Intel Arc B770 vs NVIDIA RTX PRO 4500 Blackwell Server Comparison

Intel Arc B770 and NVIDIA RTX PRO 4500 Blackwell Server represent two distinct approaches to GPU design, one aimed at consumer desktop workloads and the other at server deployment. The database shows a stark contrast in their architectural priorities, memory configurations, and raw compute capabilities. This analysis draws exclusively from recorded specifications and benchmark data to outline where each card stands relative to the other.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark scores for these two GPUs. Both entries show an average benchmark score of zero and an empty list of nearest rivals, meaning there are no measured performance deltas to compare. The percentiles for both cards sit at 50, indicating they fall in the middle of the database's recorded GPU distribution, but without scores, this is purely a positional marker rather than a performance verdict.

Instead, the comparison must rely on the theoretical peak rates derived from their clock speeds and core configurations. The NVIDIA RTX PRO 4500 Blackwell Server delivers 50.70 TFLOPS of FP32 compute, which is 2.58 times the 19.66 TFLOPS offered by the Intel Arc B770. In FP16 workloads, the NVIDIA card holds a 1:1 ratio at 50.70 TFLOPS, while the Intel card reaches 39.32 TFLOPS using a 2:1 ratio. The NVIDIA card leads by 11.38 TFLOPS in FP16, or approximately 29% higher throughput.

Texture processing favors the NVIDIA card as well. The RTX PRO 4500 delivers 792.1 GTexel/s compared to 614.4 GTexel/s on the Arc B770, a difference of 177.7 GTexel/s. Pixel fill rates tell a different story: the Intel card reaches 307.2 GPixel/s, while the NVIDIA card reaches 270.5 GPixel/s. The Intel Arc B770 holds a 36.7 GPixel/s advantage in pixel throughput, roughly 13.6% higher than the NVIDIA part.

Memory bandwidth shows a clear NVIDIA lead. The RTX PRO 4500 uses 32 GB of GDDR7 across a 256-bit bus, achieving 800.3 GB/s. The Arc B770 uses 16 GB of GDDR6 across the same 256-bit bus width, achieving 512.0 GB/s. The NVIDIA card provides 288.3 GB/s more bandwidth, a 56.3% advantage. Memory capacity doubles on the NVIDIA side: 32 GB versus 16 GB.

The Intel Arc B770 operates at a higher base clock of 2100 MHz versus 1215 MHz on the NVIDIA card. Boost clocks are nearly identical, with the Intel card at 2400 MHz and the NVIDIA card at 2415 MHz, a 15 MHz difference. The NVIDIA card compensates for its lower base clock with substantially more execution resources: 10496 shading units versus 4096, 328 TMUs versus 256, and 82 RT cores versus 32. The Intel card has more ROPs at 128 versus 112.

The Verdict

The data indicates the NVIDIA RTX PRO 4500 Blackwell Server is the stronger compute performer by a wide margin in FP32, FP16, texture rate, memory bandwidth, and memory capacity. The Intel Arc B770 wins in pixel fill rate and operates with higher base clocks, but those advantages do not offset the NVIDIA card's 2.58x FP32 throughput lead.

The RTX PRO 4500 also carries more specialized hardware. Its 328 tensor cores have no equivalent field in the Intel specification, and its 82 RT cores more than double the Arc B770's 32. The NVIDIA card's transistor count of 45,600 million on a 378 mm² die yields a density of 120.6 million transistors per mm². The Intel card's transistor count is recorded as unknown on a slightly smaller 368 mm² die.

Power consumption flips the expected relationship. The NVIDIA card requests a 165 W TDP and a 450 W suggested PSU, while the Intel card requests 225 W TDP and a 550 W suggested PSU. The NVIDIA card delivers higher performance with a 60 W lower TDP, indicating better performance per watt in the recorded specifications.

Where Each One Wins

The NVIDIA RTX PRO 4500 Blackwell Server wins in compute-heavy scenarios. Its FP32 throughput of 50.70 TFLOPS suits general compute, simulation, and rendering tasks that rely on raw shader performance. The FP16 1:1 ratio at 50.70 TFLOPS supports workloads where half-precision arithmetic is used without a throughput penalty. The 32 GB GDDR7 memory with 800.3 GB/s bandwidth supports large datasets and memory-intensive operations. The 328 tensor cores provide dedicated matrix math acceleration, a feature absent from the Intel specification. The 82 RT cores give it a substantial advantage in ray-traced workloads. Its PCIe 5.0 x16 interface doubles the bus bandwidth of the Intel card's PCIe 4.0 x16 connection, and its single-slot form factor with no display outputs suits server density requirements.

The Intel Arc B770 wins in pixel fill rate at 307.2 GPixel/s, which benefits rasterization-heavy rendering at high resolutions. Its higher base clock of 2100 MHz suggests consistent performance under sustained loads. The card includes display outputs with 1x HDMI 2.1a and 3x DisplayPort 2.1, making it suitable for direct display connection. Its 225 W TDP is higher than the NVIDIA part, but the dual-slot cooler and 6-pin plus 8-pin power connectors indicate a conventional desktop installation profile. The 16 GB GDDR6 memory is half the NVIDIA capacity, but the 512.0 GB/s bandwidth remains sufficient for many desktop workloads.
