NVIDIA GeForce GTX 780 Ti vs NVIDIA Quadro RTX 8000 Comparison

The Verdict

The NVIDIA Quadro RTX 8000 is the decisive winner in every recorded head-to-head benchmark, and the performance gap is enormous, not incremental. In Geekbench OpenCL, the RTX 8000 scores 101,883 against 27,326 for the GTX 780 Ti, a 272.8% advantage. In Geekbench Vulkan, the RTX 8000 posts 122,637 versus 27,238, a 350.2% lead. The RTX 8000 wins both recorded head-to-head tests, while the GTX 780 Ti wins none.

The RTX 8000 also carries the newer architecture, the larger memory pool, and the higher feature set. It sits at the 74th percentile of all GPUs in the database, with an average benchmark score of 28,421. The GTX 780 Ti sits at the 70th percentile with an average benchmark score of 24,236. That percentile gap is modest, but the head-to-head deltas are not. The RTX 8000 is the pick for anyone prioritizing raw compute throughput, modern API support, and massive frame buffer capacity. The GTX 780 Ti is the pick only for a system that specifically needs a Kepler-era card, which is a niche requirement. The data does not support choosing the GTX 780 Ti on performance grounds.

Architecture Differences

The RTX 8000 is built on the Turing architecture using the TU102 chip, fabricated on a 12 nm process at TSMC. It packs 18,600 million transistors into a 754 mm² die, with a transistor density of 24.7 million per mm². The GTX 780 Ti uses the older Kepler architecture with the GK110B chip, also from TSMC but on a 28 nm process, and contains 7,080 million transistors on a 561 mm² die, giving it a density of 12.6 million per mm². The RTX 8000 therefore has roughly 2.6 times the transistor count and a much higher density, which reflects the process-node advantage.

The RTX 8000 includes 72 RT cores and 576 tensor cores, features that are entirely absent from the GTX 780 Ti, which lists no RT or tensor core counts. This makes the RTX 8000 a hardware ray-tracing and AI-acceleration capable card, while the GTX 780 Ti has no such dedicated units. The RTX 8000 also supports DirectX 12 Ultimate (12_2), while the GTX 780 Ti is limited to DirectX 12 (11_1). Vulkan support differs as well: the RTX 8000 lists Vulkan 1.4, while the GTX 780 Ti lists Vulkan 1.2.175. Both cards support OpenGL 4.6 and use the PCIe 3.0 x16 bus interface.

The RTX 8000 belongs to the Quadro Turing generation and is the successor to Quadro Volta, with Workstation Ampere as its successor. The GTX 780 Ti belongs to the GeForce 700 generation, with the GeForce 600 as its predecessor and the GeForce 900 as its successor. The RTX 8000 is also classified under the GeForce 80-series label in the database, which is a notable series assignment given its Quadro branding.

Specification Differences

The RTX 8000 has 4,608 shading units, 288 texture mapping units, and 96 ROPs. The GTX 780 Ti has 2,880 shading units, 240 TMUs, and 48 ROPs. The RTX 8000 nearly doubles the shader count and doubles the ROP count. Clock speeds differ substantially: the RTX 8000 runs at a base of 1395 MHz and a boost of 1770 MHz, while the GTX 780 Ti runs at 875 MHz base and 928 MHz boost. The RTX 8000's boost clock is 842 MHz higher.

Memory is a major differentiator. The RTX 8000 uses 48 GB of GDDR6 at 1750 MHz with 14 Gbps effective speed, delivering 672.0 GB/s of bandwidth across a 384-bit bus. The GTX 780 Ti uses 3 GB of GDDR5 at 1753 MHz with 7 Gbps effective speed, delivering 336.6 GB/s across the same 384-bit bus width. The RTX 8000 has 16 times the memory capacity and exactly double the bandwidth.

Pixel and texture rates follow the same pattern. The RTX 8000 achieves 169.9 GPixel/s and 509.8 GTexel/s, while the GTX 780 Ti achieves 55.68 GPixel/s and 222.7 GTexel/s. The FP32 compute figures are 16.31 TFLOPS for the RTX 8000 versus 5.345 TFLOPS for the GTX 780 Ti. The RTX 8000 also lists FP16 performance of 32.62 TFLOPS at a 2:1 ratio, while the GTX 780 Ti has no recorded FP16 figure.

Power and physical specs are similar in some respects. Both are dual-slot cards, both use a 1x 6-pin plus 1x 8-pin power connector configuration, both require a 600 W suggested PSU, and both are 267 mm long and 111 mm tall. The TDP is 260 W for the RTX 8000 and 250 W for the GTX 780 Ti, a difference of only 10 W. Display outputs differ: the RTX 8000 offers 4x DisplayPort 1.4a plus 1x USB Type-C, while the GTX 780 Ti offers 2x DVI, 1x HDMI 1.4a, and 1x DisplayPort 1.2. The GTX 780 Ti has a recorded width of 38 mm, while the RTX 8000 has no width listed.

Head-to-Head Benchmarks

The database records two head-to-head benchmark comparisons, and the RTX 8000 wins both. The first is Geekbench OpenCL, where the RTX 8000 scores 101,883 and the GTX 780 Ti scores 27,326. That is a 272.8% delta in favor of the RTX 8000. To put that in context, the RTX 8000's nearest rivals in the overall database include the AMD Radeon R9 M295X at 28,580 (a 0.6% gap in favor of the AMD card), the AMD Radeon RX 570 at 28,766 (1.2% ahead of the RTX 8000), the AMD FirePro S7150 at 28,117 (1.1% behind), and the NVIDIA GeForce GTX 980 Ti at 28,020 (1.4% behind). The RTX 8000 sits in a tight pack with those cards on average score, but its head-to-head OpenCL result against the GTX 780 Ti is far outside that range.

The second head-to-head test is Geekbench Vulkan, where the RTX 8000 scores 122,637 against 27,238 for the GTX 780 Ti, a 350.2% delta. This is the largest win in either direction across the recorded head-to-head data. The GTX 780 Ti's nearest rivals include the NVIDIA GeForce GTX 1630 at 24,277 (0.2% ahead of the GTX 780 Ti), the NVIDIA GeForce RTX 2080 SUPER at 24,170 (0.3% behind), the AMD Radeon RX 6800S at 24,063 (0.7% behind), and the AMD Radeon RX 6600 XT at 24,442 (0.8% ahead). The GTX 780 Ti's average benchmark score of 24,236 places it in that same range, but the head-to-head Vulkan result shows it trailing the RTX 8000 by more than a factor of four.

The RTX 8000 also has additional benchmark records that the GTX 780 Ti lacks. The RTX 8000 scores 137 in PassMark DirectX 10, 188 in DirectX 11, 79 in DirectX 12, 211 in DirectX 9, 866 in PassMark G2D, 19,799 in PassMark G3D, and 9,992 in PassMark GPU compute. The GTX 780 Ti has no PassMark entries in the database, only Geekbench Metal (18,144), Geekbench OpenCL, and Geekbench Vulkan. The RTX 8000 has no Geekbench Metal record.

The overall picture is one of generational dominance. The RTX 8000 wins both head-to-head tests with deltas of 272.8% and 350.2%, holds a 4,185-point advantage in average benchmark score (28,421 versus 24,236), and ranks four percentile points higher in the database. The GTX 780 Ti's only advantage is its 699 USD launch MSRP compared to the RTX 8000's 9,999 USD launch MSRP, but on measured performance, the RTX 8000 is in a different class entirely.
