Architecture Differences

The two cards belong to entirely different architectural generations. The GTX 650 Ti uses the GK106S chip built on Kepler architecture, fabricated on a 28 nm process at TSMC. The T600 uses the TU117 chip based on Turing architecture, also fabricated at TSMC but on a 12 nm process. This process shrink allows the T600 to pack 4,700 million transistors into a 200 mm² die, while the GTX 650 Ti contains 2,540 million transistors on a larger 221 mm² die. The transistor density tells the story: the T600 reaches 23.5M transistors per mm², while the GTX 650 Ti manages only 11.5M per mm².

The compute layout differs significantly. The GTX 650 Ti has 768 shading units, 64 texture mapping units, and 16 ROPs. The T600 has fewer shading units at 640, but doubles the ROP count to 32, while reducing TMUs to 40. Neither card includes ray tracing cores or tensor cores, so both rely on traditional rasterization and compute paths.

Memory technology also marks a generational divide. The GTX 650 Ti uses 1 GB of GDDR5 at 1350 MHz (5.4 Gbps effective), while the T600 uses 4 GB of GDDR6 at 1250 MHz (10 Gbps effective). Both use a 128-bit memory bus, but the newer memory standard gives the T600 nearly double the bandwidth. The T600 also benefits from a higher boost clock of 1335 MHz (with a 735 MHz base), while the GTX 650 Ti has no recorded base or boost clock in the database, only its memory clock.

API support reflects the architectural age. The GTX 650 Ti supports DirectX 12 (11_0), which is a partial implementation, while the T600 supports full DirectX 12 (12_1). Both cards support OpenGL 4.6, but the T600’s Vulkan support is newer at version 1.4, compared to 1.2.175 on the GTX 650 Ti.

Head-to-Head Benchmarks

The database records two direct benchmark comparisons between these cards, and the T600 wins both. In Geekbench OpenCL, the T600 scores 27875 against the GTX 650 Ti’s 7877, a delta of 71.7% in favor of the T600. This is a massive margin, indicating that the T600’s architecture handles compute workloads far more efficiently. The GTX 650 Ti’s Kepler design, with its older scheduling and memory subsystem, cannot match the Turing-based T600 in raw parallel compute.

In Geekbench Vulkan, the T600 again dominates with a score of 25580 versus 8229 for the GTX 650 Ti, a delta of 67.8%. The Vulkan result is slightly closer than OpenCL, but still shows the T600 at roughly three times the performance. The GTX 650 Ti’s older Vulkan driver implementation (1.2.175) likely contributes to this gap, as does the lower memory bandwidth and smaller frame buffer.

The GTX 650 Ti does have one advantage in the aggregate data: its average benchmark score of 8053 is higher than the T600’s 7035. This is because the GTX 650 Ti has only two benchmark entries (Geekbench OpenCL and Vulkan), both of which are in the 7800-8300 range. The T600 has nine benchmark entries, including several Passmark tests that score very low (for example, Passmark DirectX 12 at 25 and Passmark DirectX 10 at 32). These low scores drag down the T600’s average, even though its Geekbench scores are far superior. The T600’s Passmark G3D score of 6479 and GPU compute score of 2402 are more representative of its real-world capabilities, but they are still below the GTX 650 Ti’s Geekbench numbers.

The T600’s wins in both head-to-head tests give it a 2-0 record in the database. The GTX 650 Ti records zero direct wins. However, the GTX 650 Ti’s percentile ranking (42nd) is slightly higher than the T600’s (39th), which reflects the different benchmark distributions rather than actual performance parity.

Specification Differences

The two cards differ in nearly every measurable specification. The process node drops from 28 nm to 12 nm, and transistor count rises from 2,540 million to 4,700 million. Die size shrinks slightly from 221 mm² to 200 mm², while transistor density doubles from 11.5M to 23.5M per mm².

Memory capacity quadruples from 1 GB to 4 GB, and the type changes from GDDR5 to GDDR6. Effective memory speed rises from 5.4 Gbps to 10 Gbps, and bandwidth increases from 86.40 GB/s to 160.0 GB/s. The bus width remains 128 bit on both cards.

Compute resources shift as well. Shading units drop from 768 to 640, TMUs drop from 64 to 40, but ROPs double from 16 to 32. The pixel rate jumps from 14.85 GPixel/s to 42.72 GPixel/s, while the texture rate falls from 59.39 GTexel/s to 53.40 GTexel/s. FP32 throughput rises from 1,425.4 GFLOPS to 1.709 TFLOPS, and the T600 adds FP16 capability at 3.418 TFLOPS (2:1), which the GTX 650 Ti lacks entirely.

Power consumption drops dramatically. The TDP falls from 110 W to 40 W, the power connector requirement disappears (the GTX 650 Ti needs a 6-pin connector, the T600 needs none), and the suggested PSU drops from 300 W to 200 W. Both cards are single-slot, but the GTX 650 Ti measures 145 mm (5.7 inches) in length, while the T600 has no recorded dimensions.

Display outputs change completely. The GTX 650 Ti offers 2x DVI and 1x mini-HDMI 1.4a, while the T600 offers 4x mini-DisplayPort 1.4a. The GTX 650 Ti was released on October 8, 2012, with a launch MSRP of 149 USD; the T600 was released on April 11, 2021, with no recorded launch MSRP. Both cards are end-of-life, and both use PCIe 3.0 x16 interfaces.

Where Each One Wins

The T600 wins decisively in compute-heavy workloads. Its Geekbench OpenCL score of 27875 is 71.7% higher than the GTX 650 Ti’s, and its Geekbench Vulkan score of 25580 is 67.8% higher. This makes the T600 the clear choice for any application that leverages OpenCL or Vulkan for general-purpose GPU computing, such as rendering, video encoding, or scientific simulation. The T600’s 4 GB of VRAM also allows larger datasets to reside in memory, while the GTX 650 Ti’s 1 GB limit will force frequent transfers over the PCIe bus.

The T600 also wins on power efficiency. Its 40 W TDP is less than half the GTX 650 Ti’s 110 W, and it requires no external power connector. This makes it suitable for compact systems with small power supplies, and its 4x mini-DisplayPort outputs support multi-monitor professional setups. The T600’s higher pixel rate (42.72 GPixel/s) and doubled ROP count (32 vs 16) give it an edge in fill-rate-bound scenarios, such as high-resolution 2D compositing or multiple display outputs.

The GTX 650 Ti wins in the aggregate benchmark average. Its 8053 average score exceeds the T600’s 7035, and its percentile rank is 42nd versus 39th. This is partly a statistical artifact of the T600’s low Passmark scores, but it also indicates that the GTX 650 Ti has more consistent performance across the tests recorded in the database. The GTX 650 Ti’s higher texture rate (59.39 GTexel/s vs 53.40 GTexel/s) suggests it may hold up better in texture-bound legacy games, though no direct gaming benchmarks are recorded.

The GTX 650 Ti also has a longer physical presence (145 mm) and a simpler display output set (DVI and HDMI), which may be more compatible with older monitors or capture equipment. Its launch MSRP of 149 USD was modest for its era, though the database does not record the T600’s price.

The Verdict

Choose the NVIDIA T600 if your priority is raw compute performance. The data shows it outperforms the GTX 650 Ti by 71.7% in OpenCL and 67.8% in Vulkan, making it the only sensible option for GPU compute tasks. Its 4 GB memory capacity, 160.0 GB/s bandwidth, and 40 W power draw make it a far more capable and efficient professional card. The T600 also supports newer APIs, including DirectX 12 (12_1) and Vulkan 1.4, which future-proof it for modern software.

Choose the NVIDIA GeForce GTX 650 Ti if you rely on the database’s aggregate scores or need compatibility with legacy display outputs. Its average benchmark score of 8053 is higher than the T600’s 7035, and its 42nd percentile ranking is above the T600’s 39th. The GTX 650 Ti’s higher texture rate and DVI outputs may serve older systems or specific testing environments better. However, its 1 GB memory, 86.40 GB/s bandwidth, and 110 W TDP are significant drawbacks.

The verdict is clear for most users: the T600 is the superior card in every head-to-head test recorded, and its architectural advantages in memory, power, and API support reinforce that conclusion. The GTX 650 Ti’s only wins are statistical, derived from the absence of low-scoring Passmark tests in its benchmark set. When actual comparative benchmarks exist, the T600 dominates. The GTX 650 Ti remains a historical curiosity, but the T600 is the functional choice for any modern workload that leverages compute APIs.
