NVIDIA RTX A4000 Laptop GPU vs NVIDIA GeForce RTX 4060 Ti 16G vs NVIDIA GeForce RTX 4060 Ti 8G

The NVIDIA RTX A4000 Laptop GPU or A4000 Mobile is a professional graphics card for mobile workstations. It is based on the GA104 Ampere chip and similar to the consumer GeForce RTX 3080 Laptop GPU. It offers the same 5.120 graphics cores, 40 RT cores, 160 Tensor cores and 8 GB GDDR6 graphics memory with a 256 Bit memory bus. It supports PCIe 4.0 and will be available in different variants from 80 - 140 Watt (TGP) with different clock speeds (and performance). The GPU supports eDP 1.4b to connect the internal monitor and DisplayPort 1.4 and HDMI 2.1 for external connections.

There is no more Max-Q variant (formerly used for the low power variants) but every OEM can choose to implement Max-Q technologies (Dynamic Boost, WhisperMode).

The raw performance should be similar to the GeForce RTX 3070 for laptops at the same TGP level. Both GPUs depend heavily on good cooling and a high TGP for good performance. At a similar power consumption level the RTX A4000 should be clearly faster than the old Quadro RTX 4000 and 4000 Max-Q. The desktop variant of the A4000 however, is a lot faster.

The GA104 chip offers 6,144 FP32 ALUs of which half can also execute INT32 instructions (i.e. 3,072 INT32 ALUs). With Turing all shaders could still execute FP32 or INT32 instructions. The raytracing and tensor cores on the chip were also improved according to Nvidia. The A4000 only uses 5,120 of the 6,144 CUDA cores. The Ampere chips also include an improved 5th generation video encoder (NVENC for H.264 and H.265) and a 7th generation decoder (for various formats now including AV1).

The GA104 chip is manufactured by Samsung in 8nm (8N), which is not quite able to keep up with the 7nm node at TSMC (e.g. used by AMD and also for the professional GA100 Ampere chip).

The Nvidia GeForce RTX 4060 Ti is a mid-range desktop GPU which is manufactured in a 5 nm process at TSMC. The manufacturer thus rounds off its current Ada-Lovelace lineup further in the direction of the mid-range. The AD106 is used as the chip. It combines 4,352 CUDA cores with 8 GB GDDR6. An Nvidia GeForce RTX 4060 Ti with 16 GB VRAM is supposed to follow later. The memory interface is 128 bits, which results in a memory bandwidth of only 288 GB/s.

Features

The Nvidia GeForce RTX 4060 Ti is not deprived of the features that have already arrived with the high-end models of the Ada-Lovelace generation, such as DLSS 3.0 with frame generation. Thus, the new mid-range clearly stands out from the Nvidia GeForce RTX 3060 Ti and can gain a significant advantage in games that offer these features. 

Performance

Without DLSS, the performance of an Nvidia GeForce RTX 4060 Ti is about 10% better than that of an Nvidia GeForce RTX 3060 Ti. Compared to AMD, the Nvidia GeForce RTX 4060 Ti positions itself exactly between an AMD Radeon RX 6750 XT and an AMD Radeon RX 6800, although AMD has a small advantage here with the larger VRAM when it goes beyond 1080p. However, this is not the intended goal of the Nvidia GeForce RTX 4060 Ti, as this is rather a graphics card for the 1,080p gaming range.
