NVIDIA GeForce GTX 650 Ti Boost vs NVIDIA GeForce GTX 970 Comparison

The Verdict

The benchmark data presents a clear hierarchical outcome: the NVIDIA GeForce GTX 970 is the decisive winner across every recorded head-to-head test, while the GTX 650 Ti Boost occupies a distinctly lower performance tier. In the three shared benchmarks, the GTX 970 leads by margins ranging from roughly 50% to 69%, which is not a close contest but rather a generational leap in capability. The GTX 650 Ti Boost, however, holds a notable advantage in average benchmark score within its own peer group, posting 8,067 versus the GTX 970's 7,157, though this reflects differences in the test suites each card was subjected to rather than direct comparability.

For a user choosing between these two, the GTX 970 is the obvious pick for any workload involving modern DirectX 12 titles, Vulkan applications, or compute-heavy tasks. Its scores in Geekbench Metal (13,595), OpenCL (29,982), and Vulkan (20,005) dwarf the GTX 650 Ti Boost's corresponding results (4,858, 9,302, and 10,041). The GTX 970 also offers double the memory (4 GB versus 2 GB) and a wider 256-bit bus, making it substantially better equipped for higher resolutions and larger textures. The GTX 650 Ti Boost, by contrast, is a card from an earlier generation that still delivers respectable numbers in legacy benchmarks, but its lower shading unit count (768 versus 1,664) and reduced texture and pixel rates place it firmly below the GTX 970 in any modern context.

That said, the GTX 650 Ti Boost is not without merit. Its average benchmark score of 8,067 places it above the GTX 970's 7,157, and its nearest rivals include the NVIDIA GRID K2, GTX 650 Ti, GTX 880M, and Quadro P5000, all within a 0.3% delta. This suggests that within the GTX 650 Ti Boost's performance class, it is a competitive part, edging out its immediate predecessor by 0.2% and matching the GRID K2 nearly exactly. The GTX 970, however, sits in a different bracket, with nearest rivals like the Intel Iris Pro Graphics P580, GeForce GTX 560 SE, Radeon Vega 8 Mobile, and GeForce GTX 750, all slightly below it in average score. This is a tale of two different performance strata, and the data leaves no ambiguity about which card dominates in raw throughput.

The verdict: choose the GTX 970 for any serious gaming, compute, or content creation workload where API support and memory capacity matter. Choose the GTX 650 Ti Boost only if you are constrained to legacy titles and prioritize its superior standing among its own contemporaries.

Where Each One Wins

The GTX 970 wins in every single head-to-head benchmark recorded in the database. In Geekbench Metal, it scores 13,595 against 4,858 for the GTX 650 Ti Boost, a delta of 64.3% in favor of the newer card. In Geekbench OpenCL, the margin grows to 69%, with scores of 29,982 and 9,302 respectively. Even in Geekbench Vulkan, where the gap is smallest, the GTX 970 still leads by 49.8%, posting 20,005 versus 10,041. These are not narrow victories; they represent a fundamental difference in compute and graphics capability.

The GTX 970 also wins on architectural features that translate to real-world performance. It supports DirectX 12 (12_1) and Vulkan 1.4, while the GTX 650 Ti Boost only manages DirectX 12 (11_0) and Vulkan 1.2.175. This means the GTX 970 is future-proofed for newer API features, whereas the GTX 650 Ti Boost is limited to older rendering paths. The GTX 970 also offers 4 GB of GDDR5 memory on a 256-bit bus with 224.4 GB/s bandwidth, versus 2 GB on a 192-bit bus with 144.2 GB/s for the GTX 650 Ti Boost. Higher memory capacity and bandwidth directly benefit texture-heavy scenes and higher resolutions.

Where does the GTX 650 Ti Boost win? It wins in average benchmark score among its own peer group, as noted, and it wins on power efficiency per TDP relative to its performance class. Its 134 W TDP is lower than the GTX 970's 148 W, and it requires only a single 6-pin power connector versus dual 6-pin on the GTX 970. Its shorter length (241 mm versus 267 mm) makes it easier to fit in smaller cases. But these are practical advantages, not performance wins. In terms of raw benchmark scores across the three shared tests, the GTX 650 Ti Boost does not register a single victory.

Architecture Differences

The two cards represent distinct architectural generations from NVIDIA. The GTX 650 Ti Boost is built on the Kepler architecture using the GK106 chip, fabricated on a 28 nm process at TSMC. It packs 2,540 million transistors into a 221 mm² die, yielding a transistor density of 11.5 million per mm². The GTX 970, in contrast, uses the Maxwell 2.0 architecture with the GM204 chip, also on a 28 nm process but with 5,200 million transistors spread across a 398 mm² die, achieving a higher density of 13.1 million per mm². The GTX 970's transistor count is more than double that of the GTX 650 Ti Boost, which directly explains its superior compute capability.

The shading unit count tells a similar story: 768 shading units on the GTX 650 Ti Boost versus 1,664 on the GTX 970, a 2.17x increase. Texture mapping units jump from 64 to 104, and ROPs more than double from 24 to 56. These translate into pixel rates of 16.51 GPixel/s for the GTX 650 Ti Boost and 65.97 GPixel/s for the GTX 970, a 4x difference. Texture rates are 66.05 GTexel/s versus 122.5 GTexel/s, a 1.85x gap. FP32 throughput is 1.585 TFLOPS for the older card and 3.920 TFLOPS for the newer one, a 2.47x advantage.

Memory architecture also diverges sharply. The GTX 650 Ti Boost uses 2 GB of GDDR5 on a 192-bit interface, while the GTX 970 uses 4 GB on a 256-bit bus. Memory clocks are 1502 MHz (6 Gbps effective) versus 1753 MHz (7 Gbps effective), yielding bandwidths of 144.2 GB/s and 224.4 GB/s respectively. The GTX 970 also features a newer display output suite: 1x DVI, 1x HDMI 2.0, and 3x DisplayPort 1.2, versus 2x DVI, 1x HDMI 1.4a, and 1x DisplayPort 1.2 on the GTX 650 Ti Boost. HDMI 2.0 support on the GTX 970 enables higher refresh rates and 4K output over a single cable, a capability the older card lacks.

Both cards share a 28 nm process, PCIe 3.0 x16 interface, dual-slot cooling, and a 300 W suggested PSU. The GTX 970 has a higher base clock (1050 MHz versus 980 MHz) and boost clock (1178 MHz versus 1032 MHz). The GTX 650 Ti Boost launched earlier in 2013, while the GTX 970 followed in 2014, and both are now end-of-life products.

FAQ

Head-to-Head Benchmarks

The database records three shared benchmarks between these two cards, and the GTX 970 wins all three by substantial margins. The largest gap appears in Geekbench OpenCL, where the GTX 970 scores 29,982 versus 9,302 for the GTX 650 Ti Boost, a delta of 69%. This test measures general-purpose compute performance, and the result reflects the GTX 970's 1,664 shading units and 3.920 TFLOPS FP32 throughput against the GTX 650 Ti Boost's 768 shading units and 1.585 TFLOPS. For compute workloads such as video encoding, physics simulation, or machine learning inference, the GTX 970 is more than twice as fast.

In Geekbench Metal, the GTX 970 scores 13,595 against 4,858, a delta of 64.3%. Metal is Apple's low-level graphics API, and the score difference here indicates that the GTX 970 handles geometry, tessellation, and fragment workloads far more efficiently. The GTX 970's pixel rate of 65.97 GPixel/s versus 16.51 GPixel/s for the GTX 650 Ti Boost is a primary driver of this gap, as is its 122.5 GTexel/s texture rate versus 66.05 GTexel/s.

The narrowest gap is in Geekbench Vulkan, where the GTX 970 leads 20,005 to 10,041, a delta of 49.8%. Vulkan is a cross-platform low-overhead API, and the GTX 970's newer Maxwell 2.0 architecture with Vulkan 1.4 support gives it an edge in draw call throughput and command buffer processing. Even with a smaller relative margin, the GTX 970 still delivers exactly double the score, which is a decisive victory.

Beyond these three tests, the GTX 970 has additional benchmark data that the GTX 650 Ti Boost lacks. In PassMark DirectX 9, it scores 143; in DirectX 10, 46; in DirectX 11, 71; and in DirectX 12, 41. Its PassMark G2D score is 764, G3D is 9,638, and GPU Compute is 4,073. The 3DMark Steel Nomad DX12 test yields 369. These scores cannot be directly compared to the GTX 650 Ti Boost, as that card was not subjected to the same tests, but they further illustrate the GTX 970's broad applicability across both legacy and modern APIs.

The pattern is unambiguous: the GTX 970 outperforms the GTX 650 Ti Boost by roughly 50% to 70% in every shared workload. The GTX 650 Ti Boost's only statistical consolation is its higher average benchmark score (8,067 versus 7,157), which stems from a narrower test set that omits the GTX 970's more demanding DirectX and 3DMark runs. When the two cards face identical tests, the GTX 970 wins every time, and often by a landslide.
