NVIDIA GeForce GTX 650 Ti Boost vs NVIDIA TITAN V CEO Edition Comparison

Head-to-Head Benchmarks

The benchmark data reveals a stark generational divide between these two NVIDIA cards. The TITAN V CEO Edition records a Passmark G3D score of 16,988, while the GTX 650 Ti Boost does not have a comparable G3D entry in the database. However, the GTX 650 Ti Boost has a Passmark G2D score of 1,086, whereas the TITAN V CEO Edition posts a lower 1,086 in that same test? No, the pack shows the TITAN V CEO Edition at 1,086 for G2D, identical to the GTX 650 Ti Boost. The real separation comes from average benchmark scores: the TITAN V CEO Edition averages 9,037, placing it in the 45th percentile of all GPUs, while the GTX 650 Ti Boost averages 8,067, sitting in the 42nd percentile.

Looking at the nearest rivals for each card clarifies their standing. The TITAN V CEO Edition’s average score of 9,037 puts it a marginal 0.2% ahead of the GeForce GTX 660 (9,022) and 1.3% ahead of the AMD Radeon 550X (8,918). It trails the AMD Radeon 890M (9,210) by 1.9% and the GeForce GTX 560 (9,058) by 0.2%. These are incredibly tight margins, suggesting the TITAN V CEO Edition’s average benchmark score is not dominant in its immediate peer group, despite its enormous specifications.

The GTX 650 Ti Boost, by contrast, shows its own tight clustering. Its 8,067 average is 0.2% behind the NVIDIA GRID K2 (8,080), 0.2% ahead of the GeForce GTX 650 Ti (8,053), and 0.3% ahead of both the GeForce GTX 880M (8,040) and the Quadro P5000 (8,039). The data indicates that the GTX 650 Ti Boost is a mid-pack performer in its own era, while the TITAN V CEO Edition, despite its advanced architecture, appears benchmarked against a different class of rivals entirely.

There are no direct head-to-head benchmark entries shared between these two cards in the database. The wins tally shows zero for each side in the headToHeadBenchmarks array. The only overlapping metric is the Passmark G2D score, which is identical at 1,086. In the absence of shared workloads, the average benchmark score becomes the primary differentiator: the TITAN V CEO Edition leads by 12.0% (calculated from 9,037 versus 8,067), a substantial gap that reflects its more recent release and far larger hardware budget.

Architecture Differences

The TITAN V CEO Edition is built on the GV100 chip using the Volta architecture, fabricated on a 12 nm process at TSMC. It integrates 21,100 million transistors on a die size of 815 mm², yielding a transistor density of 25.9 million per mm². The GTX 650 Ti Boost uses the GK106 chip with the Kepler architecture, also from TSMC, but on a 28 nm node. Its transistor count is 2,540 million on a 221 mm² die, giving a density of 11.5 million per mm². The TITAN V CEO Edition therefore packs over eight times the transistors into roughly 3.7 times the die area.

Memory subsystems are completely different. The TITAN V CEO Edition features 32 GB of HBM2 with a 4096-bit bus and 868.4 GB/s of bandwidth. The GTX 650 Ti Boost has 2 GB of GDDR5 on a 192-bit bus, delivering 144.2 GB/s. That is a 6x difference in capacity and a 6x difference in bandwidth, which directly impacts texture-heavy and high-resolution workloads.

Compute resources diverge sharply. The TITAN V CEO Edition has 5,120 shading units, 320 TMUs, and 128 ROPs, plus 640 tensor cores. The GTX 650 Ti Boost has 768 shading units, 64 TMUs, and 24 ROPs, with no tensor cores. The TITAN V CEO Edition’s FP32 throughput is 14.90 TFLOPS versus 1.585 TFLOPS for the GTX 650 Ti Boost, a 9.4x advantage. The TITAN V CEO Edition also supports FP16 at 29.80 TFLOPS (2:1 ratio); the GTX 650 Ti Boost has no FP16 entry.

Clock speeds show the TITAN V CEO Edition running at 1200 MHz base and 1455 MHz boost, while the GTX 650 Ti Boost runs at 980 MHz base and 1032 MHz boost. The memory clocks are 848 MHz (1696 Mbps effective) for the TITAN V CEO Edition and 1502 MHz (6 Gbps effective) for the GTX 650 Ti Boost. The pixel rate is 186.2 GPixel/s for the TITAN V CEO Edition versus 16.51 GPixel/s for the GTX 650 Ti Boost, and the texture rate is 465.6 GTexel/s versus 66.05 GTexel/s.

API support differs in DirectX version: the TITAN V CEO Edition supports DirectX 12 (12_1), while the GTX 650 Ti Boost supports DirectX 12 (11_0). Both support OpenGL 4.6, but Vulkan support is 1.4 on the TITAN V CEO Edition and 1.2.175 on the GTX 650 Ti Boost.

Where Each One Wins

The TITAN V CEO Edition wins decisively in any compute-heavy scenario. Its 14.90 TFLOPS FP32 performance, 640 tensor cores, and 868.4 GB/s memory bandwidth make it suited for machine learning inference, scientific simulation, and high-resolution texture streaming. The 32 GB HBM2 frame buffer is far beyond what the GTX 650 Ti Boost’s 2 GB GDDR5 can address, so large datasets or multi-monitor 4K compositing favor the TITAN V CEO Edition overwhelmingly.

The GTX 650 Ti Boost wins in the narrow category of legacy compatibility and low-power operation. Its 134 W TDP is roughly half of the TITAN V CEO Edition’s 250 W, and its single 6-pin power connector is simpler than the TITAN V CEO Edition’s 1x 6-pin plus 1x 8-pin arrangement. The GTX 650 Ti Boost’s 300 W suggested PSU is half of the TITAN V CEO Edition’s 600 W recommendation. For a small form-factor build or a system with an older power supply, the GTX 650 Ti Boost is the practical choice.

In raw rasterization, the TITAN V CEO Edition’s 186.2 GPixel/s fill rate versus 16.51 GPixel/s for the GTX 650 Ti Boost means the former handles high-resolution anti-aliasing and multi-sample rendering without strain. The GTX 650 Ti Boost’s 66.05 GTexel/s texture rate is adequate for 1080p-era titles, but the TITAN V CEO Edition’s 465.6 GTexel/s is in a different league for modern texture-heavy scenes.

The GTX 650 Ti Boost has Geekbench entries for Metal (4,858), OpenCL (9,302), and Vulkan (10,041), while the TITAN V CEO Edition has no Geekbench scores in the pack. That suggests the GTX 650 Ti Boost may be more thoroughly tested in cross-platform API benchmarks, but the TITAN V CEO Edition’s Passmark G3D score of 16,988 (if we consider it as a proxy for 3D performance) dwarfs anything the GTX 650 Ti Boost could produce in the same class.
