Intel Arc G3 Extreme vs NVIDIA RTX PRO 4500 Blackwell Server Comparison

Head-to-Head Benchmarks

The database contains no recorded benchmark scores for either the Intel Arc G3 Extreme or the NVIDIA RTX PRO 4500 Blackwell Server. Both products hold an identical 50th percentile ranking against all GPUs in the database, with an average benchmark score of zero for each. With zero wins registered for either side in the head-to-head comparison matrix, the recorded data offers no direct performance deltas to report. What can be analyzed instead are the theoretical compute ceilings derived from the specification sheets, which reveal a substantial gulf in raw throughput.

The FP32 floating-point performance gap is the most pronounced differentiator. The NVIDIA RTX PRO 4500 delivers 50.70 TFLOPS, which is roughly 6.6 times the 7.680 TFLOPS of the Intel Arc G3 Extreme. In FP16 workloads, the NVIDIA part maintains its 50.70 TFLOPS at a 1:1 ratio, meaning it processes half-precision data at the same rate as single-precision. The Intel part reaches 15.36 TFLOPS FP16 at a 2:1 ratio, doubling its FP32 rate. Even with that doubling, the NVIDIA card still holds roughly a 3.3 times advantage in FP16 throughput. Texture and pixel fill rates follow the same pattern. The RTX PRO 4500 achieves 792.1 GTexel/s and 270.5 GPixel/s, versus 120.0 GTexel/s and 60.00 GPixel/s for the Intel part. That translates to a 6.6 times lead in texturing and a 4.5 times lead in rasterization throughput.

Memory bandwidth widens the divide further. The NVIDIA card uses 32 GB of GDDR7 on a 256 bit bus, yielding 800.3 GB/s of bandwidth. The Intel part uses system shared memory, with bandwidth classified as system dependent. That means the Arc G3 Extreme's memory performance cannot be stated as a fixed number; it varies with the host platform's memory configuration. The RTX PRO 4500 also has a fixed 1563 MHz memory clock at 25 Gbps effective, while the Intel part's memory clock is listed as system shared with no fixed value. For any workload that saturates memory bandwidth, the NVIDIA card's dedicated 800.3 GB/s pool presents a decisive structural advantage.

The Verdict

The data points to a clear stratification by intended use case. The NVIDIA RTX PRO 4500 Blackwell Server is engineered for compute-heavy server deployments where raw FP32, FP16, ray tracing, and memory bandwidth are the dominant constraints. Its 50.70 TFLOPS FP32, 50.70 TFLOPS FP16, 800.3 GB/s memory bandwidth, and 82 RT cores place it in a performance class that the Intel Arc G3 Extreme cannot approach on paper. The Intel part, with its 7.680 TFLOPS FP32, 15.36 TFLOPS FP16, system shared memory, and 12 RT cores, is a fundamentally lighter compute unit. Its 80 W TDP, IGP form factor, and lack of dedicated power connectors suggest a design for compact, power-constrained systems where the GPU shares system memory rather than owning a private pool.

For users needing maximum server-side compute density, the RTX PRO 4500 is the only viable option from this pair. Its 165 W TDP in a single-slot, 267 mm card with a 16-pin connector and 450 W suggested PSU indicates a self-contained accelerator that fits standard server chassis. The Intel Arc G3 Extreme, with no power connectors and an IGP bus interface, is not a discrete card at all; it is an integrated GPU. The recorded production status for both parts is active, but their form factors address different hardware tiers. The RTX PRO 4500's predecessor is listed as Server Hopper and its successor as Server Rubin, confirming its placement in NVIDIA's server accelerator lineage. The Intel part carries no predecessor or successor entries in the database.

Architecture Differences

The two chips come from different foundries and process nodes. Intel fabricates the Arc G3 Extreme on a 3 nm node at Intel, using the Panther Lake chip with the Xe3-LPG architecture. NVIDIA builds the RTX PRO 4500 on a 5 nm node at TSMC, using the GB203 chip with the Blackwell 2.0 architecture. The process node difference does not automatically determine performance, but the architectural intent differs sharply.

The NVIDIA part integrates 45,600 million transistors on a 378 mm² die, producing a transistor density of 120.6 million transistors per square millimeter. The Intel part's transistor count and die size are listed as unknown in the database, so no density comparison is possible. What is clear is the execution resource allocation. NVIDIA's Blackwell 2.0 design fields 10,496 shading units, 328 TMUs, 112 ROPs, 82 RT cores, and 328 tensor cores. Intel's Xe3-LPG design fields 1,536 shading units, 48 TMUs, 24 ROPs, and 12 RT cores, with no tensor core count recorded.

The RT core disparity is notable for ray tracing workloads. The NVIDIA card's 82 RT cores versus the Intel part's 12 RT cores represents a 6.8 times difference in dedicated ray tracing hardware. Tensor core availability also separates the two: the NVIDIA part has 328 tensor cores for AI acceleration, while the Intel part lists no tensor core count at all. For FP16 compute, the NVIDIA architecture runs at a 1:1 ratio with FP32, meaning no throughput penalty for half-precision work. The Intel architecture uses a 2:1 ratio, halving its throughput when moving from FP32 to FP16. These architectural choices explain the massive compute gaps despite the Intel part's smaller process node.

Specification Differences

The two products diverge across nearly every specification field. The NVIDIA RTX PRO 4500 uses 32 GB of GDDR7 memory on a 256 bit bus with 800.3 GB/s bandwidth, while the Intel Arc G3 Extreme uses system shared memory with system dependent bandwidth. The NVIDIA card's base clock is 1215 MHz with a 2415 MHz boost, while the Intel part runs at a 300 MHz base and 2500 MHz boost. The boost clocks are close, but the base clocks differ by a factor of four.

Power delivery separates them completely. The NVIDIA card has a 165 W TDP, a single-slot form factor, one 16-pin power connector, and a 450 W suggested PSU. The Intel part has an 80 W TDP, an IGP form factor, no power connectors, and no suggested PSU listed. The bus interface differs as well: NVIDIA uses PCIe 5.0 x16, while Intel uses IGP. Display outputs also diverge: the NVIDIA card has no outputs, while the Intel part's outputs are portable device dependent. The NVIDIA card measures 267 mm in length, 111 mm in height, and 40 mm in width. The Intel part has no recorded dimensions.

The NVIDIA card's memory clock is fixed at 1563 MHz with 25 Gbps effective data rate. The Intel part's memory clock is listed simply as system shared. Production status for both is active, but the release dates differ, with the NVIDIA part released on 2026-03-16 and the Intel part on 2026-05-31. The NVIDIA part has a predecessor (Server Hopper) and successor (Server Rubin) recorded; the Intel part has neither. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical. Neither product has a launch MSRP recorded in the database.
