce RTX 3080 Ti Mobile averages 25740 points, again 1.8% higher. On the other side, the NVIDIA RTX A5000 Mobile averages 24763 points, which is 2% lower than the RTX PRO 2000 Blackwell. These deltas show the card sits in a tightly contested performance band, slightly below a cluster of mobile gaming and workstation parts but above the A5000 Mobile.

Where Each One Wins

The Intel Arc Pro B65 wins clearly in raw memory specifications. It carries 32 GB of GDDR6 memory on a 256 bit bus, yielding 608.0 GB/s of bandwidth. The NVIDIA RTX PRO 2000 Blackwell has 16 GB of GDDR7 memory on a 128 bit bus, producing 288.0 GB/s. That is a 2x advantage in capacity and more than a 2x advantage in bandwidth for the Intel card. The Intel card also runs its memory at 2375 MHz (19 Gbps effective) compared to 1125 MHz (18 Gbps effective) for NVIDIA.

The NVIDIA card wins in compute throughput per the specification sheet. It delivers 17.03 TFLOPS of FP32 performance, while the Intel card delivers 12.29 TFLOPS. That is a 38.6% higher FP32 rate for NVIDIA. For FP16, NVIDIA achieves 17.03 TFLOPS with a 1:1 ratio, while Intel reaches 24.58 TFLOPS with a 2:1 ratio, meaning Intel's FP16 peak is higher but only with reduced precision.

The NVIDIA card also has more shading units, 4352 versus 2560 for Intel, and more RT cores, 34 versus 20. Intel counters with more texture mapping units (160 versus 136) and more raster operation units (80 versus 48). The pixel rate for Intel is 192.0 GPixel/s versus 93.94 GPixel/s for NVIDIA, and the texture rate is 384.0 GTexel/s versus 266.2 GTexel/s. These numbers suggest Intel's architecture is tuned for fill-rate heavy workloads, while NVIDIA's is tuned for general compute and ray tracing.

Specification Differences

The two cards differ across nearly every major specification field. The Intel Arc Pro B65 uses the BMG-G21 chip with Xe2-HPG architecture, while the NVIDIA RTX PRO 2000 Blackwell uses the GB206 chip with Blackwell 2.0 architecture. The Intel card has 19,600 million transistors on a 272 mm² die, while NVIDIA has 21,900 million transistors on a 181 mm² die. This yields a transistor density of 72.1M per mm² for Intel and 121.0M per mm² for NVIDIA.

Clock speeds are dramatically different. The Intel card runs at a constant 2400 MHz for base and boost. The NVIDIA card has a base clock of 982 MHz and a boost clock of 1957 MHz. Memory clocks differ as well: Intel runs at 2375 MHz (19 Gbps effective) and NVIDIA at 1125 MHz (18 Gbps effective).

Memory configuration is a major split. Intel offers 32 GB of GDDR6 on a 256 bit bus, while NVIDIA offers 16 GB of GDDR7 on a 128 bit bus. Bandwidth is 608.0 GB/s for Intel versus 288.0 GB/s for NVIDIA. The compute units also differ: Intel has 2560 shading units, 160 TMUs, 80 ROPs, and 20 RT cores. NVIDIA has 4352 shading units, 136 TMUs, 48 ROPs, and 34 RT cores. NVIDIA also has 136 tensor cores, while Intel lists none.

Power and physical specifications differ sharply. Intel has a 200 W TDP, requires a 1x 8-pin connector, and suggests a 550 W power supply. NVIDIA has a 70 W TDP, requires no external connector, and suggests a 250 W power supply. Both are dual-slot cards, but NVIDIA lists dimensions of 167 mm length, 69 mm height, and 20 mm width, while Intel lists none. Display outputs also differ: Intel has 4x DisplayPort 2.1, while NVIDIA has 4x mini-DisplayPort 2.1b.

Architecture Differences

The Intel Arc Pro B65 is built on the Xe2-HPG architecture, specifically the Battlemage Pro Series generation. It uses a 5 nm process from TSMC with the BMG-G21 chip. The NVIDIA RTX PRO 2000 Blackwell uses the Blackwell 2.0 architecture, part of the Blackwell PRO W (x000) generation, also on a 5 nm TSMC process with the GB206 chip. Both are active production parts, but NVIDIA's release date is earlier at 2025-08-10, while Intel's is 2026-03-31.

The transistor count is close, with NVIDIA at 21,900 million and Intel at 19,600 million, but the die size difference is substantial. NVIDIA packs its transistors into 181 mm², while Intel uses 272 mm². This results in a much higher transistor density for NVIDIA at 121.0M per mm² versus 72.1M per mm² for Intel. The architectural focus also differs: NVIDIA includes 136 tensor cores for AI acceleration, while Intel lists none. NVIDIA's FP16 performance is identical to its FP32 at 17.03 TFLOPS (1:1 ratio), while Intel's FP16 is 24.58 TFLOPS with a 2:1 ratio, indicating a different precision handling approach.

The NVIDIA card also has a predecessor listed as Workstation Ada, while Intel has no predecessor in the database. Both cards support the same API set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

The data indicates two distinct market positions. The NVIDIA RTX PRO 2000 Blackwell is the higher-performing card according to benchmark percentiles, sitting at the 70th percentile with an average score of 25269. Its nearest rivals, including the AMD Radeon RX 6700M and GeForce RTX 3080 Ti Mobile, are within 1.8% of its score, showing competitive placement. The card's 17.03 TFLOPS FP32 and 136 tensor cores make it the choice for compute-heavy professional tasks, and its 70 W TDP with no external power connector allows for deployment in power-constrained systems.

The Intel Arc Pro B65, at the 50th percentile with no recorded benchmarks, relies on its specification advantages. Its 32 GB memory capacity and 608.0 GB/s bandwidth are unmatched by the NVIDIA card, making it the stronger candidate for memory-bound workloads such as large dataset manipulation or high-resolution texture work. The higher pixel rate of 192.0 GPixel/s and texture rate of 384.0 GTexel/s also favor fill-rate intensive rendering.

The choice depends on the workload profile. For general compute, ray tracing, and AI acceleration, the NVIDIA card's higher FP32 throughput, tensor cores, and better benchmark standing make it the logical pick. For memory capacity and bandwidth, the Intel card offers double the VRAM and more than double the bandwidth, which is decisive for certain professional applications. The power envelope is also a differentiator: NVIDIA's 70 W TDP is a fraction of Intel's 200 W TDP, enabling quieter, cooler, and more flexible system integration. The recorded data supports the NVIDIA card as the more broadly capable performer, while the Intel card is a specialist for memory-heavy scenarios.
