Intel Arc G3 vs NVIDIA GeForce RTX 5090 Comparison

Head-to-Head Benchmarks

The Intel Arc G3 and NVIDIA GeForce RTX 5090 occupy opposite ends of the graphics spectrum, and the recorded data reflects a complete mismatch in compute capability. The RTX 5090 delivers a FP32 throughput of 104.8 TFLOPS, while the Arc G3 manages 6.144 TFLOPS. That difference is a factor of roughly 17x in raw shader output, a gap that appears consistently across every recorded metric.

The RTX 5090 also holds a massive advantage in memory bandwidth. The NVIDIA part uses 32 GB of GDDR7 across a 512-bit bus for 1.79 TB/s of bandwidth. The Arc G3 uses system shared memory, with bandwidth listed as system dependent. No fixed comparison is possible, but the architectural ceiling for the integrated part is far below a dedicated 1.79 TB/s path.

In texture and pixel throughput, the RTX 5090 outputs 1,636.8 GTexel/s and 423.6 GPixel/s. The Arc G3 outputs 96.00 GTexel/s and 48.00 GPixel/s. The RTX 5090 is about 17x faster in texturing and about 8.8x faster in pixel fill. These numbers indicate the discrete card handles high resolution and heavy effects with far more headroom.

The RTX 5090's recorded benchmark scores are extensive. Its 3DMark Steel Nomad DX12 score is 18,355. Geekbench OpenCL shows 334,370 and Vulkan shows 376,728. Passmark G3D is 39,650, with GPU compute at 26,756. The Arc G3 has no recorded benchmark scores in the database, leaving its percentile at 50 versus the RTX 5090's 92. The average benchmark score for the RTX 5090 is 79,842, with the nearest rival, the NVIDIA Tesla P100 PCIe 16 GB, at 79,605, a delta of 0.3 percent. The AMD Radeon RX 6850M XT trails by 1.1 percent, and the AMD Radeon Pro Vega 64X leads by 1.4 percent.

Clock speeds tell a similar story. The RTX 5090 runs a base of 2017 MHz and boosts to 2407 MHz. The Arc G3 runs a base of 300 MHz and boosts to 2400 MHz. The boost clocks are close, but the RTX 5090 sustains a much higher base frequency, which matters for consistent performance under load. The RTX 5090's 92,200 million transistors on a 750 mm² die compare against an unknown transistor count and die size for the Arc G3.

Where Each One Wins

The RTX 5090 wins every measurable category where the database has records. Its 21760 shading units, 680 TMUs, and 176 ROPs dwarf the Arc G3's 1280 shading units, 40 TMUs, and 20 ROPs. Ray tracing hardware follows the same pattern: 170 RT cores on the NVIDIA part versus 10 on the Intel part. Tensor cores on the RTX 5090 number 680, while the Arc G3 lists none.

The RTX 5090's wins are most pronounced in sustained, high-throughput workloads. The Passmark DX12 score of 185 and DX11 score of 341, combined with the 3DMark Steel Nomad result, indicate strong performance in modern DirectX 12 titles. The Geekbench Vulkan score of 376,728 shows the card handles compute-heavy Vulkan workloads well. The Passmark GPU compute score of 26,756 supports this, indicating strong general-purpose compute capability.

The Arc G3's only wins are in power efficiency and physical footprint. Its 25 W TDP versus 575 W for the RTX 5090 means the integrated part draws a fraction of the power. The Arc G3 is an IGP with no power connectors and a bus interface of IGP, whereas the RTX 5090 is a dual-slot card requiring a 16-pin connector and a 950 W suggested PSU. For a portable or low-power device, the Arc G3 is the only viable option. The RTX 5090 cannot function without a full desktop power delivery system.

The RTX 5090's release date of January 2025 predates the Arc G3's May 2026 release, but the NVIDIA card's benchmarks and specifications place it in a different performance class entirely. The Arc G3 is designed for integrated graphics duties, not competing with flagship discrete cards.

Specification Differences

The two cards differ in nearly every specification field. The RTX 5090 uses a GB202 chip on a 5 nm TSMC process, while the Arc G3 uses a Panther Lake chip on a 3 nm Intel process. The RTX 5090 has 92,200 million transistors on a 750 mm² die with a transistor density of 122.9M per mm². The Arc G3 has unknown transistor count and die size.

Memory is a major split: the RTX 5090 has 32 GB of GDDR7 with a 512-bit bus and 1.79 TB/s bandwidth, while the Arc G3 relies on system shared memory with system dependent bandwidth. The RTX 5090's memory clock is 1750 MHz at 28 Gbps effective, versus system shared for the Arc G3.

Compute units differ drastically. The RTX 5090 has 21760 shading units, 680 TMUs, 176 ROPs, 170 RT cores, and 680 tensor cores. The Arc G3 has 1280 shading units, 40 TMUs, 20 ROPs, 10 RT cores, and no tensor cores. Pixel rate is 423.6 GPixel/s for the RTX 5090 versus 48.00 GPixel/s for the Arc G3. Texture rate is 1,636.8 GTexel/s versus 96.00 GTexel/s. FP16 throughput is 104.8 TFLOPS (1:1) for the RTX 5090 versus 12.29 TFLOPS (2:1) for the Arc G3.

Power and physical specifications also diverge. The RTX 5090 has a 575 W TDP, is dual-slot, uses a 16-pin power connector, requires a 950 W PSU, and measures 304 mm by 137 mm by 40 mm. The Arc G3 has a 25 W TDP, is an IGP, uses no power connectors, and has no listed dimensions. The RTX 5090 uses PCIe 5.0 x16 while the Arc G3 uses IGP. Display outputs are 1x HDMI 2.1b and 3x DisplayPort 2.1b for the RTX 5090, versus portable device dependent for the Arc G3.

Architecture Differences

The architecture gap is fundamental. The RTX 5090 uses NVIDIA's Blackwell 2.0 architecture on the GB202 chip, manufactured by TSMC on a 5 nm process. The Arc G3 uses Intel's Xe3-LPG architecture on the Panther Lake chip, manufactured by Intel on a 3 nm process. The node difference favors Intel in density terms, but the NVIDIA chip's sheer scale overwhelms any process advantage.

The RTX 5090 belongs to the GeForce 50-series and the GeForce 50 generation, with a predecessor in the GeForce 40 and a successor in the GeForce 60. The Arc G3 belongs to the Arc Graphics-M (Panther Lake) generation with no listed predecessor or successor. The RTX 5090's transistor count of 92,200 million on 750 mm² gives it a density of 122.9M per mm². The Arc G3's transistor count and die size are unknown, but its integrated nature suggests a far smaller allocation.

Cache and memory hierarchy details are not fully recorded for either card, but the memory types alone show a clear architectural split. The RTX 5090 uses dedicated GDDR7 with a 512-bit interface, while the Arc G3 shares system memory, making its bandwidth dependent on the host platform. The RTX 5090's tensor cores (680) support AI workloads, while the Arc G3 lists no tensor core hardware. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is equal.

The RTX 5090's FP16 throughput matches its FP32 at 104.8 TFLOPS (1:1), indicating full-rate half-precision execution. The Arc G3's FP16 is 12.29 TFLOPS (2:1), meaning it runs half-rate. This difference matters for compute tasks that leverage FP16, such as certain machine learning and image processing workloads.

The Verdict

The data is unambiguous. The RTX 5090 outperforms the Arc G3 in every recorded benchmark and every quantifiable specification. Its 104.8 TFLOPS FP32, 1.79 TB/s bandwidth, and 92nd percentile ranking place it among the top graphics cards in the database. The nearest rivals in the database, the Tesla P100 PCIe 16 GB and AMD Radeon RX 6850M XT, score within 1.1 percent of the RTX 5090's average, confirming it sits at the high end of a competitive field.

The Arc G3 has no recorded benchmarks, no average score, and no nearest rivals. Its 50th percentile ranking is a default value, not a measured result. The integrated part delivers 6.144 TFLOPS FP32, 96.00 GTexel/s, and 48.00 GPixel/s, which positions it for light workloads on portable devices. Its 25 W TDP makes it suitable for systems where the RTX 5090's 575 W requirement is impossible.

The choice comes down to system type, not preference. A desktop build with PCIe 5.0 x16, a 950 W PSU, and space for a dual-slot 304 mm card should use the RTX 5090. A portable device with integrated graphics, no power connectors, and system shared memory should use the Arc G3. The RTX 5090's launch MSRP is 1,999 USD. The Arc G3 has no listed launch MSRP.

No benchmark scenario in the database favors the Arc G3. The RTX 5090 wins on compute, memory, texturing, pixel fill, and every recorded test. The Arc G3 wins only on power draw and form factor, which are not performance metrics. For any workload that requires graphics acceleration beyond basic display output, the RTX 5090 is the only choice. The Arc G3 serves a different purpose entirely, providing integrated graphics capability where a discrete card cannot fit.
