NVIDIA GeForce GTX 980 Ti vs NVIDIA T600 Mobile Comparison

Where Each One Wins

The data splits these two NVIDIA offerings into clearly different roles. The GeForce GTX 980 Ti is the raw performance champion, winning both recorded head-to-head benchmark comparisons. In OpenCL compute workloads, it posts a score of 43513 against the T600 Mobile's 35486, a margin of 18.4%. The Vulkan gap is even wider: 47724 versus 30211, a 36.7% advantage. For any task that leans on sustained throughput, the GTX 980 Ti is the decisive pick.

The T600 Mobile, however, occupies a different niche entirely. Its 40 W thermal design power, IGP slot width, and lack of external power connectors make it a low-power embedded or mobile solution. The GTX 980 Ti draws 250 W and requires both a 6-pin and an 8-pin connector, with a suggested 600 W power supply. The T600 Mobile's average benchmark score of 32849 actually places it above the GTX 980 Ti's 28020 in the database's aggregate metric, a result that reflects how the average is computed across a different set of workloads. The T600 Mobile also holds a higher percentile rank overall at 77 versus 73.

In short, the GTX 980 Ti wins every direct performance comparison, while the T600 Mobile wins on integration efficiency and aggregate standing in the database. The former is a high-throughput desktop part; the latter is a compact, low-power unit for space-constrained systems.

Architecture Differences

The two GPUs come from different architectural generations. The T600 Mobile uses the TU117 chip built on Turing architecture, fabricated on a 12 nm process at TSMC. The GTX 980 Ti uses the GM200 chip on Maxwell 2.0 architecture, built on a 28 nm process, also at TSMC. The transistor counts reflect the generational gap: the TU117 packs 4,700 million transistors on a 200 mm² die, while the GM200 holds 8,000 million transistors on a much larger 601 mm² die. Transistor density tells the efficiency story: 23.5 million per mm² for the Turing part versus 13.3 million per mm² for the Maxwell part.

The GTX 980 Ti has far more execution hardware. It carries 2816 shading units, 176 texture mapping units, and 96 ROPs. The T600 Mobile has 896 shading units, 56 TMUs, and 32 ROPs. Neither GPU includes ray tracing cores or tensor cores. The Maxwell chip's clock speeds are higher in raw terms: 1000 MHz base and 1076 MHz boost, while the T600 Mobile runs at 780 MHz base and 1410 MHz boost. The Turing part's higher boost clock partially compensates for fewer cores, but not enough to close the throughput gap.

Memory subsystems differ substantially. The T600 Mobile uses 4 GB of GDDR6 on a 128 bit bus, delivering 192.0 GB/s of bandwidth. The GTX 980 Ti uses 6 GB of GDDR5 on a 384 bit bus, delivering 336.6 GB/s. The effective memory speed is 12 Gbps for the T600 Mobile and 7 Gbps for the GTX 980 Ti. The wider bus and larger frame buffer of the GTX 980 Ti give it a clear bandwidth advantage.

Both support DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The GTX 980 Ti adds a Metal benchmark score of 19520, while the T600 Mobile has no Metal entry. The GTX 980 Ti is a dual-slot card measuring 267 mm in length, 111 mm in height, and 40 mm in width, with display outputs including DVI, HDMI 2.0, and three DisplayPort 1.2 connections. The T600 Mobile's display outputs are listed as portable device dependent, consistent with its mobile orientation.

Head-to-Head Benchmarks

The recorded head-to-head data contains two comparisons, and the GTX 980 Ti wins both. The first is Geekbench OpenCL, where the GTX 980 Ti scores 43513 against the T600 Mobile's 35486. The delta is 18.4% in favor of the older, larger card. This is a compute-oriented test, and the GTX 980 Ti's 6.060 TFLOPS of FP32 throughput versus 2.527 TFLOPS for the T600 Mobile explains the margin. The GTX 980 Ti also has a texture rate of 189.4 GTexel/s and a pixel rate of 103.3 GPixel/s, far ahead of the T600 Mobile's 78.96 GTexel/s and 45.12 GPixel/s.

The second comparison is Geekbench Vulkan, where the GTX 980 Ti scores 47724 and the T600 Mobile scores 30211. The 36.7% gap here is larger than in OpenCL. Vulkan workloads often stress memory bandwidth and raw rasterization throughput, both areas where the GTX 980 Ti's 384 bit bus and 96 ROPs provide a substantial edge. The T600 Mobile's 128 bit bus and 32 ROPs are a structural disadvantage in this test.

Notably, the T600 Mobile does not appear in the GTX 980 Ti's nearest rivals list, and the GTX 980 Ti does not appear in the T600 Mobile's nearest rivals list. The closest competitor to the T600 Mobile in the database is the NVIDIA T550 Mobile at 33161 average score, a 0.9% difference, followed by the NVIDIA P104-100 at 32982, the AMD Radeon RX 590 GME at 32601, and the AMD FirePro S9300 X2 at 32540. The GTX 980 Ti's nearest rivals include the AMD Radeon Pro W5500X at 27973, the AMD FirePro S7150 at 28117, the AMD Radeon RX 7800M at 27883, and the AMD Radeon Pro Vega 20 at 27839, all within about a point of each other.

The average benchmark score tells a different story from the head-to-head results. The T600 Mobile averages 32849, which is 17.2% higher than the GTX 980 Ti's 28020. This discrepancy arises because the average includes a broader set of tests, and the T600 Mobile's lower power envelope may allow it to sustain performance in workloads that throttle the GTX 980 Ti. The percentile ranking confirms this: the T600 Mobile sits at the 77th percentile of all GPUs, while the GTX 980 Ti sits at the 73rd.

The specification table highlights the fundamental split: the T600 Mobile is a modern, dense, low-power chip with a smaller memory footprint, while the GTX 980 Ti is a large, power-hungry desktop card with superior raw throughput and memory bandwidth. The GTX 980 Ti's dual-slot form factor and external power requirements contrast with the T600 Mobile's IGP slot and connector-free design. The release dates are nearly six years apart, with the T600 Mobile arriving in April 2021 and the GTX 980 Ti in June 2015. Both are end-of-life products, but they target entirely different system classes.
