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

The Verdict

The NVIDIA TITAN V CEO Edition and the NVIDIA GeForce GTX 650 Ti are separated by nearly six years of GPU architecture evolution, and the benchmark data reflects that chasm. The TITAN V CEO Edition is the overwhelming performance leader, with an average benchmark score of 9037 compared to the GTX 650 Ti's 8053. In PassMark G3D testing, the TITAN V CEO Edition scores 16988, while the GTX 650 Ti does not have a recorded PassMark G3D score in the database. The TITAN V CEO Edition also sits at the 45th percentile among all GPUs, while the GTX 650 Ti sits at the 42nd percentile.

The GTX 650 Ti is the card for systems with modest power delivery and physical space constraints. It is a single-slot card with a 110 W TDP, requiring only a single 6-pin power connector and a 300 W suggested power supply. Its 145 mm length (5.7 inches) makes it suitable for compact builds. The TITAN V CEO Edition, by contrast, is a dual-slot card with a 250 W TDP, requiring a 6-pin plus an 8-pin power connector and a 600 W suggested power supply. Its length extends to 267 mm (10.5 inches).

For users who need massive memory capacity and compute throughput, the TITAN V CEO Edition is the only choice. Its 32 GB of HBM2 memory dwarfs the GTX 650 Ti's 1 GB of GDDR5. The TITAN V CEO Edition also brings tensor cores and a 2:1 FP16 ratio, features entirely absent from the GTX 650 Ti. The GTX 650 Ti is strictly a legacy part for basic 3D acceleration, while the TITAN V CEO Edition is a compute-oriented flagship.

Architecture Differences

The TITAN V CEO Edition is built on the Volta architecture with the GV100 chip, fabricated on a 12 nm process at TSMC. It packs 21,100 million transistors into an 815 mm² die, yielding a transistor density of 25.9 million per square millimeter. The GTX 650 Ti uses the Kepler architecture with the GK106S chip, built on a 28 nm process, also at TSMC. It contains 2,540 million transistors on a 221 mm² die, with a density of 11.5 million per square millimeter.

The TITAN V CEO Edition features 5120 shading units, 320 texture mapping units, and 128 ROPs. It also includes 640 tensor cores, which are dedicated to deep learning and AI workloads. The GTX 650 Ti has 768 shading units, 64 TMUs, and 16 ROPs, with no tensor cores. The TITAN V CEO Edition's pixel rate is 186.2 GPixel/s and its texture rate is 465.6 GTexel/s, compared to 14.85 GPixel/s and 59.39 GTexel/s for the GTX 650 Ti.

Memory architecture differs fundamentally. The TITAN V CEO Edition uses 32 GB of HBM2 across a 4096-bit bus, delivering 868.4 GB/s of bandwidth. The GTX 650 Ti uses 1 GB of GDDR5 on a 128-bit bus, with 86.40 GB/s of bandwidth. The memory clock on the TITAN V CEO Edition is 848 MHz (1696 Mbps effective), while the GTX 650 Ti runs at 1350 MHz (5.4 Gbps effective).

API support also diverges. The TITAN V CEO Edition supports DirectX 12 (12_1) and Vulkan 1.4, while the GTX 650 Ti supports DirectX 12 (11_0) and Vulkan 1.2.175. Both support OpenGL 4.6. The TITAN V CEO Edition outputs via 1x HDMI 2.0 and 3x DisplayPort 1.4a, while the GTX 650 Ti offers 2x DVI and 1x mini-HDMI 1.4a.

Head-to-Head Benchmarks

The database does not contain direct head-to-head benchmark comparisons between the TITAN V CEO Edition and the GTX 650 Ti. However, the standalone benchmark results provide a clear picture of relative performance.

In PassMark G3D, the TITAN V CEO Edition scores 16988. The GTX 650 Ti has no PassMark G3D score recorded, but its average benchmark score of 8053 places it well below the TITAN V CEO Edition's average of 9037. The TITAN V CEO Edition's PassMark G2D score is 1086, while the GTX 650 Ti has no recorded G2D score.

The GTX 650 Ti does have Geekbench results: an OpenCL score of 7877 and a Vulkan score of 8229. The TITAN V CEO Edition has no Geekbench records in the database. This means the only directly comparable aggregate metric is the average benchmark score, where the TITAN V CEO Edition leads by 984 points, or roughly 12% over the GTX 650 Ti.

Looking at nearest rivals for context: the TITAN V CEO Edition's closest competitors include the GTX 660 (average score 9022, delta 0.2%), the GTX 560 (9058, delta -0.2%), and the AMD Radeon 890M (9210, delta -1.9%). Its average score is effectively on par with those cards. The GTX 650 Ti's nearest rivals include the GTX 880M (8040, delta 0.2%), the GTX 650 Ti Boost (8067, delta -0.2%), and the Quadro P5000 (8039, delta 0.2%). The GTX 650 Ti sits within a narrow band of those results.

The TITAN V CEO Edition's FP32 compute is 14.90 TFLOPS, while the GTX 650 Ti manages 1,425.4 GFLOPS (approximately 1.43 TFLOPS). That is a 10.4x advantage for the TITAN V CEO Edition in raw single-precision throughput. The TITAN V CEO Edition also delivers FP16 at 29.80 TFLOPS, which the GTX 650 Ti cannot match at all, as it has no FP16 capability recorded.
