Intel Arc G3 vs NVIDIA RTX 4500 Ada Generation Comparison

Head-to-Head Benchmarks

The recorded database contains no direct head-to-head benchmark results between the Intel Arc G3 and the NVIDIA RTX 4500 Ada Generation. The head-to-head benchmark array is empty, and neither part has a wins count in this pairing. However, the RTX 4500 Ada Generation has two individual benchmark scores stored in the database: Geekbench OpenCL at 160,786 and Geekbench Vulkan at 171,401. These combine to an average benchmark score of 166,094, placing it at the 97th percentile among all GPUs.

The Arc G3 has no individual benchmark scores on file, and its average benchmark score is recorded as 0. Its percentile placement is 50th, which suggests it sits near the middle of the database distribution, though without recorded scores this percentile is largely informational. The RTX 4500 Ada Generation outperforms its nearest rivals by small margins. It sits 0.5% ahead of the NVIDIA RTX A5500, which averages 165,217. It leads the AMD Radeon PRO W7800 (164,894) by 0.7%. The AMD Radeon Pro W6900X posts a higher average score of 168,574, placing it 1.5% ahead of the RTX 4500 Ada Generation. The NVIDIA A100 PCIe 40 GB trails by 2.2% with an average score of 162,504.

Since no direct comparison scores exist, the practical benchmark difference must be inferred from architectural capacity and raw throughput figures. The RTX 4500 Ada Generation delivers 39.63 TFLOPS of FP32 compute, while the Arc G3 delivers 6.144 TFLOPS. That is a factor of roughly 6.45 in raw floating-point throughput. Pixel throughput similarly favors the Ada card: 206.4 GPixel/s against 48.00 GPixel/s. Texture rate stands at 619.2 GTexel/s versus 96.00 GTexel/s. These figures indicate the RTX 4500 Ada Generation occupies a different performance class entirely, even without a shared benchmark entry.

Architecture Differences

The two GPUs come from different manufacturers, foundries, and process nodes. Intel builds the Arc G3 on a 3 nm process at its own foundry, using the Xe3-LPG architecture and the Panther Lake chip. The GPU belongs to the Arc Graphics-M (Panther Lake) generation. NVIDIA builds the RTX 4500 Ada Generation on a 5 nm process at TSMC, using the Ada Lovelace architecture and the AD103 chip. The NVIDIA part is listed under the Workstation Ada generation and the GeForce 40-series family.

The RTX 4500 Ada Generation integrates 45,900 million transistors on a 379 mm² die, with a transistor density of 121.1M per mm². The Arc G3 has unknown transistor count, die size, and density in the database. The NVIDIA GPU uses 24 GB of GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s of bandwidth. The Arc G3 relies on system shared memory, with its bus width and memory type also system shared. Its memory bandwidth is system dependent.

Compute resources differ substantially. The Arc G3 has 1,280 shading units, 40 texture mapping units, 20 ROPs, and 10 ray tracing cores. The RTX 4500 Ada Generation has 7,680 shading units, 240 TMUs, 80 ROPs, and 60 RT cores. The NVIDIA card also includes 240 tensor cores, while the Arc G3 lists no tensor core count. The FP16 data path differs: the Arc G3 achieves 12.29 TFLOPS via a 2:1 ratio, while the NVIDIA card reaches 39.63 TFLOPS at a 1:1 ratio.

Clock behavior also separates the two. The Arc G3 runs at a 300 MHz base and 2400 MHz boost. The RTX 4500 Ada Generation runs at 2070 MHz base and 2580 MHz boost. Memory clock for the NVIDIA card is listed at 2250 MHz with 18 Gbps effective. The Arc G3 has no dedicated memory clock because it uses shared system memory.

Power and physical specifications diverge sharply. The Arc G3 has a 25 W TDP and is an integrated graphics processor (IGP) with no power connectors and no slot width beyond the IGP designation. The RTX 4500 Ada Generation has a 210 W TDP, a suggested 550 W power supply, dual-slot width, no power connectors listed, and a PCIe 4.0 x16 bus interface. The NVIDIA card measures 245 mm (9.6 inches) in length and 112 mm (4.4 inches) in height. The Arc G3 has no dimensions listed.

API support is identical on paper: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ, with the Arc G3 using portable device dependent outputs and the RTX 4500 Ada Generation providing 4x DisplayPort 1.4a.

Release dates differ by roughly three years. The RTX 4500 Ada Generation launched in August 2023, while the Arc G3 appears with a release date of May 2026. The NVIDIA card lists its predecessor as Workstation Ampere and its successor as Blackwell PRO W. The Arc G3 has no predecessor or successor listed.

The Verdict

The data shows two products in different classes. The RTX 4500 Ada Generation is a discrete workstation card with dedicated GDDR6 memory, 24 GB capacity, 7,680 shading units, 240 tensor cores, and a 97th percentile placement. The Arc G3 is an integrated GPU with 1,280 shading units, system shared memory, no tensor cores, and a 50th percentile placement.

For any application that relies on raw compute throughput, memory bandwidth, or ray tracing resources, the RTX 4500 Ada Generation is the clear choice. Its 39.63 TFLOPS of FP32, 432.0 GB/s bandwidth, and 60 RT cores provide a substantial margin over the Arc G3's 6.144 TFLOPS, system dependent bandwidth, and 10 RT cores.

The Arc G3's strengths are in integration and power efficiency. Its 25 W TDP fits within a mobile or integrated context, and its system shared memory approach removes the need for dedicated VRAM allocation. The RTX 4500 Ada Generation requires a 210 W TDP, a 550 W suggested power supply, dual-slot space, and a PCIe 4.0 x16 slot.

The RTX 4500 Ada Generation also has recorded benchmark data supporting its performance, with Geekbench OpenCL at 160,786 and Geekbench Vulkan at 171,401. The Arc G3 has no recorded benchmark scores in the database. Buyers needing verified workstation performance should rely on the NVIDIA card's documented results.

Where Each One Wins

The RTX 4500 Ada Generation wins in every compute-heavy category recorded. Its FP32 throughput of 39.63 TFLOPS is roughly 6.45 times the Arc G3's 6.144 TFLOPS. Pixel fill rate of 206.4 GPixel/s is over four times the Arc G3's 48.00 GPixel/s. Texture rate of 619.2 GTexel/s is over six times the Arc G3's 96.00 GTexel/s. The NVIDIA card also provides 60 RT cores and 240 tensor cores, where the Arc G3 has 10 RT cores and no tensor cores.

Memory capacity and bandwidth favor NVIDIA decisively. The 24 GB GDDR6 pool with 432.0 GB/s bandwidth supports large datasets and high-resolution textures. The Arc G3 depends on system shared memory with bandwidth that varies by platform.

The Arc G3 wins in power efficiency and integration. Its 25 W TDP is dramatically lower than the 210 W TDP of the NVIDIA card. It requires no additional power connectors, no dedicated slot, and no external power supply recommendation. As an IGP, it fits directly into a portable device with no physical expansion requirements.

The Arc G3 also wins on release recency, with a 2026 launch date versus the NVIDIA card's 2023 launch. Its 3 nm process node is smaller than the 5 nm node used by the RTX 4500 Ada Generation.

For software environments that depend on documented, verified performance, the RTX 4500 Ada Generation has the advantage of recorded Geekbench OpenCL and Vulkan scores. The Arc G3 lacks any recorded benchmark entries. For integrated, low-power deployments where discrete GPU installation is impossible, the Arc G3 is the only viable option between the two.
