Architecture Differences

The RTX 4080 Mobile is built on the Ada Lovelace architecture using the AD104 chip, manufactured on a 5 nm process at TSMC. It integrates 35,800 million transistors across a 294 mm² die, yielding a transistor density of 121.8 million per mm². The T600 Mobile, in contrast, uses the older Turing architecture with the TU117 chip, fabricated on TSMC’s 12 nm node. It contains 4,700 million transistors on a 200 mm² die, for a density of 23.5 million per mm². This generation gap explains the substantial differences in compute capacity and power efficiency.

The RTX 4080 Mobile’s shader array is dramatically larger: 7,424 shading units, 232 texture mapping units, and 80 render output units. The T600 Mobile has 896 shading units, 56 TMUs, and 32 ROPs. The RTX 4080 Mobile also adds 58 dedicated ray tracing cores and 232 tensor cores, while the T600 Mobile has none. This makes the RTX 4080 Mobile a fully featured modern GPU for real-time ray tracing and AI-accelerated workloads, whereas the T600 Mobile is a simpler, more limited part.

Memory subsystems differ as well. The RTX 4080 Mobile uses 12 GB of GDDR6 on a 192-bit interface, with memory clocked at 2250 MHz (18 Gbps effective) for 432.0 GB/s bandwidth. The T600 Mobile has 4 GB of GDDR6 on a 128-bit bus, at 1500 MHz (12 Gbps effective), providing 192.0 GB/s. The RTX 4080 Mobile also supports PCIe 4.0 x16, while the T600 Mobile uses PCIe 3.0 x16. Both are integrated (IGP) form factors with no power connectors, but TDP ratings differ: 110 W for the RTX 4080 Mobile versus 40 W for the T600 Mobile.

Feature support reflects the generational split. The RTX 4080 Mobile supports DirectX 12 Ultimate (12_2), the T600 Mobile only DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The RTX 4080 Mobile’s FP32 throughput is 24.72 TFLOPS, and its FP16 is also 24.72 TFLOPS (1:1). The T600 Mobile delivers 2.527 TFLOPS FP32 and 5.053 TFLOPS FP16 (2:1), meaning its FP16 rate is double its FP32 rate, a different ratio than the RTX 4080 Mobile’s 1:1.

Head-to-Head Benchmarks

The database records two shared benchmarks between the RTX 4080 Mobile and the T600 Mobile: Geekbench OpenCL and Geekbench Vulkan. The RTX 4080 Mobile wins both, and the margins are decisive.

In Geekbench OpenCL, the RTX 4080 Mobile scores 159,575 against the T600 Mobile’s 35,486. That is a 349.7% advantage, meaning the RTX 4080 Mobile is roughly 4.5 times faster in this general-purpose compute test. This aligns with its far higher shader count, FP32 throughput, and memory bandwidth. The T600 Mobile’s 2.527 TFLOPS FP32 peak is a fraction of the RTX 4080 Mobile’s 24.72 TFLOPS, so the OpenCL result reflects the raw compute resource gap.

In Geekbench Vulkan, the RTX 4080 Mobile scores 145,807 versus 30,211 for the T600 Mobile, a 382.6% lead. This is the largest relative win for the RTX 4080 Mobile in the head-to-head set. Vulkan exercises graphics and compute paths, and the RTX 4080 Mobile’s superior pixel rate (133.2 GPixel/s versus 45.12 GPixel/s) and texture rate (386.3 GTexel/s versus 78.96 GTexel/s) reinforce its dominance. The T600 Mobile’s 32 ROPs and 56 TMUs are outmatched by the RTX 4080 Mobile’s 80 ROPs and 232 TMUs.

Across the two tests, the RTX 4080 Mobile wins 2 out of 2. The T600 Mobile has no winning benchmark in this comparison. The average benchmark score for the RTX 4080 Mobile is 38,135, placing it at the 81st percentile among all GPUs, while the T600 Mobile’s average is 32,849 at the 77th percentile. These averages include a broader suite for the RTX 4080 Mobile (which has additional Passmark scores) and only the two Geekbench scores for the T600 Mobile, but the percentile ranking confirms the RTX 4080 Mobile sits higher in the overall distribution.

Where Each One Wins

The RTX 4080 Mobile wins in every measured category. It is the clear choice for any workload that demands high compute throughput, large memory capacity, or modern API features. Its 12 GB frame buffer and 432.0 GB/s bandwidth make it suitable for large datasets, high-resolution textures, and memory-intensive rendering. The 58 RT cores and 232 tensor cores enable hardware-accelerated ray tracing and AI-based features such as DLSS, which the T600 Mobile cannot provide. The 1:1 FP16/FP32 ratio also means it handles mixed-precision compute without a throughput penalty, a benefit for scientific and machine learning tasks that use FP16.

The T600 Mobile, despite losing every head-to-head benchmark, has a role in specific scenarios. Its 40 W TDP is far lower than the RTX 4080 Mobile’s 110 W, so it fits into thermally constrained notebooks or compact systems where power draw is the primary limitation. Its smaller die and older node also mean lower production complexity, though it is now end-of-life. For basic 2D desktop work, light 3D rendering, or legacy DirectX 12 (12_1) workloads, the T600 Mobile provides adequate performance. Its 2.527 TFLOPS FP32 and 192.0 GB/s bandwidth are sufficient for entry-level CAD or office graphics, especially where the GPU is not the bottleneck.

For users who need raw performance, the RTX 4080 Mobile is overwhelmingly superior. The 349.7% OpenCL lead and 382.6% Vulkan lead leave no ambiguity. For users who prioritize low power consumption and minimal heat output in a thin-and-light laptop, the T600 Mobile offers a functional baseline, but it cannot match the RTX 4080 Mobile’s feature set or speed. The percentile ranks (81st versus 77th) confirm that the RTX 4080 Mobile is positioned higher in the overall GPU landscape, and its active production status means ongoing driver and software support, while the T600 Mobile’s end-of-life status suggests a shrinking ecosystem.

In short: the RTX 4080 Mobile is the performance pick for gaming, rendering, AI, and high-bandwidth compute. The T600 Mobile is a legacy, low-power option for basic tasks where 40 W is the hard limit. The database’s benchmark data shows no scenario where the T600 Mobile outperforms the RTX 4080 Mobile.
