NVIDIA GeForce RTX 4070 Mobile vs NVIDIA T600 Mobile Comparison

The Verdict

The data in the database draws a clear line between these two mobile GPUs. The NVIDIA GeForce RTX 4070 Mobile is the decisive choice for any workload that leans on raw compute, rasterization, or modern graphics features. It wins both recorded head-to-head benchmarks by a wide margin, and its architecture carries capabilities the T600 Mobile simply does not have. The NVIDIA T600 Mobile, meanwhile, is an older, end-of-life part built for a different era of mobile workstations. It is not competitive on performance, but it does occupy a lower power envelope, which may matter in specific ultra-thin portable designs.

For a user prioritizing maximum frames per second, compute throughput, or future-facing API support, the RTX 4070 Mobile is the only rational pick from this pair. The benchmark results show a 67.5 percent advantage in Geekbench OpenCL and a 72.1 percent advantage in Geekbench Vulkan. Those are not marginal gaps; they represent a generational leap in capability. The T600 Mobile should only be considered when power draw is the absolute constraint, and even then, the data does not show any performance metric where it leads.

FAQ

A: The NVIDIA GeForce RTX 4070 Mobile wins both head-to-head tests. It scores 109197 in Geekbench OpenCL versus 35486 for the T600 Mobile, a delta of 67.5 percent. In Geekbench Vulkan, it scores 108367 versus 30211, a delta of 72.1 percent.

Q: How do the two GPUs compare in terms of average benchmark score?

A: The T600 Mobile has an average benchmark score of 32849, while the RTX 4070 Mobile has an average of 27435. Despite this, the RTX 4070 Mobile wins every direct head-to-head test in the database. The T600 Mobile sits at the 77th percentile against all GPUs, while the RTX 4070 Mobile sits at the 73rd percentile.

Q: Do both GPUs support ray tracing?

A: No. The RTX 4070 Mobile includes 36 RT cores and 144 tensor cores, while the T600 Mobile lists no RT cores and no tensor cores in the database. This means hardware-accelerated ray tracing and tensor-based features are only available on the RTX 4070 Mobile.

Q: What are the memory specifications of each GPU?

A: The T600 Mobile has 4 GB of GDDR6 on a 128-bit bus with 192.0 GB/s bandwidth. The RTX 4070 Mobile has 8 GB of GDDR6 on a 128-bit bus with 256.0 GB/s bandwidth. The RTX 4070 Mobile doubles capacity and provides 33 percent more bandwidth.

Q: Which GPU has a smaller manufacturing process?

A: The RTX 4070 Mobile is built on a 5 nm process, while the T600 Mobile uses 12 nm. Both are fabricated by TSMC, but the RTX 4070 Mobile packs 22,900 million transistors into a 188 mm² die, versus 4,700 million transistors in a 200 mm² die for the T600 Mobile.

Q: What is the power draw difference between the two?

A: The T600 Mobile has a TDP of 40 W, while the RTX 4070 Mobile has a TDP of 115 W. The RTX 4070 Mobile consumes nearly three times the power budget, which correlates with its far higher performance figures.

Architecture Differences

The two GPUs represent entirely different generations of NVIDIA design. The T600 Mobile is built on the Turing architecture, using the TU117 chip, and belongs to the Quadro Turing-M (Tx000) generation. The RTX 4070 Mobile uses the Ada Lovelace architecture with the AD106 chip, part of the GeForce 40 Mobile generation. That architectural gap explains most of the performance delta observed in the benchmarks.

The manufacturing process is a major dividing line. The T600 Mobile is fabricated on TSMC's 12 nm node, while the RTX 4070 Mobile uses TSMC's 5 nm node. This is not a cosmetic difference. The transistor density tells the story: the T600 Mobile has 23.5 million transistors per square millimeter, while the RTX 4070 Mobile reaches 121.8 million per square millimeter. The RTX 4070 Mobile crams 22,900 million transistors into a 188 mm² die, which is smaller than the T600 Mobile's 200 mm² die despite holding nearly five times the transistor count.

Feature support diverges sharply as well. The RTX 4070 Mobile includes 36 RT cores and 144 tensor cores, enabling hardware ray tracing and AI-accelerated workloads. The T600 Mobile lists no such hardware in the database. The API support reflects this: the RTX 4070 Mobile supports DirectX 12 Ultimate (12_2), while the T600 Mobile tops out at DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4, so those are not differentiators, but the DirectX gap matters for modern game titles and graphics effects.

The memory subsystem also differs in capacity and speed. The T600 Mobile has 4 GB of GDDR6 at 12 Gbps effective, while the RTX 4070 Mobile has 8 GB of GDDR6 at 16 Gbps effective. Both use a 128-bit bus, but the higher-speed memory on the RTX 4070 Mobile yields 256.0 GB/s versus 192.0 GB/s. The RTX 4070 Mobile also supports PCIe 4.0 x8, while the T600 Mobile uses PCIe 3.0 x16, which affects how quickly data can move between the GPU and the rest of the system.

Specification Differences

The core configuration differs by a wide margin. The T600 Mobile has 896 shading units, 56 texture mapping units, and 32 ROPs. The RTX 4070 Mobile has 4608 shading units, 144 TMUs, and 48 ROPs. That is roughly five times the shader count and 2.5 times the TMU count. The pixel rate scales accordingly: 45.12 GPixel/s for the T600 Mobile versus 81.36 GPixel/s for the RTX 4070 Mobile. Texture rate is 78.96 GTexel/s versus 244.1 GTexel/s.

Clock speeds are also higher on the newer part. The T600 Mobile runs at a base clock of 780 MHz and a boost clock of 1410 MHz. The RTX 4070 Mobile runs at 1395 MHz base and 1695 MHz boost. The memory clock is 1500 MHz (12 Gbps effective) versus 2000 MHz (16 Gbps effective). The floating-point throughput reflects the combined effect of more cores and higher clocks: the T600 Mobile delivers 2.527 TFLOPS FP32 and 5.053 TFLOPS FP16 (2:1), while the RTX 4070 Mobile delivers 15.62 TFLOPS FP32 and 15.62 TFLOPS FP16 (1:1). The RTX 4070 Mobile does not halve its FP16 rate, which is a notable architectural improvement.

Power and interface differences are significant. The T600 Mobile has a TDP of 40 W, while the RTX 4070 Mobile has a TDP of 115 W. Both are listed as IGP slot width with no power connectors, and both have display outputs marked as portable device dependent. The bus interface differs: PCIe 3.0 x16 for the T600 Mobile versus PCIe 4.0 x8 for the RTX 4070 Mobile. The T600 Mobile is marked end-of-life, released in April 2021, while the RTX 4070 Mobile is active, released in January 2023.

Head-to-Head Benchmarks

The database records two direct benchmark comparisons between these GPUs, and the RTX 4070 Mobile wins both. In Geekbench OpenCL, the T600 Mobile scores 35486 while the RTX 4070 Mobile scores 109197. The delta is 67.5 percent in favor of the RTX 4070 Mobile. That is a massive gap, more than tripling the older GPU's score. OpenCL performance is a good proxy for general compute workloads, and the data suggests the RTX 4070 Mobile is in a different performance class entirely.

In Geekbench Vulkan, the result is even more lopsided. The T600 Mobile scores 30211, while the RTX 4070 Mobile scores 108367. The delta is 72.1 percent. Vulkan is a low-level graphics API that stresses the raw throughput of the GPU, and the RTX 4070 Mobile's advantage here points to its much larger shader array, higher clocks, and more efficient architecture. The T600 Mobile's Vulkan score is also lower than its OpenCL score, while the RTX 4070 Mobile's Vulkan score is only slightly lower than its OpenCL result, indicating better cross-API consistency on the newer part.

Looking at the broader benchmark context, the T600 Mobile's average score of 32849 places it near the NVIDIA P104-100, which averages 32982, a delta of 0.4 percent against the T600. It also sits close to the AMD Radeon RX 590 GME (32601, 0.8 percent) and the AMD FirePro S9300 X2 (32540, 0.9 percent). The T550 Mobile is slightly ahead at 33161, a 0.9 percent delta. The RTX 4070 Mobile, by contrast, averages 27435, which puts it near the AMD Radeon RX 6700 XT (27425, 0 percent), the NVIDIA GeForce RTX 3090 (27565, 0.5 percent ahead of the 4070 Mobile), and the RTX PRO 4000 Blackwell (27135, 1.1 percent behind). These rival comparisons show that the RTX 4070 Mobile, despite being a mobile part, trades blows with desktop-class GPUs, while the T600 Mobile competes in a much lower performance tier.

The wins tally is unambiguous: the RTX 4070 Mobile records 2 wins, the T600 Mobile records 0. The percentile rankings are the only metric where the T600 Mobile leads, sitting at 77 versus 73 for the RTX 4070 Mobile, but that ranking reflects the distribution of all GPUs in the database, not the direct comparison between these two parts. Every head-to-head measurement in the database favors the RTX 4070 Mobile, and the architectural differences in the specification data fully corroborate that result.
