Architecture Differences

The Intel Arc Pro B390 and the NVIDIA RTX 4500 Ada Generation represent fundamentally different design philosophies. The Intel part is an integrated graphics processor (IGP) based on the Panther Lake chip, using the Xe3-LPG architecture. It belongs to the Arc Graphics-WM (Panther Lake) generation and was released on 2026-01-26. The NVIDIA part is a discrete workstation card using the AD103 chip with Ada Lovelace architecture, released on 2023-08-08.

The manufacturing processes differ significantly. Intel uses a 3 nm node fabricated in-house, while NVIDIA relies on TSMC's 5 nm process. The RTX 4500 Ada Generation carries 45,900 million transistors on a 379 mm² die, yielding a transistor density of 121.1M per mm². The Intel chip's transistor count and die size are not recorded in the database.

The compute resources diverge sharply. The RTX 4500 Ada Generation fields 7,680 shading units, 240 TMUs, and 80 ROPs. It also includes 60 ray tracing cores and 240 tensor cores. The Intel Arc Pro B390 has 1,536 shading units, 48 TMUs, and 24 ROPs, with 12 ray tracing cores and no tensor core count listed.

Clock behavior also differs. The Intel IGP runs at a 300 MHz base clock with a 2500 MHz boost. The NVIDIA card has a 2070 MHz base clock and a 2580 MHz boost. The Intel part's memory clock is system shared, while the NVIDIA card runs its GDDR6 memory at 2250 MHz with 18 Gbps effective speed.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The form factors are entirely different: the Intel part is an IGP with no slot width, while the NVIDIA card is dual-slot with dimensions of 245 mm length and 112 mm height. The Intel card uses no power connectors and has an 80 W TDP, while the NVIDIA card also uses no power connectors but has a 210 W TDP and lists a suggested PSU of 550 W.

Head-to-Head Benchmarks

The recorded benchmark data shows a clear performance gap, though the comparison is limited by the fact that the Intel Arc Pro B390 has no benchmark entries in the database. The NVIDIA RTX 4500 Ada Generation has two recorded tests. In Geekbench OpenCL, it scores 160,786. In Geekbench Vulkan, it scores 171,401. Its average benchmark score across these tests is 166,094.

The Intel Arc Pro B390 has an average benchmark score of 0 with no individual test entries, placing it at the 50th percentile among all GPUs. The RTX 4500 Ada Generation's 97th percentile ranking places it among the top tier of all recorded GPUs.

The nearest rivals to the RTX 4500 Ada Generation provide context for its positioning. The NVIDIA RTX A5500 scores 165,217, which is 0.5% behind the RTX 4500. The AMD Radeon PRO W7800 scores 164,894, 0.7% behind. The AMD Radeon Pro W6900X scores 168,574, which puts it 1.5% ahead of the RTX 4500. The NVIDIA A100 PCIe 40 GB scores 162,504, 2.2% behind.

In raw compute throughput, the RTX 4500 Ada Generation delivers 39.63 TFLOPS of FP32 performance and the same 39.63 TFLOPS of FP16 performance at a 1:1 ratio. The Intel Arc Pro B390 delivers 7.680 TFLOPS of FP32 and 15.36 TFLOPS of FP16 at a 2:1 ratio. The NVIDIA card is approximately 5.2 times faster in FP32 throughput.

Pixel and texture rates follow the same pattern. The RTX 4500 achieves 206.4 GPixel/s and 619.2 GTexel/s. The Intel part achieves 60.00 GPixel/s and 120.0 GTexel/s. The NVIDIA card is roughly 3.4 times faster in pixel fill rate and approximately 5.2 times faster in texture fill rate.

Memory bandwidth shows the largest relative difference. The RTX 4500 Ada Generation provides 432.0 GB/s of dedicated bandwidth from its 24 GB GDDR6 frame buffer. The Intel Arc Pro B390 depends on system shared memory with bandwidth listed as system dependent, meaning its effective memory performance cannot be quantified against the NVIDIA card from the recorded data.

The Verdict

The recorded data indicates the NVIDIA RTX 4500 Ada Generation is the substantially more capable workstation GPU. Its 97th percentile ranking versus the Intel Arc Pro B390's 50th percentile ranking places them in entirely different performance tiers. The NVIDIA card's average benchmark score of 166,094 demonstrates real-world measured performance, while the Intel part shows no recorded benchmark entries.

The RTX 4500 Ada Generation's 39.63 TFLOPS FP32 throughput is roughly five times the Intel part's 7.680 TFLOPS. Its 24 GB of dedicated GDDR6 memory with 432.0 GB/s bandwidth provides predictable, high-throughput memory access, whereas the Intel IGP relies on system memory with variable performance. The NVIDIA card also includes 240 tensor cores, which the Intel part lacks entirely.

The Intel Arc Pro B390's advantages are limited to its 80 W TDP, its integrated form factor that requires no power connectors, and its newer 3 nm process. These characteristics make it suitable for compact, low-power systems where the IGP is the only graphics option. The NVIDIA card's 210 W TDP and dual-slot form factor require a larger chassis and a 550 W suggested PSU.

For anyone selecting between these two, the decision is straightforward from the data. The NVIDIA RTX 4500 Ada Generation is the choice for workloads requiring maximum compute throughput, dedicated memory, and tensor core acceleration. The Intel Arc Pro B390 serves systems that need integrated graphics with modest performance and minimal power draw.

The benchmark data does not provide any recorded tests for the Intel Arc Pro B390, so its actual application performance cannot be compared directly. The RTX 4500 Ada Generation's nearest rivals, all within 2.2% of its average score, confirm it occupies a competitive position in the workstation segment. The Intel part's role is defined by its integration and low power envelope rather than by measured graphics performance.
