NVIDIA GeForce RTX 4090 D vs NVIDIA GeForce RTX 5070 Ti Mobile Comparison

Head-to-Head Benchmarks

The benchmark data shows a dominant performance advantage for the NVIDIA GeForce RTX 4090 D across every recorded test. In the two shared benchmarks, the desktop card wins both outright, with the largest margin appearing in Geekbench OpenCL. The RTX 4090 D scores 278,621 points against 143,870 for the RTX 5070 Ti Mobile, a delta of 93.7 percent. That is nearly double the mobile part's compute throughput in this API.

The Vulkan results tell a similar story, though the gap narrows slightly. The RTX 4090 D posts 246,941 points, while the RTX 5070 Ti Mobile reaches 139,213. That represents a 77.4 percent advantage for the desktop card. Both scores place the RTX 4090 D far ahead in graphics API performance, and the consistency across OpenCL and Vulkan suggests the lead is not an artifact of a single workload type.

The RTX 5070 Ti Mobile does have additional benchmarks recorded in its own entry, but the head-to-head table only includes the two Geekbench tests. In those, the mobile GPU wins zero tests, and the RTX 4090 D wins two. The average benchmark score for the RTX 4090 D is 178,050, versus 35,435 for the mobile chip. That is a fivefold difference in aggregate performance, which places the desktop card in the 98th percentile of all GPUs in the database, while the mobile part sits at the 80th percentile.

The nearest rivals for each card put these numbers in context. The RTX 4090 D trails the NVIDIA RTX PRO 5000 Blackwell by only 2.2 percent in average score, and it sits 3.1 percent behind the A100 SXM4 80 GB. The RTX 5070 Ti Mobile, meanwhile, is essentially tied with the Quadro GV100 (0.2 percent behind) and the AMD Radeon Pro Duo (1.2 percent behind), while leading the NVIDIA A2 by 2.1 percent. The mobile card's performance class is therefore much closer to workstation GPUs from previous generations than to the current desktop flagship.

Architecture Differences

The two GPUs come from different architectures and target entirely different physical environments. The RTX 4090 D uses the AD102 chip built on the Ada Lovelace architecture, fabricated by TSMC on a 5 nm process. It packs 76,300 million transistors on a die size of 609 mm². The RTX 5070 Ti Mobile uses the GB205 chip with Blackwell 2.0 architecture, also on TSMC's 5 nm node, but with 31,100 million transistors on a 263 mm² die. The transistor density is slightly higher on the desktop chip at 125.3M per mm², versus 118.3M per mm² for the mobile part.

The compute resources diverge sharply. The RTX 4090 D has 14,592 shading units, 456 texture mapping units, and 176 raster output units. The RTX 5070 Ti Mobile has 5,888 shading units, 184 TMUs, and 80 ROPs. The desktop card also carries 114 RT cores and 456 tensor cores, while the mobile chip has 46 RT cores and 184 tensor cores. These numbers translate into a massive throughput gap: the RTX 4090 D delivers 73.54 TFLOPS of FP32 and FP16 compute, while the mobile card manages 17.04 TFLOPS in both precisions. Texture rate is 1,149.1 GTexel/s versus 266.2 GTexel/s, and pixel rate is 443.5 GPixel/s versus 115.8 GPixel/s.

Memory architecture also differs fundamentally. The RTX 4090 D uses 24 GB of GDDR6X on a 384-bit bus, with 1.01 TB/s of bandwidth. The RTX 5070 Ti Mobile uses 12 GB of GDDR7 on a 192-bit bus, delivering 672.0 GB/s. The memory clock speeds reflect the different standards: 1313 MHz with 21 Gbps effective for the desktop, and 1750 MHz with 28 Gbps effective for the mobile. The mobile card's GDDR7 runs faster per pin, but the narrower bus and smaller capacity limit total bandwidth.

Power and physical design are the most striking differences. The RTX 4090 D has a TDP of 425 W, uses a triple-slot cooler, requires a 16-pin power connector, and needs an 800 W power supply. The RTX 5070 Ti Mobile has a TDP of 60 W, uses an integrated graphics package (IGP) with no power connectors, and requires no separate PSU. The desktop card measures 304 mm in length, 137 mm in height, and 61 mm in width. The mobile chip has no recorded dimensions, as it is designed for portable device integration. Bus interface also differs: PCIe 4.0 x16 for the desktop, PCIe 5.0 x16 for the mobile.

The Verdict

The data makes the choice clear: the RTX 4090 D is the superior performer in every measured benchmark. It wins both head-to-head tests by large margins, holds a fivefold lead in average benchmark score, and sits in the 98th percentile of all GPUs. The RTX 5070 Ti Mobile, by contrast, reaches only the 80th percentile and scores below several older workstation parts.

The RTX 4090 D is appropriate for scenarios where maximum compute throughput and memory bandwidth are required, and where the 425 W TDP and triple-slot footprint are acceptable. The RTX 5070 Ti Mobile is appropriate for portable systems with strict power limits, but the benchmark data shows it cannot compete with the desktop card in raw performance. The 93.7 percent OpenCL delta and 77.4 percent Vulkan delta are decisive.

The RTX 4090 D also holds advantages in memory capacity (24 GB versus 12 GB), bandwidth (1.01 TB/s versus 672.0 GB/s), and compute resources across every category. The mobile card's advantages are limited to power efficiency and the newer GDDR7 memory type, but those do not translate into benchmark wins. The production status is also relevant: the RTX 4090 D is end-of-life, while the RTX 5070 Ti Mobile is active, but the recorded data shows no performance benefit from the newer status.

Where Each One Wins

The RTX 4090 D wins in every benchmark category recorded in the database. Its advantages span compute performance, memory bandwidth, texture throughput, and pixel output. The 73.54 TFLOPS of FP32 compute versus 17.04 TFLOPS for the mobile chip makes it suitable for heavy compute workloads, and the 1.01 TB/s bandwidth supports large data sets. The 24 GB memory capacity also doubles the mobile part's 12 GB, which matters for tasks that exceed the smaller frame buffer.

The RTX 5070 Ti Mobile wins only in power efficiency and portability. Its 60 W TDP versus 425 W means it can operate in systems without discrete cooling or high-wattage power supplies. The GDDR7 memory runs at a higher effective speed (28 Gbps versus 21 Gbps), but the narrower bus and smaller capacity reduce the practical benefit. The mobile card also uses PCIe 5.0 x16, which is a newer interface standard than the desktop card's PCIe 4.0 x16, though no benchmark data shows a performance impact from this difference.

For users who prioritize raw performance and have the physical space and power budget, the RTX 4090 D is the clear choice. For users who need GPU acceleration in a portable device with a 60 W power limit, the RTX 5070 Ti Mobile is the only option that fits, but the data shows it delivers roughly a fifth of the aggregate performance (35,435 average versus 178,050). The RTX 4090 D also holds a 98th percentile rank against all GPUs, while the mobile part sits at 80th, meaning the desktop card outperforms nearly all recorded GPUs, whereas the mobile chip trails a significant portion of the database.
