Intel Arc G3 vs NVIDIA GeForce RTX 5090 D V2 Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark results between the Intel Arc G3 and the NVIDIA GeForce RTX 5090 D V2. The Intel Arc G3 has no benchmark scores listed in the database, while the NVIDIA GeForce RTX 5090 D V2 has a single 3DMark Steel Nomad DX12 score of 16504. This absence of overlapping tests means a direct performance comparison cannot be quantified from the available measurements.

The NVIDIA GeForce RTX 5090 D V2 sits at the 59th percentile of all GPUs in the database. Its nearest rivals, according to the recorded data, are the NVIDIA T400 with an average score of 16508 and a delta of 0 percent, the AMD Radeon PRO W7500 with 16415 and a 0.5 percent delta, the NVIDIA RTX PRO 6000 Blackwell with 16408 and a 0.6 percent delta, and the AMD Radeon RX 5700 XT with 16361 and a 0.9 percent delta. These deltas are negligible, indicating that the RTX 5090 D V2 performs within a single percentage point of these four rivals in the Steel Nomad test. The Intel Arc G3, by contrast, has an average benchmark score of zero and a 50th percentile placement, but the database provides no actual test results to validate this placement.

Without a common benchmark, the only measurable comparison is theoretical compute output. The RTX 5090 D V2 delivers 104.8 TFLOPS of FP32 performance, while the Arc G3 delivers 6.144 TFLOPS. That is a 17-fold difference in raw floating-point throughput. The pixel rate comparison shows 423.6 GPixel/s versus 48.00 GPixel/s, a factor of roughly 8.8. Texture rate stands at 1,636.8 GTexel/s versus 96.00 GTexel/s, a factor of about 17. These raw throughput figures indicate a massive gulf in peak compute capability, but they do not translate directly to real-world frame rates without actual benchmark data.

Architecture Differences

The two GPUs represent fundamentally different design philosophies and market positions. The Intel Arc G3 is an integrated graphics processor built on the Panther Lake chip, using the Xe3-LPG architecture. It belongs to the Arc Graphics-M (Panther Lake) generation and is fabricated on a 3 nm process by Intel. The NVIDIA GeForce RTX 5090 D V2 is a discrete add-in board based on the GB202 chip, using the Blackwell 2.0 architecture, part of the GeForce 50-series. It is fabricated on a 5 nm process by TSMC.

The process node difference is notable: 3 nm for Intel versus 5 nm for NVIDIA. The RTX 5090 D V2 has 92,200 million transistors on a 750 mm² die, giving a transistor density of 122.9 million per square millimeter. The Arc G3's transistor count and die size are listed as unknown, so no density comparison is possible.

Memory architecture differs completely. The Arc G3 uses system-shared memory, with the bus width, type, and bandwidth all listed as system dependent. The RTX 5090 D V2 uses 24 GB of GDDR7 memory on a 384-bit bus, delivering 1.34 TB/s of bandwidth. The Arc G3's memory clock is also system shared, while the RTX 5090 D V2 has a memory clock of 1750 MHz, or 28 Gbps effective.

The compute resources show a similar scale of difference. The Arc G3 has 1280 shading units, 40 texture mapping units, 20 raster output units, and 10 ray tracing cores. The RTX 5090 D V2 has 21760 shading units, 680 TMUs, 176 ROPs, 170 ray tracing cores, and 680 tensor cores. The Arc G3 has no tensor cores listed, while the RTX 5090 D V2's tensor cores enable its FP16 throughput at a 1:1 ratio with FP32. The Arc G3's FP16 output is 12.29 TFLOPS at a 2:1 ratio, meaning it achieves half the FP32 rate for FP16, whereas the RTX 5090 D V2 achieves equal FP16 and FP32 rates.

Clock speeds diverge sharply. The Arc G3 has a base clock of 300 MHz and a boost clock of 2400 MHz. The RTX 5090 D V2 has a base clock of 2017 MHz and a boost clock of 2407 MHz. The Arc G3's boost clock is only 7 MHz lower than the RTX 5090 D V2's boost, but the base clock difference is 1717 MHz in NVIDIA's favor.

Power and physical specifications reflect the discrete versus integrated divide. The Arc G3 has a TDP of 25 W, occupies an IGP slot width, uses no power connectors, and has a bus interface of IGP. The RTX 5090 D V2 has a TDP of 575 W, is dual-slot, uses a single 16-pin power connector, suggests a 950 W power supply, and uses PCIe 5.0 x16. The RTX 5090 D V2 measures 304 mm in length, 137 mm in height, and 48 mm in width. The Arc G3's dimensions are not listed.

Display outputs differ as well. The Arc G3 uses portable device dependent outputs, while the RTX 5090 D V2 provides 1x HDMI 2.1b and 3x DisplayPort 2.1b. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Release dates are close: the RTX 5090 D V2 launched on August 14, 2025, while the Arc G3 is dated May 31, 2026. The RTX 5090 D V2 has a predecessor in the GeForce 40 series and a successor in the GeForce 60 series. The Arc G3 lists no predecessor or successor.

The Verdict

The data indicates two products aimed at entirely different use cases. The Intel Arc G3 is an integrated GPU with modest compute resources, a 25 W power envelope, and system-shared memory. It is designed for portable devices where space and power are constrained. The NVIDIA GeForce RTX 5090 D V2 is a high-end discrete GPU with 21760 shading units, 24 GB of dedicated GDDR7 memory, and a 575 W TDP. It requires a dual-slot cooler, a 16-pin connector, and a 950 W power supply.

For raw compute tasks, the RTX 5090 D V2's recorded specifications dominate. Its FP32 throughput of 104.8 TFLOPS is 17 times the Arc G3's 6.144 TFLOPS. Its pixel rate of 423.6 GPixel/s is 8.8 times the Arc G3's 48.00 GPixel/s. Its texture rate of 1,636.8 GTexel/s is 17 times the Arc G3's 96.00 GTexel/s. The RTX 5090 D V2's single benchmark score of 16504 places it at the 59th percentile, with nearest rivals within one percentage point.

The Arc G3's advantage lies in power efficiency and integration. At 25 W, it consumes 23 times less power than the RTX 5090 D V2's 575 W. It requires no external power connectors and fits in an IGP slot. For a portable device, this is the only viable option between the two. The RTX 5090 D V2 cannot operate in such a form factor.

The RTX 5090 D V2's launch MSRP is 2,299 USD. The Arc G3 has no launch MSRP listed.

Neither product replaces the other. The Arc G3 serves systems where the RTX 5090 D V2 physically cannot fit. The RTX 5090 D V2 serves workloads where the Arc G3's compute resources are insufficient by roughly an order of magnitude. The database shows no benchmark overlap, so a direct performance comparison remains unquantified.
