Intel Arc B770 vs NVIDIA RTX PRO 4500 Blackwell Workstation Comparison

Head-to-Head Benchmarks

The recorded data shows no direct benchmark scores for either the Intel Arc B770 or the NVIDIA RTX PRO 4500 Blackwell Workstation. Both GPUs hold a 50th percentile ranking among all GPUs in the database, with an average benchmark score of zero. This indicates that while both cards are positioned in the mid-tier of the overall performance distribution, no head-to-head measurements have been captured to establish a comparative performance delta. The absence of benchmark data means that any performance advantage must be inferred from the architectural specifications and feature sets recorded in the database.

Without direct measurement scores, the database relies on theoretical throughput figures to differentiate the two. The NVIDIA RTX PRO 4500 delivers 50.53 TFLOPS of FP32 compute, which is substantially higher than the Intel Arc B770's 19.66 TFLOPS. This represents a 2.57x advantage in raw floating-point throughput for the NVIDIA card. In FP16 workloads, the NVIDIA card maintains 50.53 TFLOPS with a 1:1 ratio, while the Intel card reaches 39.32 TFLOPS using a 2:1 ratio. The NVIDIA card also leads in texture throughput, with 789.5 GTexel/s versus 614.4 GTexel/s for Intel, a 28.5% advantage. However, the Intel card counters in pixel throughput, delivering 307.2 GPixel/s compared to 269.6 GPixel/s for NVIDIA, a 14% lead in fill-rate-oriented tasks.

Memory bandwidth further separates the two. The NVIDIA card uses 32 GB of GDDR7 memory across a 256-bit bus to achieve 896.0 GB/s, while the Intel card uses 16 GB of GDDR6 across the same 256-bit bus for 512.0 GB/s. The NVIDIA card thus provides 1.75x the memory bandwidth and double the capacity. These figures suggest that the NVIDIA card is positioned for compute-heavy and memory-intensive workloads, while the Intel card offers competitive pixel throughput at a lower compute ceiling.

Architecture Differences

The two GPUs come from different architectural generations and design philosophies. The Intel Arc B770 is built on the Xe2-HPG architecture, part of the Battlemage (Arc 7) generation, using the BMG-G31 chip. It is manufactured on a 5 nm process at TSMC, with a die size of 368 mm². The transistor count is listed as unknown, and no transistor density figure is recorded. The predecessor to this card is listed as Alchemist, and its release date is recorded as 2025-12-31.

The NVIDIA RTX PRO 4500 Blackwell Workstation uses the Blackwell 2.0 architecture, part of the Blackwell PRO W (x000) generation, built on the GB203 chip. It is also manufactured on a 5 nm process at TSMC, with a die size of 378 mm². The database records 45,600 million transistors, giving a transistor density of 120.6M per mm². Its predecessor is Workstation Ada, and it was released on 2025-03-17, with a production status of Active.

The core configurations differ markedly. The NVIDIA card has 10,496 shading units, 328 texture mapping units, 112 ROPs, 82 RT cores, and 328 tensor cores. The Intel card has 4,096 shading units, 256 TMUs, 128 ROPs, and 32 RT cores, with no tensor cores recorded. The NVIDIA card's shading unit count is 2.56x higher, and its RT core count is 2.56x higher as well. The Intel card has 14 more ROPs than the NVIDIA card, which explains its higher pixel rate.

Clock behavior also differs. The Intel card has a base clock of 2100 MHz and a boost clock of 2400 MHz, while the NVIDIA card has a base clock of 1635 MHz and a boost clock of 2407 MHz. The NVIDIA card's boost clock is slightly higher, but its base clock is 465 MHz lower. Memory clocks show the NVIDIA card operating at 1750 MHz with 28 Gbps effective, while the Intel card runs at 2000 MHz with 16 Gbps effective.

The NVIDIA card supports PCIe 5.0 x16, while the Intel card uses PCIe 4.0 x16. Display outputs differ as well: the Intel card has 1x HDMI 2.1a and 3x DisplayPort 2.1, while the NVIDIA card has 4x DisplayPort 2.1b. Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The Verdict

The data indicates that the NVIDIA RTX PRO 4500 Blackwell Workstation is the more compute-capable card across nearly every measured specification. Its FP32 throughput, FP16 throughput, texture rate, memory bandwidth, memory capacity, shading unit count, RT core count, and tensor core support all exceed those of the Intel Arc B770. The Intel card holds advantages in pixel rate, base clock, and ROP count. For workloads that rely on pixel fill-rate, such as certain rasterization tasks, the Intel card may hold a narrow edge. For any workload that stresses compute throughput, ray tracing, tensor operations, or memory bandwidth, the NVIDIA card is the clear choice based on the recorded data.

The NVIDIA card also offers a larger memory pool at 32 GB, which is critical for large datasets or high-resolution textures. Its GDDR7 memory provides 1.75x the bandwidth of the Intel card's GDDR6. The NVIDIA card includes tensor cores, which the Intel card lacks entirely, making the NVIDIA card the only option for AI or machine learning inference tasks. The Intel card's lack of tensor cores is a significant limitation in the recorded specifications.

The power draw figures are close but not equal: the NVIDIA card has a TDP of 200 W, while the Intel card has a TDP of 225 W. Both require a 550 W suggested PSU. The NVIDIA card uses a single 16-pin power connector, while the Intel card uses 1x 6-pin and 1x 8-pin connectors. The NVIDIA card is physically smaller, with a length of 267 mm (10.5 inches), a height of 111 mm (4.4 inches), and a width of 40 mm (1.6 inches), while the Intel card's dimensions are not recorded. Both are dual-slot cards.
