AMD Radeon RX 7800M vs NVIDIA GeForce RTX 5080 SUPER Comparison

The Verdict

The recorded data presents an unusual comparison. The AMD Radeon RX 7800M and the NVIDIA GeForce RTX 5080 SUPER occupy entirely different tiers of the mobile and desktop GPU markets, separated by a massive gap in specifications and performance. According to the benchmark database, the NVIDIA GeForce RTX 5080 SUPER holds a single head-to-head win over the AMD Radeon RX 7800M in the 3DMark Steel Nomad DX12 test, scoring 3075 against 2994, a delta of -2.6% from the AMD card's perspective. This is a narrow margin, but the surrounding data tells a much larger story.

The AMD Radeon RX 7800M is an integrated graphics processor, listed with a slot width of "IGP" and no power connectors, designed for portable devices. Its average benchmark score across ten different tests is 27883, placing it in the 73rd percentile of all GPUs. The NVIDIA GeForce RTX 5080 SUPER, by contrast, is a dual-slot, 415 W discrete card with a 16-pin power connector, featuring a 24 GB GDDR7 memory configuration. Its single recorded benchmark score is 3075, which places it in the 19th percentile, but this percentile figure is based on only one test and is misleading given the card's raw specifications. The RTX 5080 SUPER shows a transistor count of 45,600 million, a 62.2% increase over the AMD chip's 28,100 million, and delivers 56.28 TFLOPS of FP32 compute versus 35.87 TFLOPS for the RX 7800M.

The data indicates that the RTX 5080 SUPER is the more powerful GPU in raw terms, but the RX 7800M offers a far more complete benchmark profile. The verdict, strictly from the data, is that the RX 7800M is the sensible choice for portable, integrated graphics scenarios where power draw and physical footprint are constrained. The RTX 5080 SUPER is the choice for maximum performance in a desktop environment, with its higher memory capacity, faster memory bandwidth, and greater compute throughput. The benchmark database shows the NVIDIA card wins the only shared test, but the AMD card's broader set of results across DirectX 10, 11, 12, 9, and compute workloads provides a more complete picture of its capabilities in diverse applications.

Where Each One Wins

The AMD Radeon RX 7800M wins in the domain of integrated graphics practicality. It is an IGP-class part with a 180 W TDP, no power connectors, and dimensions that are portable-device dependent. Its benchmark suite includes ten results spanning legacy and modern APIs, with notable scores in Geekbench OpenCL at 120778 and Geekbench Vulkan at 126668. These scores indicate strong compute and graphics performance for an integrated solution. The RX 7800M also shows a PassMark G3D score of 17613 and a PassMark G2D score of 892, giving it a well-rounded profile for general graphics tasks.

The NVIDIA GeForce RTX 5080 SUPER wins in raw performance and memory capacity. It features 24 GB of GDDR7 memory on a 256-bit bus, delivering 1.02 TB/s of bandwidth, which is 2.36 times the 432.0 GB/s of the RX 7800M. Its 10752 shading units, 336 TMUs, and 112 ROPs dwarf the RX 7800M's 3840 shading units, 240 TMUs, and 96 ROPs. The RTX 5080 SUPER also includes 336 tensor cores and 84 RT cores, compared to the RX 7800M's 60 RT cores and no tensor cores. In the single head-to-head benchmark, the RTX 5080 SUPER wins the 3DMark Steel Nomad DX12 test with a score of 3075 versus 2994.

The data implies a clear split: the RX 7800M is optimized for efficiency and integration, while the RTX 5080 SUPER is optimized for peak performance and high-resolution, high-memory workloads. The RX 7800M's nearest rivals in the database include the AMD Radeon Pro Vega 20 with an average score of 27839 and a delta of 0.2%, and the AMD Radeon Pro W5500X with 27973 and a delta of -0.3%. These are professional workstation cards, suggesting the RX 7800M's performance aligns with that tier. The RTX 5080 SUPER's nearest rivals, based on its single score, include the NVIDIA Quadro P1000 with 3163 and a delta of -2.8%, and the Intel Arc Pro B60 with 3182 and a delta of -3.4%, which are lower-tier professional cards, an artifact of the limited benchmark data available for the RTX 5080 SUPER.

Architecture Differences

The two GPUs come from different architectural generations and design philosophies. The AMD Radeon RX 7800M uses the Navi 32 chip built on RDNA 3.0 architecture, with the codename "Wheat Nas" and belongs to the Navi Mobile (RX 7000M) generation. It is fabricated on a 5 nm process at TSMC, with 28,100 million transistors on a 346 mm² die, yielding a transistor density of 81.2M per mm². The chip includes 60 RT cores but no tensor cores, reflecting AMD's focus on rasterization and ray tracing without dedicated AI acceleration hardware in this configuration.

The NVIDIA GeForce RTX 5080 SUPER uses the GB203 chip built on Blackwell 2.0 architecture, part of the GeForce 50 generation. It is also fabricated on a 5 nm process at TSMC, but with a substantially higher transistor count of 45,600 million on a 378 mm² die, resulting in a transistor density of 120.6M per mm². This is a 48.5% higher density than the AMD chip. The RTX 5080 SUPER includes 336 tensor cores, indicating a strong focus on AI and DLSS-style workloads, alongside 84 RT cores.

The memory architectures differ significantly. The RX 7800M uses 12 GB of GDDR6 memory on a 192-bit bus, with a bandwidth of 432.0 GB/s and an effective clock of 18 Gbps. The RTX 5080 SUPER uses 24 GB of GDDR7 memory on a 256-bit bus, with a bandwidth of 1.02 TB/s and an effective clock of 32 Gbps. The GDDR7 memory operates at a lower base memory clock of 2000 MHz but achieves double the effective data rate per pin. The power delivery also diverges: the RX 7800M is an IGP with no power connectors and a 180 W TDP, while the RTX 5080 SUPER is a dual-slot card with a 1x 16-pin power connector and a 415 W TDP.

The bus interfaces differ as well. The RX 7800M uses PCIe 4.0 x16, while the RTX 5080 SUPER uses PCIe 5.0 x16, offering double the bandwidth for data transfer between the GPU and the rest of the system. The physical dimensions reflect their intended use cases: the RX 7800M has no listed length, height, or width, as it is portable-device dependent, while the RTX 5080 SUPER measures 304 mm in length, 137 mm in height, and 40 mm in width.

Head-to-Head Benchmarks

The only direct comparison available in the database is the 3DMark Steel Nomad DX12 test. In this test, the NVIDIA GeForce RTX 5080 SUPER scores 3075, while the AMD Radeon RX 7800M scores 2994. The winner is the NVIDIA card with a delta of -2.6% from the AMD card's perspective. This represents a 2.7% advantage for the RTX 5080 SUPER in this specific workload.

The narrow margin in Steel Nomad is surprising given the vast specification differences. The RTX 5080 SUPER has 2.8 times the shading units, 1.57 times the FP32 throughput, and 2.36 times the memory bandwidth. Yet the score difference is only 81 points. This could indicate that the benchmark is not fully utilizing the RTX 5080 SUPER's capabilities, or that the RX 7800M's architecture is more efficient in this particular test. The RX 7800M's nearest rivals in the database, the AMD Radeon Pro Vega 20 and AMD Radeon Pro W5500X, have average scores of 27839 and 27973 respectively, both within 0.3% of the RX 7800M's 27883 average. The RTX 5080 SUPER's nearest rivals include the NVIDIA Quadro P1000 at 3163 and the Intel Arc Pro B60 at 3182, both around 3% away from its 3075 score.

The broader benchmark suite for the RX 7800M provides additional context. Its PassMark DirectX 11 score of 176 and DirectX 12 score of 89 show that it performs better in older APIs, while its Geekbench OpenCL score of 120778 and Vulkan score of 126668 indicate strong compute performance. The RTX 5080 SUPER has no equivalent scores in the database, limiting direct comparisons to the single Steel Nomad result.
