Intel Arc Pro B65 vs NVIDIA RTX PRO 5000 Blackwell Comparison

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark runs between the Intel Arc Pro B65 and the NVIDIA RTX PRO 5000 Blackwell. Consequently, the comparison rests on the measured performance of the NVIDIA card and the architectural and specification records for both. The Intel Arc Pro B65 carries an average benchmark score of zero with no individual test entries, while the RTX PRO 5000 Blackwell delivers a substantial average score of 182,109 across three recorded tests.

The NVIDIA card posts a 98th percentile ranking among all GPUs in the database. Its nearest rivals provide context: the NVIDIA A100 SXM4 80 GB scores 183,725, which is 0.9% higher, and the NVIDIA RTX 5000 Ada Generation scores 184,664, 1.4% higher. The GeForce RTX 4090 D trails by 2.3% with a score of 178,050, and the A100 SXM4 40 GB sits 2.7% above at 187,147. These deltas indicate that the RTX PRO 5000 Blackwell operates in the upper tier of professional workstation graphics, effectively matching its closest competitors within a narrow band of roughly 3%.

In the recorded tests, the RTX PRO 5000 Blackwell achieves 9,579.5 in 3DMark Steel Nomad DX12, 254,116 in Geekbench OpenCL, and 282,631 in Geekbench Vulkan. The OpenCL and Vulkan scores are particularly high, with Vulkan exceeding OpenCL by about 11%, a pattern that suggests strong compute throughput across different API workloads. The 3DMark result, while lower in absolute terms, reflects the demanding nature of that specific ray-traced and rasterized workload.

For the Intel Arc Pro B65, the absence of benchmark entries means no quantitative wins can be credited from direct measurements. However, the specification data allows for a theoretical positioning. The Intel card lists 2560 shading units, 160 texture mapping units, and 80 raster output units, with a peak FP32 rate of 12.29 TFLOPS. The NVIDIA card lists 14,080 shading units, 440 TMUs, and 160 ROPs, with FP32 at 66.94 TFLOPS. That places the NVIDIA part at roughly 5.4 times the raw FP32 throughput of the Intel part. The Intel card's pixel rate is 192.0 GPixel/s versus 380.3 GPixel/s for NVIDIA, and its texture rate is 384.0 GTexel/s versus 1,045.9 GTexel/s.

Memory bandwidth follows a similar pattern. The RTX PRO 5000 Blackwell uses 48 GB of GDDR7 on a 384-bit bus, delivering 1.34 TB/s. The Intel card uses 32 GB of GDDR6 on a 256-bit bus, delivering 608.0 GB/s. That is a 2.2 times bandwidth advantage for NVIDIA. Clock behavior also differs: Intel runs a flat 2400 MHz for both base and boost, while NVIDIA starts at 1740 MHz base and boosts to 2377 MHz.

The data shows a decisive performance gap in favor of the NVIDIA card across every measurable compute and memory metric. The Intel part does hold advantages in power efficiency per the recorded TDP figures, with 200 W versus 300 W, and a lower suggested power supply of 550 W versus 700 W. But in absolute performance, the NVIDIA card leads by a wide margin.

The Verdict

From the recorded data, the NVIDIA RTX PRO 5000 Blackwell is the clear performance leader. Its 98th percentile ranking, average benchmark score of 182,109, and 66.94 TFLOPS FP32 throughput place it in the top tier of workstation GPUs. The Intel Arc Pro B65, with no recorded benchmarks and a 50th percentile rank, cannot be positioned as a performance competitor based on the database.

The verdict for the NVIDIA card is straightforward: it is for professionals whose workloads demand maximum compute throughput, large memory capacity, and high bandwidth. The 48 GB GDDR7 frame buffer and 1.34 TB/s bandwidth support large models and high-resolution rendering. The 110 RT cores and 440 tensor cores indicate strong ray tracing and AI acceleration capabilities, though the database does not list benchmark scores for those features specifically.

The Intel Arc Pro B65 is a different proposition. Its 32 GB GDDR6 memory and 12.29 TFLOPS FP32 rate are modest by comparison. The 20 RT cores and absence of tensor cores in the record suggest a more limited feature set for AI and ray-traced workloads. Its 200 W TDP and 550 W suggested power supply make it a lower-power option, and it uses a single 8-pin connector versus the NVIDIA card's 16-pin connector.

For users who prioritize raw performance, the data points exclusively to the RTX PRO 5000 Blackwell. For users who need a capable workstation GPU with lower power demands, the Intel card offers a functional alternative, but the database provides no benchmark evidence to quantify its real-world performance. The percentile rankings, 98 versus 50, summarize the gap: the NVIDIA card sits near the top of the database, while the Intel card sits at the median.

Architecture Differences

The two GPUs use different architectures from different generations. The Intel Arc Pro B65 is built on Xe2-HPG, part of the Battlemage Pro Series, using the BMG-G21 chip. The NVIDIA RTX PRO 5000 Blackwell uses the Blackwell 2.0 architecture with the GB202 chip, belonging to the Blackwell PRO W generation.

Both are fabricated on a 5 nm process at TSMC, but the chip scales differ enormously. The Intel die measures 272 mm² and contains 19,600 million transistors, yielding a density of 72.1 million per mm². The NVIDIA die measures 750 mm² and contains 92,200 million transistors, yielding 122.9 million per mm². The NVIDIA chip is nearly three times larger in area and holds 4.7 times more transistors.

The transistor density difference indicates that NVIDIA packs logic more tightly. The Intel card has 2560 shading units, 160 TMUs, 80 ROPs, and 20 RT cores. The NVIDIA card has 14,080 shading units, 440 TMUs, 160 ROPs, 110 RT cores, and 440 tensor cores. The RTX PRO 5000 Blackwell also lists tensor cores, which the Intel card does not record at all.

Memory technology differs as well. Intel uses GDDR6 with a 256-bit bus, while NVIDIA uses GDDR7 with a 384-bit bus. The NVIDIA card's memory clock runs at 1750 MHz with 28 Gbps effective, while Intel runs at 2375 MHz with 19 Gbps effective. Despite the higher clock on Intel's memory, NVIDIA's wider bus and newer memory type produce far higher bandwidth.

The FP16 compute rates reveal another architectural difference. Intel lists FP16 at 24.58 TFLOPS with a 2:1 ratio to FP32, indicating dedicated half-precision throughput. NVIDIA lists FP16 at 66.94 TFLOPS with a 1:1 ratio, meaning its FP16 rate matches FP32 exactly, a design choice that emphasizes compute consistency across precision levels.

Both support the same API set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ in version: Intel provides four DisplayPort 2.1 outputs, while NVIDIA provides four DisplayPort 2.1b outputs. Both use PCIe 5.0 x16 interfaces.
