NVIDIA GeForce RTX 4080 vs NVIDIA TITAN X Pascal Comparison

The Verdict

The data is unambiguous. The NVIDIA GeForce RTX 4080 is the superior card in every recorded benchmark, and the performance gap is enormous. In the two head-to-head tests available, the RTX 4080 wins both, with margins of 68.9% and 70.6% over the TITAN X Pascal. The TITAN X Pascal is a legacy product, end-of-life, and its architecture is two generations old. The RTX 4080 should be the choice for anyone building a modern system with current software and API requirements.

However, the TITAN X Pascal is not without a niche. Its average benchmark score of 72,098 places it at the 91st percentile of all GPUs in the database, which is actually higher than the RTX 4080's 86th percentile. This is because the TITAN X Pascal's recorded scores come from only two tests (Geekbench OpenCL and Vulkan), while the RTX 4080's average is dragged down by a broader set of tests including older DirectX 9, 10, and 11 benchmarks where it scores relatively low. The TITAN X Pascal's nearest rival, the AMD Radeon Vega Frontier Edition, sits only 1.7% ahead, and the AMD Radeon Pro Vega 64 is a mere 0.4% ahead. In contrast, the RTX 4080 is nearly identical in average score to its closest rival, the RTX 4080 SUPER, with a delta of only 0.1%.

For a user with a legacy workload that relies on OpenCL or Vulkan and does not need modern features like hardware ray tracing or tensor cores, the TITAN X Pascal can still be a capable performer. But for any current or future-oriented workload, the RTX 4080's raw compute power, as evidenced by its 214,739 Geekbench OpenCL score versus the TITAN X Pascal's 66,696, makes it the only rational choice. The RTX 4080 is triple-slot, requires a 700 W PSU, and uses a 16-pin connector, while the TITAN X Pascal is dual-slot with a 600 W PSU recommendation. Those are physical constraints, but the performance data justifies them.

Architecture Differences

The two cards represent completely different eras of NVIDIA design. The TITAN X Pascal uses the GP102 chip on a 16 nm TSMC process, packing 11,800 million transistors into a 471 mm² die. The RTX 4080 uses the AD103 chip on a 5 nm TSMC process, with 45,900 million transistors in a smaller 379 mm² die. This is a transistor density increase from 25.1M per mm² to 121.1M per mm², a fundamental shift in manufacturing capability.

The compute pipelines are drastically different. The TITAN X Pascal has 3,584 shading units, 224 texture mapping units, and 96 ROPs. The RTX 4080 has 9,728 shading units, 304 TMUs, and 112 ROPs. The RTX 4080 also introduces dedicated hardware that the TITAN X Pascal lacks entirely: 76 ray tracing cores and 304 tensor cores. This means the RTX 4080 supports DirectX 12 Ultimate (12_2), while the TITAN X Pascal is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4, but the RTX 4080's feature set for modern games and compute workloads is fundamentally more advanced.

Memory configurations also diverge. The TITAN X Pascal uses 12 GB of GDDR5X on a 384-bit bus, yielding 480.4 GB/s of bandwidth. The RTX 4080 uses 16 GB of GDDR6X on a 256-bit bus, yielding 716.8 GB/s. Despite the narrower bus, the RTX 4080's faster memory clock (22.4 Gbps effective versus 10 Gbps effective) delivers substantially more bandwidth.

Clock speeds tell a similar story of generational improvement. The TITAN X Pascal has a base clock of 1417 MHz and a boost of 1531 MHz. The RTX 4080 starts at 2205 MHz and boosts to 2505 MHz. The RTX 4080's FP32 throughput is 48.74 TFLOPS versus 10.97 TFLOPS for the TITAN X Pascal, and its FP16 performance is a full 48.74 TFLOPS (1:1 ratio) versus a paltry 171.5 GFLOPS (1:64 ratio) on the older card.

Where Each One Wins

The RTX 4080 wins in every direct benchmark comparison. In Geekbench OpenCL, it scores 214,739 versus 66,696, a 68.9% advantage. In Geekbench Vulkan, it scores 263,779 versus 77,499, a 70.6% advantage. The RTX 4080 is also the only card of the two with any recorded DirectX 9, 10, 11, or 12 benchmark scores, as well as Passmark G2D, G3D, and GPU Compute scores. The TITAN X Pascal has no data in those tests at all.

Where the TITAN X Pascal can claim a relative advantage is in its percentile ranking. Its 91st percentile versus the RTX 4080's 86th percentile reflects the fact that its average score of 72,098 is higher than the RTX 4080's 54,247. This is a statistical artifact of test selection, not a real performance win. The TITAN X Pascal's nearest rivals are all AMD cards with average scores within 1.8% of its own, indicating that it sits in a performance tier that is competitive with mid-range-to-high-end AMD products of its era. The RTX 4080's rivals are the RTX 4080 SUPER (0.1% ahead), the AMD Radeon Pro W5700X (1.1% behind), the AMD Radeon RX 6750 GRE 12 GB (2.6% behind), and the AMD Radeon 8060S (2.7% behind).

The practical split is clear. The RTX 4080 is for modern gaming, ray tracing, AI workloads (thanks to tensor cores), and high-resolution content creation. The TITAN X Pascal is for legacy compute tasks that are specifically optimized for OpenCL or Vulkan and do not benefit from newer hardware features. A user running an older Linux compute server with only Vulkan support might still find the TITAN X Pascal adequate, but the RTX 4080 would crush it in the same workload.

Head-to-Head Benchmarks

The recorded data contains only two direct head-to-head tests, and the RTX 4080 dominates both. In Geekbench OpenCL, the RTX 4080's score of 214,739 is 68.9% better than the TITAN X Pascal's 66,696. This is not a marginal improvement; it is a complete generational leap. The TITAN X Pascal's 10.97 TFLOPS FP32 throughput is simply outclassed by the RTX 4080's 48.74 TFLOPS.

In Geekbench Vulkan, the gap is even wider. The RTX 4080 scores 263,779, while the TITAN X Pascal manages 77,499, a 70.6% deficit. This test likely benefits from the RTX 4080's much higher shading unit count (9,728 versus 3,584) and its faster boost clock (2505 MHz versus 1531 MHz). The TITAN X Pascal's Vulkan implementation, while present (version 1.4), cannot compensate for the raw hardware advantage of the newer card.

Beyond these two tests, the RTX 4080 has additional recorded scores that the TITAN X Pascal simply does not have. These include Passmark DirectX 10 (204), DirectX 11 (314), DirectX 12 (132), DirectX 9 (370), G2D (1239), G3D (34457), and GPU Compute (20671). The TITAN X Pascal has no data in any of these categories, meaning the RTX 4080 is the only option for workloads that rely on those specific APIs.

The RTX 4080's nearest rival, the RTX 4080 SUPER, has an average score of 54,209, which is only 0.1% higher than the RTX 4080's 54,247. This indicates that the RTX 4080 is essentially at the top of its performance tier, with no meaningful gap to its immediate successor. The TITAN X Pascal, on the other hand, is slightly below the AMD Radeon Vega Frontier Edition (73,370, a 1.7% difference) and just above the AMD Radeon RX 6600 LE (70,829, a 1.8% difference). The TITAN X Pascal's performance bracket is crowded, while the RTX 4080's is not.

Specification Differences

The two cards differ in nearly every specification field. The RTX 4080 uses a 5 nm process node from TSMC, while the TITAN X Pascal uses 16 nm. Transistor counts are 45,900 million versus 11,800 million. Die size is 379 mm² for the RTX 4080 and 471 mm² for the TITAN X Pascal. Transistor density is 121.1M per mm² versus 25.1M per mm².

The RTX 4080 has more of everything: 9,728 shading units versus 3,584, 304 TMUs versus 224, and 112 ROPs versus 96. It also has 76 ray tracing cores and 304 tensor cores, while the TITAN X Pascal has none. Pixel rate is 280.6 GPixel/s versus 147.0 GPixel/s. Texture rate is 761.5 GTexel/s versus 342.9 GTexel/s. FP32 is 48.74 TFLOPS versus 10.97 TFLOPS. FP16 is 48.74 TFLOPS versus 171.5 GFLOPS.

Memory differs in size (16 GB versus 12 GB), type (GDDR6X versus GDDR5X), bus width (256-bit versus 384-bit), and bandwidth (716.8 GB/s versus 480.4 GB/s). The RTX 4080's memory clock is 1400 MHz with 22.4 Gbps effective, while the TITAN X Pascal's is 1251 MHz with 10 Gbps effective.

Power requirements differ: the RTX 4080 has a 320 W TDP with a 700 W suggested PSU and a single 16-pin connector, while the TITAN X Pascal has a 250 W TDP with a 600 W suggested PSU and 1x 6-pin + 1x 8-pin connectors. The RTX 4080 is triple-slot and larger (310 mm length, 140 mm height, 61 mm width), while the TITAN X Pascal is dual-slot and smaller (267 mm length, 112 mm height, 40 mm width). The RTX 4080 uses PCIe 4.0 x16, while the TITAN X Pascal uses PCIe 3.0 x16.
