NVIDIA GeForce RTX 4080 SUPER vs NVIDIA TITAN X Pascal Comparison

The NVIDIA TITAN X Pascal and the NVIDIA GeForce RTX 4080 SUPER represent two very different eras of GPU design. The data recorded in the database shows a clear generational shift: the RTX 4080 SUPER wins both head-to-head benchmark comparisons by a margin of over 69%, while the TITAN X Pascal relies on its older architecture and a different set of specifications. This analysis breaks down the recorded measurements to determine which card suits which workload, based strictly on the available data.

The Verdict

The benchmark results are unambiguous. The RTX 4080 SUPER dominates the TITAN X Pascal in every recorded head-to-head comparison. In the Geekbench OpenCL test, the RTX 4080 SUPER scores 219,065 against the TITAN X Pascal’s 66,696, a difference of 69.6%. In the Geekbench Vulkan test, the RTX 4080 SUPER scores 260,075 versus 77,499, a difference of 70.2%. If the primary goal is maximum raw compute performance in modern APIs, the RTX 4080 SUPER is the only logical choice from this data.

However, the TITAN X Pascal still holds a notable position in the database. Its average benchmark score is 72,098, which places it in the 91st percentile of all GPUs. This is higher than the RTX 4080 SUPER’s 86th percentile ranking. The TITAN X Pascal’s average score of 72,098 is significantly higher than its head-to-head scores, suggesting that it performs relatively better in other tests not shared with the RTX 4080 SUPER. For users running legacy applications or specific workloads that favor its architecture, the TITAN X Pascal may still be a relevant card, but the recorded head-to-head data does not support it over the newer model.

The RTX 4080 SUPER also shows a more consistent performance profile across a wider range of tests in the database. Its Passmark G3D score is 34,245, and its Passmark GPU Compute score is 19,822. The TITAN X Pascal has no recorded Passmark scores, so its performance in those specific DirectX and compute tests cannot be compared. The verdict is clear: for any workload covered by the shared benchmarks, the RTX 4080 SUPER wins decisively. The TITAN X Pascal remains a high-percentile card for general GPU performance, but it is not competitive with the RTX 4080 SUPER in the tests that matter most.

Architecture Differences

The two cards are built on entirely different architectures. The TITAN X Pascal uses the Pascal architecture with the GP102 chip, manufactured on a 16 nm process at TSMC. The RTX 4080 SUPER uses the Ada Lovelace architecture with the AD103 chip, manufactured on a 5 nm process, also at TSMC. This process node difference is substantial: the RTX 4080 SUPER packs 45,900 million transistors into a 379 mm² die, while the TITAN X Pascal contains 11,800 million transistors on a larger 471 mm² die. The transistor density tells the story: the RTX 4080 SUPER has 121.1 million transistors per square millimeter, compared to the TITAN X Pascal’s 25.1 million per square millimeter.

The RTX 4080 SUPER also introduces hardware features that the TITAN X Pascal simply does not have. It includes 80 ray tracing cores and 320 tensor cores, while the TITAN X Pascal has none of either. The TITAN X Pascal’s FP16 performance is severely limited at 171.5 GFLOPS with a 1:64 ratio, meaning it processes FP16 at a fraction of its FP32 rate. The RTX 4080 SUPER delivers 52.22 TFLOPS of FP16 with a 1:1 ratio, making it fully capable of fast half-precision work. The RTX 4080 SUPER also supports DirectX 12 Ultimate (12_2), while the TITAN X Pascal is limited to DirectX 12 (12_1).

The memory subsystems are equally different. The TITAN X Pascal uses 12 GB of GDDR5X on a 384-bit bus, yielding 480.4 GB/s of bandwidth. The RTX 4080 SUPER uses 16 GB of GDDR6X on a 256-bit bus, but achieves 736.3 GB/s of bandwidth due to faster memory clocks. The RTX 4080 SUPER’s memory runs at 1438 MHz with 23 Gbps effective speed, while the TITAN X Pascal’s memory runs at 1251 MHz with 10 Gbps effective speed. The newer card also uses a PCIe 4.0 x16 interface, while the TITAN X Pascal uses PCIe 3.0 x16.

Where Each One Wins

The RTX 4080 SUPER wins every recorded head-to-head benchmark. In OpenCL, it is 69.6% faster than the TITAN X Pascal. In Vulkan, it is 70.2% faster. These are not marginal wins; they represent a massive generational leap. The RTX 4080 SUPER’s raw FP32 performance is 52.22 TFLOPS versus the TITAN X Pascal’s 10.97 TFLOPS, and its texture rate is 816.0 GTexel/s versus 342.9 GTexel/s. For modern gaming, ray tracing workloads, and compute-heavy applications, the RTX 4080 SUPER is the clear winner.

The TITAN X Pascal’s wins are less about performance and more about compatibility and physical characteristics. It is a dual-slot card with a length of 267 mm, a height of 112 mm, and a width of 40 mm. The RTX 4080 SUPER is a triple-slot card measuring 310 mm in length, 140 mm in height, and 61 mm in width. The TITAN X Pascal uses a 1x 6-pin plus 1x 8-pin power connector setup, while the RTX 4080 SUPER uses a single 16-pin connector. The TITAN X Pascal has a lower TDP of 250 W versus the RTX 4080 SUPER’s 320 W, and it requires a 600 W PSU versus the RTX 4080 SUPER’s 700 W suggestion.

The TITAN X Pascal also offers a DVI output, which the RTX 4080 SUPER lacks. The RTX 4080 SUPER has one HDMI 2.1 output and three DisplayPort 1.4a outputs, while the TITAN X Pascal has one DVI, one HDMI 2.0, and three DisplayPort 1.4a outputs. For users with legacy DVI monitors, the TITAN X Pascal has an advantage. For users needing HDMI 2.1 for high refresh rate 4K displays, the RTX 4080 SUPER is the better option.
