Intel Arc G3 vs NVIDIA RTX PRO 4500 Blackwell Comparison

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark runs between the Intel Arc G3 and the NVIDIA RTX PRO 4500 Blackwell. This means the comparison must be built from the recorded benchmark scores for the RTX PRO 4500 and the architectural specifications of the Arc G3, which carries no benchmark entries of its own. The Arc G3 sits at the 50th percentile among all GPUs in the database with an average benchmark score of 0, indicating no submitted results. The RTX PRO 4500, by contrast, holds the 76th percentile with an average score of 31,532.

For the RTX PRO 4500, the recorded data shows a 3DMark Steel Nomad DX12 result of 7,025 points. Its Geekbench Vulkan score reaches 221,768. Passmark results break down by DirectX version: DirectX 9 scores 397, DirectX 10 scores 204, DirectX 11 scores 320, and DirectX 12 scores 119. The G2D score is 1,336, the G3D score is 33,360, and the GPU compute score is 19,255. These figures establish a performance envelope that the Arc G3 cannot directly contest, given the absence of any recorded scores for the Intel part.

The nearest rivals to the RTX PRO 4500 in the database provide context. The NVIDIA TITAN RTX averages 31,676, which is 0.5% lower than the RTX PRO 4500. The NVIDIA GRID M60-1Q averages 31,220, 1% higher. The NVIDIA Quadro M5000 also averages 31,206, 1% higher. The Intel Arc Pro A30M averages 31,894, which is 1.1% lower. These deltas are narrow, all within a 2.1 percentage point band, indicating that the RTX PRO 4500 clusters tightly with these established workstation and professional cards. The data suggests the RTX PRO 4500 is a mid-pack professional GPU, not an outlier at either extreme.

Because the Arc G3 has no benchmarks, the head-to-head section must rely on the theoretical throughput ceilings derived from its clock and shader configuration. The Arc G3's FP32 throughput is 6.144 TFLOPS. The RTX PRO 4500 delivers 50.53 TFLOPS, which is roughly 8.2 times higher. Pixel rate tells a similar story: the Arc G3 outputs 48.00 GPixel/s while the RTX PRO 4500 reaches 269.6 GPixel/s, a ratio of about 5.6 to 1. Texture rate for the Arc G3 is 96.00 GTexel/s versus 789.5 GTexel/s for the RTX PRO 4500, an 8.2 fold gap. These are not measured comparisons, but they are the only quantitative basis available for a direct contrast.

Architecture Differences

The two GPUs come from different manufacturers and different silicon generations. The Arc G3 uses the Panther Lake chip built on Intel's Xe3-LPG architecture, fabricated on a 3 nm process at Intel's own foundry. The RTX PRO 4500 uses the GB203 chip with Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. Transistor counts diverge sharply: the Arc G3's transistor count is unknown in the database, while the RTX PRO 4500 carries 45,600 million transistors on a 378 mm² die, giving a transistor density of 120.6 million per mm².

Core configurations differ in every category. The Arc G3 has 1,280 shading units, 40 texture mapping units, 20 raster output units, and 10 ray tracing cores. The RTX PRO 4500 has 10,496 shading units, 328 TMUs, 112 ROPs, and 82 RT cores. The RTX PRO 4500 also includes 328 tensor cores, while the Arc G3 has no tensor core count recorded. These numbers scale with the overall throughput differences: the RTX PRO 4500 has roughly 8.2 times the shading units and 8.2 times the texture units, while its ROP count is 5.6 times higher.

Memory architecture is fundamentally different. The Arc G3 uses system shared memory, meaning it has no dedicated VRAM, no dedicated memory bus width, and bandwidth that depends on the host system. The RTX PRO 4500 uses dedicated GDDR7 memory with a 256 bit bus and fixed bandwidth of 896.0 GB/s. This structural difference affects everything from latency to capacity planning. The Arc G3 cannot exceed what the host system provides, while the RTX PRO 4500 has a fixed 32 GB pool.

Clock behavior also differs. The Arc G3 has a base clock of 300 MHz and a boost clock of 2400 MHz. The RTX PRO 4500 has a base clock of 1635 MHz and a boost clock of 2407 MHz. The RTX PRO 4500's base clock is over five times higher than the Arc G3's base clock, though their boost clocks are close. The Arc G3's low base clock suggests it relies heavily on boost behavior to reach its 6.144 TFLOPS ceiling.

The power envelope separates the two clearly. The Arc G3 is a 25 W integrated graphics processor with no power connectors and an IGP bus interface. The RTX PRO 4500 is a 200 W dual-slot card with a single 16-pin power connector, a PCIe 5.0 x16 interface, and dimensions of 267 mm length, 111 mm height, and 40 mm width.

Where Each One Wins

The RTX PRO 4500 wins on every measured or computable performance metric in the database. Its FP32 throughput is 50.53 TFLOPS, which is 8.2 times the Arc G3's 6.144 TFLOPS. Its texture rate of 789.5 GTexel/s is 8.2 times the Arc G3's 96.00 GTexel/s. Its pixel rate of 269.6 GPixel/s is 5.6 times the Arc G3's 48.00 GPixel/s. The RTX PRO 4500 has 32 GB of dedicated GDDR7 memory with 896.0 GB/s bandwidth; the Arc G3 relies on system shared memory with no fixed bandwidth figure.

The RTX PRO 4500 also holds the 76th percentile among all GPUs, while the Arc G3 sits at the 50th percentile. The RTX PRO 4500's average benchmark score of 31,532 is the only nonzero average in this comparison. Its nearest rivals, all within 1.1% of its score, confirm it belongs in a performance tier that the Arc G3, with no recorded scores, cannot claim.

The Arc G3 wins on power efficiency in absolute terms. Its 25 W TDP is one eighth of the RTX PRO 4500's 200 W TDP. It requires no power connectors and no suggested PSU rating. It also occupies no expansion slot, using an IGP bus interface, which means it fits into portable devices and compact systems where a dual-slot 267 mm card cannot. The Arc G3's release date of 2026-05-31 is later than the RTX PRO 4500's 2025-03-17, so it represents a newer platform generation.

For workloads that fit within system shared memory and low power envelopes, such as basic graphics output or light compute on integrated platforms, the Arc G3's 25 W design is the only one of the two that can operate without discrete power delivery. For any workload requiring sustained throughput, large memory capacity, or dedicated VRAM bandwidth, the RTX PRO 4500 wins decisively.

The Verdict

The data supports a clear separation of roles. The Intel Arc G3 is an integrated graphics processor with a 25 W TDP, no power connectors, and an IGP bus interface. Its 6.144 TFLOPS FP32 and system shared memory place it in the low-power integrated segment. The RTX PRO 4500 Blackwell is a 200 W dual-slot discrete workstation card with 32 GB GDDR7, 896.0 GB/s bandwidth, and 50.53 TFLOPS FP32. Its 76th percentile rank and average score of 31,532 place it firmly in the professional GPU tier, with nearest rivals all within 1.1% of its average.

Users who need a discrete GPU with dedicated memory, high throughput, and DisplayPort 2.1b outputs should select the RTX PRO 4500. It has recorded benchmark results across DirectX 9 through 12, Vulkan, and compute workloads. Users who need graphics in a portable device with no expansion slot and minimal power draw should consider the Arc G3, provided their workload fits within system shared memory and does not require the throughput levels of the RTX PRO 4500. The 50th percentile rank for the Arc G3 reflects the lack of recorded data rather than a measured performance level. The RTX PRO 4500's benchmark results confirm its position; the Arc G3's position remains unmeasured.
