Intel Arc G3 Extreme vs NVIDIA GeForce RTX 5090 SE Comparison

Head-to-Head Benchmarks

The recorded database contains no direct benchmark scores for either the Intel Arc G3 Extreme or the NVIDIA GeForce RTX 5090 SE. Both entries show an average benchmark score of zero and no entries in the head-to-head benchmark field. As a result, there are no measured wins for either product in this comparison. The absence of recorded performance data means the analysis must rely entirely on the architectural specifications and theoretical throughput figures provided in the database.

The theoretical compute figures establish a substantial gap. The RTX 5090 SE delivers 66.94 TFLOPS of FP32 throughput, while the Intel Arc G3 Extreme reaches 7.680 TFLOPS. This places the NVIDIA part at approximately 8.7 times the single-precision compute rate of the Intel part, based on the recorded numbers. In FP16 compute, the NVIDIA card again shows 66.94 TFLOPS with a 1:1 ratio, while the Intel part achieves 15.36 TFLOPS with a 2:1 ratio, meaning the NVIDIA part holds a 4.36 times advantage in that metric.

Pixel and texture throughput follow the same pattern. The RTX 5090 SE records a pixel rate of 380.3 GPixel/s against 60.00 GPixel/s for the Intel part, a 6.34 times advantage. Texture rate shows 1,045.9 GTexel/s for NVIDIA versus 120.0 GTexel/s for Intel, an 8.72 times difference. The RTX 5090 SE also carries 160 ROPs versus 24 ROPs, and 440 TMUs versus 48 TMUs.

Both entries occupy the 50th percentile among all GPUs in the database, but that percentile is based on incomplete data. The percentile field exists for both parts, but with no benchmark scores recorded, the percentile value likely reflects the position of the database entry rather than actual measured performance. The nearest rivals fields are empty for both products, so no direct comparison scores or delta percentages are available.

Architecture Differences

The two products come from fundamentally different design philosophies. The Intel Arc G3 Extreme uses the Panther Lake chip with Xe3-LPG architecture, part of the Arc Graphics-M (Panther Lake) generation. It is built on a 3 nm process at Intel's own foundry. The NVIDIA GeForce RTX 5090 SE uses the GB202 chip with Blackwell 2.0 architecture, part of the GeForce 50 series, fabricated on a 5 nm process at TSMC. The Intel part is a newer process node, but the NVIDIA chip carries far more hardware.

Transistor counts differ dramatically. The RTX 5090 SE packs 92,200 million transistors on a 750 mm² die, with a transistor density of 122.9M per mm². The Intel Arc G3 Extreme lists transistor count and die size as unknown in the database. This makes direct density comparisons impossible, but the NVIDIA die is physically large and dense.

The Intel part is an integrated graphics processor with an IGP bus interface and IGP slot width. It uses system-shared memory with system-dependent bandwidth, meaning it has no dedicated VRAM. The NVIDIA card is a dual-slot discrete GPU with a PCIe 5.0 x16 interface, 24 GB of GDDR7 memory on a 384-bit bus, and 1.34 TB/s of dedicated bandwidth. The RTX 5090 SE also has 110 RT cores and 440 tensor cores, while the Intel part has 12 RT cores and no tensor cores listed in the database.

Clock behavior differs. The Intel Arc G3 Extreme has a base clock of 300 MHz and a boost clock of 2500 MHz. The RTX 5090 SE starts at 1740 MHz base and boosts to 2377 MHz. The Intel part boosts higher but starts much lower, reflecting its integrated low-power design. The NVIDIA memory clock is listed as 1750 MHz with 28 Gbps effective speed, while the Intel memory clock is system shared.

Power and physical requirements starkly contrast. The Intel Arc G3 Extreme has a TDP of 80 W, no power connectors, and no suggested PSU. The RTX 5090 SE draws 500 W, requires a single 16-pin connector, and the database lists a 900 W suggested PSU. The NVIDIA card measures 267 mm in length, 111 mm in height, and 40 mm in width. The Intel part lists no physical dimensions because it is an integrated design.

Display outputs differ as well. The RTX 5090 SE provides 1x HDMI 2.1b and 3x DisplayPort 2.1b. The Intel Arc G3 Extreme lists display outputs as portable device dependent, meaning it relies on the host system for connectivity. Both parts support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical.

The Verdict

Based strictly on the recorded specifications, the NVIDIA GeForce RTX 5090 SE is the clear performance leader. Its FP32 compute is 8.7 times higher, pixel rate is 6.34 times higher, texture rate is 8.72 times higher, and it carries more than ten times the shading units (14,080 versus 1,536). The RTX 5090 SE also has 110 RT cores versus 12, and 440 tensor cores versus none. Memory bandwidth is dedicated at 1.34 TB/s rather than system dependent.

The Intel Arc G3 Extreme serves a different function. As an integrated GPU on a 3 nm node with 80 W TDP, it targets portable devices where discrete graphics is impossible. Its 300 MHz base clock and 2500 MHz boost clock suggest a power-efficient design. The 15.36 TFLOPS FP16 performance with a 2:1 ratio indicates it handles half-precision workloads reasonably well for its class.

The RTX 5090 SE launches at a list price of 1,499 USD, though pricing is not a factor in this analysis. Its release date is recorded as December 2025, while the Intel part is dated May 2026. The NVIDIA card has a predecessor in the GeForce 40 series and a successor in the GeForce 60 series. The Intel part has no predecessor or successor listed in the database.

Users needing maximum frame rates, ray tracing, or AI acceleration should choose the RTX 5090 SE. The data shows it dominates every measured compute metric. Users requiring an integrated solution with minimal power draw should consider the Intel Arc G3 Extreme, which consumes 6.25 times less power and requires no separate power connector or PCIe slot.
