Intel Arc G3 vs NVIDIA GeForce RTX 5090 SE Comparison

The database pairs two active GPUs with opposite physical designs. The Intel Arc G3 is an IGP in the Panther Lake generation, using Xe3-LPG architecture on Intel's 3 nm process. The NVIDIA GeForce RTX 5090 SE is a dual-slot discrete card in the GeForce 50 series, using Blackwell 2.0 on a 5 nm process at TSMC. Both entries sit at the 50th percentile versus all GPUs and both have an average benchmark score of 0, which places the comparison on listed specifications rather than measured benchmark scores.

Architecture Differences

The two architectures target different integration levels. The Arc G3 belongs to the Arc Graphics-M (Panther Lake) generation and uses Xe3-LPG. The RTX 5090 SE belongs to the GeForce 50 generation and uses Blackwell 2.0 on the GB202 chip. The Intel part is manufactured on a 3 nm node at Intel; the NVIDIA part is manufactured on a 5 nm node at TSMC.

Transistor data is one-sided. The RTX 5090 SE contains 92,200 million transistors on a 750 mm² die, for a density of 122.9M / mm². The Arc G3's transistor count and die size are listed as unknown, so no density figure exists for it.

Core counts are heavily skewed. The Arc G3 has 1280 shading units, 40 TMUs, 20 ROPs, and 10 RT cores, with no tensor core count listed. The RTX 5090 SE has 14080 shading units, 440 TMUs, 160 ROPs, 110 RT cores, and 440 tensor cores. The NVIDIA part also carries a 384 bit GDDR7 memory interface with 24 GB and 1.34 TB/s, while the Intel part uses System Shared memory and System Dependent bandwidth.

Power and packaging reinforce the split. The Arc G3 is rated at 25 W, uses an IGP bus interface, needs no power connectors, and has display outputs that are portable device dependent. The RTX 5090 SE is rated at 500 W, uses a dual-slot form factor, requires one 16-pin connector, lists a 900 W suggested PSU, uses PCIe 5.0 x16, and provides 1x HDMI 2.1b and 3x DisplayPort 2.1b. The NVIDIA card is 267 mm long, 111 mm tall, and 40 mm wide; the Intel part has no listed dimensions.

Head-to-Head Benchmarks

The database records no head-to-head benchmark scores for this pair. The win counts are 0 for both sides. The available numerical comparison therefore comes from listed throughput rates and fixed-function counts.

Every listed throughput rate favors the RTX 5090 SE. Pixel rate is 380.3 GPixel/s against the Arc G3's 48.00 GPixel/s. Texture rate is 1,045.9 GTexel/s against 96.00 GTexel/s. FP32 compute is 66.94 TFLOPS against 6.144 TFLOPS. FP16 compute is 66.94 TFLOPS (1:1) against 12.29 TFLOPS (2:1). The Intel part's 2:1 FP16 ratio doubles its FP16 rate relative to its own FP32, but the NVIDIA part's absolute FP16 figure is still higher.

Fixed-function resources follow the same direction. The RTX 5090 SE has 110 RT cores, 440 tensor cores, 14080 shading units, 440 TMUs, and 160 ROPs, versus 10 RT cores, no listed tensor core count, 1280 shading units, 40 TMUs, and 20 ROPs for the Arc G3.

The Arc G3's largest recorded advantages are in power and integration. It draws 25 W, uses no power connectors, and fits an IGP slot width. The RTX 5090 SE draws 500 W, requires one 16-pin connector, and occupies a dual-slot form factor. The Intel part also has no listed dimensions, which is consistent with an IGP whose physical footprint is defined by the host device rather than a discrete board.

The Verdict

The recorded data defines two separate use profiles. The RTX 5090 SE is the high-throughput part: it leads in pixel rate, texture rate, FP32, FP16, memory capacity, memory bandwidth, shading units, TMUs, ROPs, RT cores, and tensor cores. The Arc G3 is the low-power integrated part: it leads in TDP, connector requirements, and slot width, and it depends on system memory rather than a dedicated 24 GB GDDR7 pool.

The absence of benchmark scores means the verdict is based on listed specifications. For workloads that scale with the recorded throughput and memory figures, the data points to the RTX 5090 SE. For platforms that require an IGP with a 25 W TDP and no power connectors, the data points to the Arc G3. The two are not direct substitutes; they occupy separate physical and electrical categories.
