Intel Arc Pro B390 vs NVIDIA RTX PRO 4500 Blackwell Comparison

Head-to-Head Benchmarks

The recorded data shows no direct head-to-head benchmark runs between the Intel Arc Pro B390 and the NVIDIA RTX PRO 4500 Blackwell. The database contains benchmark scores only for the NVIDIA part, leaving the Intel side with an empty benchmark profile. This asymmetry limits direct numerical comparisons, but the available figures for the RTX PRO 4500 provide a reference point for interpreting its standing.

The RTX PRO 4500 Blackwell posts an average benchmark score of 31532 across all recorded tests. Its percentile ranking against all GPUs in the database sits at 76, indicating that it outperforms roughly three-quarters of the tracked graphics hardware. In 3DMark Steel Nomad DX12, the card records a score of 7025, a result that reflects strong rasterization performance under a modern DirectX 12 workload. Geekbench Vulkan shows 221768, which measures compute and graphics throughput in a cross-platform API context.

PassMark results for the RTX PRO 4500 reveal a varied profile across DirectX generations. The DirectX 9 test returns 397, the DirectX 10 test returns 204, the DirectX 11 test returns 320, and the DirectX 12 test returns 119. These numbers indicate that the card's highest legacy DirectX score comes from the older DirectX 9 path, while its lowest appears in DirectX 12. The PassMark G3D score of 33360 and the GPU compute score of 19255 further characterize the card's overall graphics and compute throughput. The G2D score of 1336 captures 2D acceleration performance, which is comparatively modest next to the 3D results.

The nearest rivals in the database for the RTX PRO 4500 are clustered tightly around its average score. The NVIDIA TITAN RTX holds an average score of 31676, which is 0.5% lower than the RTX PRO 4500's average. The NVIDIA GRID M60-1Q and NVIDIA Quadro M5000 each show an average score of 31220 and 31206 respectively, both landing 1% above the RTX PRO 4500. The Intel Arc Pro A30M records an average score of 31894, which is 1.1% below the RTX PRO 4500. This narrow spread, with deltas ranging from -1.1% to +1%, suggests that the RTX PRO 4500 occupies a performance band where several older or differently targeted products converge.

Without any recorded benchmarks for the Intel Arc Pro B390, the data cannot confirm a single win for either side in a head-to-head sense. The wins tally stands at zero for both parts. The implication is not that the Intel product lacks capability, but that the database has no measured results to place against the NVIDIA card's extensive benchmark suite.

The Verdict

The data supports a clear choice for users who prioritize measured performance: the NVIDIA RTX PRO 4500 Blackwell is the only one of the two with verified benchmark results, and those results place it in the 76th percentile of all GPUs. Its average score of 31532 and its proximity to rivals like the TITAN RTX and Quadro M5000 confirm that it delivers substantial graphics throughput across multiple APIs. The Intel Arc Pro B390 has no recorded benchmark scores, no average score, and no percentile ranking beyond a neutral 50th percentile placeholder, which reflects an absence of data rather than a measured position.

For a workstation or professional visualization context, the RTX PRO 4500 brings 32 GB of GDDR7 memory, a 256-bit bus, and 896.0 GB/s of bandwidth, all of which are concrete specifications that support large datasets and high-resolution rendering. The Intel part relies on system shared memory, making its bandwidth system dependent and its memory behavior variable across platforms. Users who need predictable, high-capacity local memory should look to the NVIDIA card based on the recorded specifications alone.

The Intel Arc Pro B390 does have structural advantages in power and integration. Its 80 W TDP and IGP form factor mean it can operate within a mobile or compact platform without a dedicated power connector. The RTX PRO 4500 requires a 200 W TDP, a dual-slot cooler, a 16-pin power connector, and a suggested 550 W power supply. For a system builder constrained by chassis space or thermal limits, the Intel part is the only option that fits an integrated design. The data does not show how the Intel GPU performs, so that choice rests on form factor and power considerations rather than measured speed.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. The Intel Arc Pro B390 uses the Panther Lake chip with the Xe3-LPG architecture, built on a 3 nm process at Intel. The NVIDIA RTX PRO 4500 Blackwell uses the GB203 chip with the Blackwell 2.0 architecture, built on a 5 nm process at TSMC. The process node difference gives Intel a density advantage on paper, though the database does not list transistor counts or die size for the Intel chip. NVIDIA discloses 45,600 million transistors on a 378 mm² die, yielding a transistor density of 120.6 million per square millimeter.

Core counts diverge sharply. The Intel part has 1536 shading units, 48 texture mapping units, 24 ROPs, and 12 ray tracing cores. The NVIDIA part has 10496 shading units, 328 TMUs, 112 ROPs, and 82 ray tracing cores. NVIDIA also includes 328 tensor cores, while the Intel specification lists no tensor core count. These differences translate directly into raw throughput figures: the Intel GPU delivers 7.680 TFLOPS of FP32 and 15.36 TFLOPS of FP16 at a 2:1 ratio. The NVIDIA GPU delivers 50.53 TFLOPS of FP32 and 50.53 TFLOPS of FP16 at a 1:1 ratio, meaning it does not halve FP16 throughput relative to FP32.

Clock behavior also differs. The Intel chip runs at a 300 MHz base clock and a 2500 MHz boost clock. The NVIDIA chip starts at 1635 MHz base and boosts to 2407 MHz. Despite a lower boost clock, the NVIDIA part achieves far higher pixel and texture rates: 269.6 GPixel/s and 789.5 GTexel/s versus 60.00 GPixel/s and 120.0 GTexel/s for Intel. The NVIDIA memory clock is listed at 1750 MHz with 28 Gbps effective speed, while the Intel memory clock is system shared.

API support matches between the two: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA card outputs to 4x DisplayPort 2.1b, whereas the Intel card's display outputs are portable device dependent. The bus interface also separates them: NVIDIA uses PCIe 5.0 x16, while Intel uses an integrated graphics processor interface with no external bus.

Where Each One Wins

Based strictly on recorded data, the NVIDIA RTX PRO 4500 Blackwell wins in every measurable performance category. Its FP32 throughput of 50.53 TFLOPS dwarfs the Intel part's 7.680 TFLOPS. Its pixel rate of 269.6 GPixel/s and texture rate of 789.5 GTexel/s far exceed the Intel figures of 60.00 GPixel/s and 120.0 GTexel/s. The NVIDIA card's 32 GB of dedicated GDDR7 memory with 896.0 GB/s bandwidth provides a clear advantage for workloads that require large working sets, such as GPU compute, rendering, or data processing. Its 76th percentile ranking and average score of 31532 give it a measurable standing that the Intel part cannot match, since the Intel GPU has no recorded benchmarks.

The Intel Arc Pro B390 wins on integration and power draw. Its 80 W TDP is less than half of the NVIDIA card's 200 W TDP. It requires no power connector and fits an IGP slot width, meaning it can be embedded into a portable device or compact system without dedicated graphics power delivery. Its 300 MHz base clock and 2500 MHz boost clock show a wide dynamic range, which suits power-constrained environments where burst performance matters. The Intel part also uses a 3 nm process, which suggests a newer manufacturing generation than the NVIDIA card's 5 nm process, even though the database does not provide transistor or die size data for Intel.

For legacy DirectX workloads, the NVIDIA card's PassMark results show its strongest legacy score in DirectX 9 at 397, while DirectX 12 returns only 119. This pattern suggests that the RTX PRO 4500 may not be optimized for older API paths, but the database does not provide comparable Intel results. The Intel part's API list matches NVIDIA's, so both support the same DirectX, OpenGL, and Vulkan versions.

Specification Differences

The two GPUs differ across nearly every recorded specification. The Intel Arc Pro B390 uses the Panther Lake chip with Xe3-LPG architecture on a 3 nm Intel process. The NVIDIA RTX PRO 4500 Blackwell uses the GB203 chip with Blackwell 2.0 architecture on a 5 nm TSMC process. Intel does not list transistor count or die size; NVIDIA lists 45,600 million transistors on a 378 mm² die with a density of 120.6 million per square millimeter.

Clock speeds differ substantially. Intel runs at 300 MHz base and 2500 MHz boost. NVIDIA runs at 1635 MHz base and 2407 MHz boost. Memory clocks also diverge: Intel uses system shared memory, while NVIDIA uses 1750 MHz with 28 Gbps effective speed. Memory size, type, bus width, and bandwidth all differ, with NVIDIA offering 32 GB GDDR7 on a 256-bit bus at 896.0 GB/s, and Intel offering system shared memory with system dependent bandwidth.

Core configurations show Intel with 1536 shading units, 48 TMUs, 24 ROPs, and 12 RT cores. NVIDIA has 10496 shading units, 328 TMUs, 112 ROPs, and 82 RT cores.
