Intel Data Center GPU Max Subsystem vs NVIDIA GeForce RTX 5080 SUPER Comparison

Head-to-Head Benchmarks

The head-to-head benchmark data for these two accelerators is extremely limited. The database contains no direct comparison results between the Intel Data Center GPU Max Subsystem and the NVIDIA GeForce RTX 5080 SUPER. The Intel part has no recorded benchmark scores at all, registering an average benchmark score of 0 and a percentile rank of 50 among all GPUs. The NVIDIA card has exactly one recorded benchmark result: a 3DMark Steel Nomad DX12 score of 3075.

That lone score places the RTX 5080 SUPER in the 19th percentile of all GPUs in the database, which is a surprisingly low position. The nearest rivals for the RTX 5080 SUPER in that specific test are revealing. The NVIDIA Quadro P1000 scores 3163, which is 2.8 percent higher. The Intel Arc Pro B60 scores 3182, which is 3.4 percent higher. Conversely, the NVIDIA GeForce 820A scores 2983, which is 3.1 percent lower, and the NVIDIA GeForce GTX 860M scores 2967, which is 3.6 percent lower. The RTX 5080 SUPER sits almost exactly in the middle of this narrow cluster, within a few percentage points of four older or lower-tier parts.

The data indicates that the RTX 5080 SUPER is not demonstrating dominant performance in the Steel Nomad test, at least not relative to the limited set of competitors recorded in the database. Its score of 3075 is sandwiched between the 820A and the Quadro P1000, with margins of only a few percent. This is a narrow band of results, and the 5080 SUPER does not break away from these rivals. Without any recorded benchmarks for the Intel Data Center GPU Max Subsystem, there is no numerical basis for a direct comparison between the two products in this section. The wins tally shows zero for each side, reflecting the absence of head-to-head data.

Where Each One Wins

Given the lack of overlapping benchmark data, the use-case split must be inferred from the recorded specifications rather than from measured performance. The Intel Data Center GPU Max Subsystem is built around a different set of priorities. It offers 128 GB of HBM2e memory across an 8192-bit bus, delivering 3.21 TB/s of bandwidth. The RTX 5080 SUPER, by contrast, has 24 GB of GDDR7 memory on a 256-bit bus, producing 1.02 TB/s of bandwidth. The Intel part provides over four times the memory capacity and over three times the memory bandwidth. For workloads that require massive datasets resident on the GPU, such as large model inference or scientific computing, the Intel part has a clear structural advantage.

The RTX 5080 SUPER counters with higher clock speeds. Its base clock is 2295 MHz and its boost clock is 2617 MHz, compared to the Intel part's 900 MHz base and 1600 MHz boost. The NVIDIA card also has a much higher pixel rate, 293.1 GPixel/s versus the Intel part's 0 MPixel/s, which indicates the Intel Data Center GPU Max Subsystem has no rasterization output stage at all. The Intel part also has no display outputs, making it unsuitable for any interactive graphics work. The RTX 5080 SUPER has 1x HDMI 2.1b and 3x DisplayPort 2.1b outputs.

For floating-point compute, the numbers are close. The Intel part delivers 52.43 TFLOPS FP32 and 52.43 TFLOPS FP16. The RTX 5080 SUPER delivers 56.28 TFLOPS FP32 and 56.28 TFLOPS FP16. The NVIDIA card is roughly 7.3 percent ahead in raw FP32 throughput, a modest margin. The Intel part has more shading units, 16384 versus 10752, and more TMUs, 1024 versus 336, but those resources do not translate into a compute advantage because the clocks are much lower. The texture rate for the Intel part is 1,638.4 GTexel/s, while the RTX 5080 SUPER manages 879.3 GTexel/s. The Intel part wins on texture throughput, nearly doubling the NVIDIA card.

The RTX 5080 SUPER has tensor cores, 336 of them, while the Intel part has no listed tensor core count. The Intel part does have 128 RT cores, compared to 84 on the NVIDIA card. The RTX 5080 SUPER also supports Vulkan 1.4 and DirectX 12 Ultimate, while the Intel part supports DirectX 12 (12_1) and has no Vulkan support listed.

Architecture Differences

The two products come from fundamentally different design philosophies. The Intel Data Center GPU Max Subsystem uses the Ponte Vecchio chip, built on Intel's Generation 12.5 architecture and manufactured on a 10 nm process at Intel's own foundry. The die is 1280 mm² with 100,000 million transistors, giving a transistor density of 78.1 million per square millimeter. The NVIDIA GeForce RTX 5080 SUPER uses the GB203 chip, based on the Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. The die is 378 mm² with 45,600 million transistors, resulting in a density of 120.6 million per square millimeter.

The transistor density difference is substantial. The NVIDIA part packs roughly 54 percent more transistors per square millimeter, reflecting the more advanced 5 nm process node. The Intel die is over three times larger in area and contains over twice as many total transistors. The Intel part uses HBM2e memory, which enables the 8192-bit bus width and the 3.21 TB/s bandwidth figure. The NVIDIA part uses GDDR7, which requires a much narrower 256-bit bus and achieves 1.02 TB/s.

The Intel part is designed as a compute accelerator with no display outputs and no rasterization hardware, as indicated by the 0 MPixel/s pixel rate. The RTX 5080 SUPER is a full graphics card with ROPs, pixel output, and display connectivity. The Intel part has no listed Vulkan API support, while the NVIDIA card supports Vulkan 1.4. Both use PCIe 5.0 x16 and a dual-slot form factor, and both use a single 16-pin power connector. The power requirements differ drastically, with the Intel part rated at 2400 W TDP and a suggested power supply of 2800 W, while the RTX 5080 SUPER is rated at 415 W TDP with no suggested PSU listed.

The release dates are far apart. The Intel Data Center GPU Max Subsystem launched on January 9, 2023. The RTX 5080 SUPER has a release date of December 31, 2025. The Intel part lists a successor, the H3C Graphics, while the NVIDIA card has no successor listed. The production status for both is Active.

The Verdict

The data supports a clear split based on workload type. For anyone building a system around interactive graphics, rendering to a display, or gaming, the RTX 5080 SUPER is the only viable choice between these two. The Intel part has no display outputs, no pixel rate, and no Vulkan support. The RTX 5080 SUPER offers a standard set of display outputs, DirectX 12 Ultimate support, and a recorded benchmark score of 3075 in 3DMark Steel Nomad, even if that score places it near several older GPUs in the database.

For compute-heavy workloads that need large memory capacity and massive bandwidth, the Intel Data Center GPU Max Subsystem has a structural advantage. Its 128 GB of HBM2e memory and 3.21 TB/s bandwidth are far beyond the RTX 5080 SUPER's 24 GB and 1.02 TB/s. The Intel part also has more RT cores, 128 versus 84, and a higher texture rate, 1,638.4 GTexel/s versus 879.3 GTexel/s. The floating-point performance is close, with the NVIDIA card leading by a small margin, 56.28 TFLOPS versus 52.43 TFLOPS in both FP32 and FP16.

The power envelope is a major differentiator. The Intel part draws 2400 W and requires a 2800 W power supply, which is a data center class requirement. The RTX 5080 SUPER is rated at 415 W, making it feasible for a conventional desktop system. The Intel part also has a much larger physical footprint in terms of die size, 1280 mm² versus 378 mm², and a much higher transistor count, 100,000 million versus 45,600 million.

The benchmark data does not resolve the performance question. The RTX 5080 SUPER has one recorded score, and the Intel part has none. The percentile ranks reflect this gap. The Intel part sits at the 50th percentile with an average score of 0, which is a placeholder rather than a measured result. The RTX 5080 SUPER sits at the 19th percentile with its single score. Neither figure provides a reliable basis for predicting relative performance in real workloads. The specifications must carry the analysis.
