COMPARE ATI MOBILITY RADEON HD 4670 TO GEFORCE 680M PROFESSIONAL
used by AMD and also for the professional GA100 Ampere chip).ĭisplayPort 1.4, HDMI 2.1, PCIe 4.0 x16, 17.8 SP-FP TFLOPS Peak, 143 Tensor Performance Peak, up to 384 GB/s Memory Bandwidth, Resizable BAR, Support for Modern Standby 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. 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 A4000 only uses 5,120 of the 6,144 CUDA cores. The raytracing and tensor cores on the chip were also improved according to Nvidia. With Turing all shaders could still execute FP32 or INT32 instructions. The GA104 chip offers 6,144 FP32 ALUs of which half can also execute INT32 instructions (i.e. The desktop variant of the A4000 however, is a lot faster. At a similar power consumption level the RTX A4000 should be clearly faster than the old Quadro RTX 4000 and 4000 Max-Q.
Both GPUs depend heavily on good cooling and a high TGP for good performance. The raw performance should be similar to the GeForce RTX 3070 for laptops at the same TGP level. 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 GPU supports eDP 1.4b to connect the internal monitor and DisplayPort 1.4 and HDMI 2.1 for external connections. It supports PCIe 4.0 and will be available in different variants from 80 - 140 Watt (TGP) with different clock speeds (and performance). 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 is based on the GA104 Ampere chip and similar to the consumer GeForce RTX 3080 Laptop GPU. The NVIDIA RTX A4000 Laptop GPU or A4000 Mobile is a professional graphics card for mobile workstations.
