The RTX 5090 is a discrete add-in board using the GB202 chip with Blackwell 2.0 architecture, built on TSMC's 5 nm process. The RTX 5090's die measures 750 mm² and contains 92,200 million transistors with a transistor density of 122.9M per mm².

The compute resources differ dramatically. The Intel part has 1,536 shading units, 48 texture mapping units, 24 ROPs, and 12 ray tracing cores. The RTX 5090 has 21,760 shading units, 680 TMUs, 176 ROPs, and 170 RT cores. The NVIDIA card also includes 680 tensor cores, a feature absent from the Intel part's specifications. The Intel GPU's FP16 throughput is 15.36 TFLOPS at a 2:1 ratio, while the RTX 5090 achieves 104.8 TFLOPS at a 1:1 ratio.

Pixel and texture rates follow the same pattern. The Intel Arc G3 Extreme reaches 60.00 GPixel/s and 120.0 GTexel/s. The RTX 5090 reaches 423.6 GPixel/s and 1,636.8 GTexel/s. Clock behavior also differs: the Intel chip runs at a 300 MHz base and 2500 MHz boost, while the RTX 5090 has a higher 2017 MHz base but a lower 2407 MHz boost. The RTX 5090's memory clock is listed at 1750 MHz with 28 Gbps effective data rate.

Physical and interface differences are pronounced. The Intel part uses an IGP bus interface with no slot width, no power connectors, and display outputs described as portable device dependent. The RTX 5090 uses PCIe 5.0 x16, occupies a dual-slot form factor, measures 304 mm in length, 137 mm in height, and 40 mm in width. Its display outputs include 1x HDMI 2.1b and 3x DisplayPort 2.1b. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 5090 lists a predecessor of GeForce 40 and a successor of GeForce 60, while the Intel part has no listed predecessor or successor.

Head-to-Head Benchmarks

The database records benchmarks only for the RTX 5090; the Intel Arc G3 Extreme has no recorded benchmark scores. The RTX 5090's average benchmark score is 79,842, placing it at the 92nd percentile among all GPUs. Its nearest rivals cluster tightly around it: the NVIDIA Tesla P100 PCIe 16 GB scores 79,605, which is 0.3% behind; the Tesla P100 PCIe 12 GB scores 79,396, 0.6% behind; the AMD Radeon RX 6850M XT scores 78,940, 1.1% behind; and the AMD Radeon Pro Vega 64X scores 80,959, which is 1.4% ahead.

The RTX 5090's individual benchmark results show strong performance across different APIs. In 3DMark Steel Nomad DX12, it scores 18,355. Geekbench OpenCL yields 334,370, and Geekbench Vulkan yields 376,728. PassMark results include 226 for DirectX 10, 341 for DirectX 11, 185 for DirectX 12, 395 for DirectX 9, 1,413 for G2D, 39,650 for G3D, and 26,756 for GPU compute.

The Intel Arc G3 Extreme sits at the 50th percentile among all GPUs with an average benchmark score of 0 and no nearest rivals listed. Its FP32 throughput of 7.680 TFLOPS compares to the RTX 5090's 104.8 TFLOPS, meaning the RTX 5090 delivers roughly 13.6 times the raw floating-point throughput. The RTX 5090's texture rate of 1,636.8 GTexel/s is about 13.6 times the Intel part's 120.0 GTexel/s, and its pixel rate of 423.6 GPixel/s is about 7 times the Intel part's 60.00 GPixel/s.

The Verdict

The recorded data indicates a decisive performance gap. The RTX 5090 occupies the 92nd percentile of all GPUs, while the Intel Arc G3 Extreme sits at the 50th percentile. The RTX 5090 has an average benchmark score of 79,842; the Intel part has no recorded score. The RTX 5090's FP32 output of 104.8 TFLOPS dwarfs the Intel part's 7.680 TFLOPS.

The use cases diverge clearly. The RTX 5090 is designed for high-end discrete graphics workloads requiring 32 GB of dedicated GDDR7 memory, 1.79 TB/s of bandwidth, and a 575 W power envelope. The Intel Arc G3 Extreme is an integrated part with an 80 W TDP, system shared memory, and no power connectors, suited for portable devices where the system provides the memory and display path. The RTX 5090's 170 RT cores and 680 tensor cores position it for ray tracing and AI-accelerated workloads, while the Intel part's 12 RT cores and no tensor core count indicate a more modest feature set.

The RTX 5090 launched at 1,999 USD in January 2025. The Intel Arc G3 Extreme has no launch MSRP in the database and releases in May 2026. Buyers seeking maximum compute, memory bandwidth, and API-level performance should select the RTX 5090 based on its benchmark dominance. Systems requiring an integrated graphics solution with minimal power draw and no add-in card footprint would use the Intel part, though its performance class is far below the NVIDIA flagship.

The RTX 5090 also has dedicated 32 GB GDDR7 memory with 1.79 TB/s bandwidth, while the Intel part depends entirely on system shared memory. The NVIDIA card includes 170 RT cores and 680 tensor cores, compared to 12 RT cores and no tensor cores on the Intel part. The RTX 5090's 92nd percentile ranking and average benchmark score of 79,842 confirm its position at the top of the database.

The Intel Arc G3 Extreme wins on power efficiency and integration. Its 80 W TDP is dramatically lower than the RTX 5090's 575 W. It requires no power connectors, no suggested PSU rating, and uses an IGP bus interface, making it suitable for compact portable devices. Its display outputs are portable device dependent, meaning the host device controls connectivity. The Intel part's 3 nm process from Intel Foundry contrasts with the RTX 5090's 5 nm process from TSMC, though the Intel chip's transistor count and die size are unknown in the database.

The RTX 5090's nearest rivals in the database are all within 1.4% of its average score, indicating a competitive field at the top. The Intel Arc G3 Extreme has no nearest rivals listed, reflecting its unique position as an integrated part. The RTX 5090's benchmark results span multiple APIs: 18,355 in 3DMark Steel Nomad DX12, 334,370 in Geekbench OpenCL, 376,728 in Geekbench Vulkan, and 39,650 in PassMark G3D. These measurements give the RTX 5090 a clear advantage for demanding graphics workloads. The Intel Arc G3 Extreme, with no recorded benchmark scores and a 50th percentile ranking, serves a fundamentally different role in the product landscape.
