NVIDIA GeForce RTX 4080 SUPER vs NVIDIA GeForce RTX 5080 SUPER Comparison

Head-to-Head Benchmarks

The database contains one direct benchmark comparison between these two cards, and the result is decisively one-sided. In the 3DMark Steel Nomad DX12 test, the NVIDIA GeForce RTX 4080 SUPER scores 6600, while the NVIDIA GeForce RTX 5080 SUPER scores 3075. That is a 114.6% higher score for the 4080 SUPER, meaning it delivers more than double the performance in this specific workload. The 4080 SUPER wins the only head-to-head benchmark recorded, with a win count of 1 versus 0 for the 5080 SUPER.

Looking at the broader benchmark averages, the 4080 SUPER shows an average benchmark score of 54209 across ten recorded tests, while the 5080 SUPER has an average of 3075 from a single test. This places the 4080 SUPER in the 86th percentile of all GPUs in the database, whereas the 5080 SUPER sits at the 19th percentile. The gap is stark, but it is important to note that the 5080 SUPER has limited recorded data, so its percentile reflects only one benchmark run.

The 4080 SUPER's nearest rivals in the database include the NVIDIA GeForce RTX 4080 at 54247 average score, which is effectively tied with the 4080 SUPER at a delta of -0.1%. The AMD Radeon Pro W5700X comes in at 54828, putting it 1.1% ahead, and the AMD Radeon RX 6750 GRE 12 GB scores 55698, which is 2.7% ahead. The AMD Radeon 8060S reaches 55757, 2.8% ahead. These deltas are small, indicating that the 4080 SUPER performs in a tight cluster with these cards. The 5080 SUPER, by contrast, has nearest rivals at much lower performance levels: the NVIDIA Quadro P1000 at 3163 average score is 2.8% ahead, the NVIDIA GeForce 820A at 2983 is 3.1% behind, the Intel Arc Pro B60 at 3182 is 3.4% ahead, and the NVIDIA GeForce GTX 860M at 2967 is 3.6% behind. This places the 5080 SUPER's recorded performance in a completely different tier.

Architecture Differences

The two cards come from different NVIDIA generations and use different architectures. The RTX 4080 SUPER is based on the AD103 chip using the Ada Lovelace architecture, part of the GeForce 40 series. The RTX 5080 SUPER uses the GB203 chip with the Blackwell 2.0 architecture, part of the GeForce 50 series. Both are fabricated by TSMC on a 5 nm process, and their transistor counts are nearly identical: 45,900 million for the 4080 SUPER versus 45,600 million for the 5080 SUPER. Die sizes are also close, at 379 mm² for the 4080 SUPER and 378 mm² for the 5080 SUPER, giving transistor densities of 121.1M / mm² and 120.6M / mm² respectively.

Core configurations differ meaningfully. The 4080 SUPER has 10240 shading units, 320 TMUs, 112 ROPs, 80 RT cores, and 320 tensor cores. The 5080 SUPER has 10752 shading units, 336 TMUs, 112 ROPs, 84 RT cores, and 336 tensor cores. The 5080 SUPER therefore has more shading units, TMUs, RT cores, and tensor cores, but the same number of ROPs. Clock speeds show a modest difference: both have a base clock of 2295 MHz, but the boost clock is 2550 MHz for the 4080 SUPER and 2617 MHz for the 5080 SUPER, a 67 MHz advantage for the newer card.

Memory configurations are a major differentiator. The 4080 SUPER uses 16 GB of GDDR6X on a 256-bit bus with a memory clock of 1438 MHz (23 Gbps effective) and bandwidth of 736.3 GB/s. The 5080 SUPER uses 24 GB of GDDR7 on the same 256-bit bus, with a memory clock of 2000 MHz (32 Gbps effective) and bandwidth of 1.02 TB/s. That is a substantial increase in capacity and bandwidth, roughly 50% more memory and about 38% more bandwidth for the 5080 SUPER.

Other architectural differences appear in the bus interface and display outputs. The 4080 SUPER uses PCIe 4.0 x16, while the 5080 SUPER uses PCIe 5.0 x16. Display outputs are 1x HDMI 2.1 and 3x DisplayPort 1.4a for the 4080 SUPER, versus 1x HDMI 2.1b and 3x DisplayPort 2.1b for the 5080 SUPER. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Power characteristics differ considerably: the 4080 SUPER has a TDP of 320 W with a suggested PSU of 700 W, while the 5080 SUPER has a TDP of 415 W and no suggested PSU listed in the database. Physical dimensions also differ: the 4080 SUPER is a triple-slot card measuring 310 mm long, 140 mm high, and 61 mm wide, while the 5080 SUPER is a dual-slot card measuring 304 mm long, 137 mm high, and 40 mm wide. Both use a single 16-pin power connector.

The Verdict

The data clearly favors the RTX 4080 SUPER in the one benchmark where both have recorded scores. Its 6600 score in 3DMark Steel Nomad DX12 is 114.6% higher than the 5080 SUPER's 3075. The 4080 SUPER also has a far stronger overall standing in the database, with an average benchmark score of 54209 and an 86th percentile rank, compared to the 5080 SUPER's 3075 average and 19th percentile. The 5080 SUPER's nearest rivals include much older and lower-performance cards like the GeForce GTX 860M, which suggests that its recorded performance is not representative of a high-end modern GPU.

However, the 5080 SUPER does have clear specification advantages that the benchmark data does not capture. It has 24 GB of GDDR7 memory versus 16 GB of GDDR6X, higher memory bandwidth at 1.02 TB/s versus 736.3 GB/s, more shading units, TMUs, RT cores, and tensor cores, and a higher boost clock. It also uses PCIe 5.0, supports DisplayPort 2.1b, and has a lower slot width at dual-slot versus triple-slot, making it easier to fit in compact cases. The 5080 SUPER is listed as Active in production status, while the 4080 SUPER is End-of-life, and the 5080 SUPER has a newer release date.

The launch MSRP for both cards is 999 USD.

Given the data, the RTX 4080 SUPER is the pick for anyone relying on measured benchmark performance, particularly in DX12 workloads. The RTX 5080 SUPER is the pick for those who need more memory capacity and bandwidth, newer display outputs, and a smaller physical footprint, but its recorded benchmark score is far below the 4080 SUPER. The 5080 SUPER may be a newer product, but the only direct measurement available shows a massive performance deficit.

Where Each One Wins

The RTX 4080 SUPER wins decisively in the recorded benchmark. Its 3DMark Steel Nomad DX12 score of 6600 is more than double the 5080 SUPER's 3075, and its average benchmark score of 54209 places it in the 86th percentile of all GPUs. It also has a lower TDP at 320 W versus 415 W, which means lower power draw under load. Its nearest rivals are all high-performance cards, including the RTX 4080 at a 0.1% delta and the AMD Radeon 8060S at a 2.8% delta, showing that it competes in the upper tier of the database.

The RTX 5080 SUPER wins on specifications, not measured performance. It provides 24 GB of memory versus 16 GB, which matters for workloads that require large datasets or high-resolution textures. Its memory bandwidth of 1.02 TB/s is substantially higher than 736.3 GB/s, and its boost clock is higher at 2617 MHz versus 2550 MHz. It has more shading units, TMUs, RT cores, and tensor cores, and it uses PCIe 5.0 rather than PCIe 4.0. Its display outputs are newer, with HDMI 2.1b and DisplayPort 2.1b, and it is a dual-slot card at 304 mm length, which is shorter and thinner than the triple-slot 4080 SUPER at 310 mm. The 5080 SUPER is also listed as Active production, whereas the 4080 SUPER is End-of-life.
