NVIDIA TITAN RTX REVIEW!!!

The Titan RTX launch was decidedly unceremonious. Members of the tech press knew that the card was coming but didn’t receive one to test. Nvidia undoubtedly knew its message would be obscured by comparisons drawn between Titan RTX and the other TU102-based card, GeForce RTX 2080 Ti, in games. Based on a complete TU102 processor, As it appears in the 2080 Ti, though, TU102 features 68 active Streaming Multiprocessors. Four of the chip’s 72 are turned off. One of its 32-bit memory controllers is also disabled, taking eight ROPs and 512KB of L2 cache with it. Titan RTX is based on the same processor, but with every block active. That means the card boasts a GPU with 72 SMs, 4,608 CUDA cores, 576 Tensor cores, 72 RT cores, 288 texture units, and 36 PolyMorph engines. Not only does Titan RTX sport more CUDA cores than GeForce RTX 2080 Ti, it also offers a higher GPU Boost clock rating (1,770 MHz vs. 1,635 MHz). As such, its peak single-precision rate increases to 16.3 TFLOPS. Each SM does contain a pair of FP64-capable CUDA cores as well, yielding a double-precision rate that’s 1/32 of TU102’s FP32 performance, or 0.51 TFLOPS. This is one area where Titan RTX loses big to its predecessor. Titan V’s GV100 processor is better in the HPC space thanks to 6.9 TFLOPS peak FP64 performance (half of its single-precision rate). A quick run through SiSoftware’s Sandra GPGPU Arithmetic benchmark confirms Titan V’s strength, along with the mixed-precision support inherent to Turing and Volta, which Pascal lacks. The GPU’s GPCs are fed by 12 32-bit GDDR6 memory controllers, each attached to an eight-ROP cluster and 512KB of L2 cache yielding an aggregate 384-bit memory bus, 96 ROPs, and a 6MB L2 cache. At the same 14 Gb/s data rate, one extra memory emplacement buys Titan RTX about 9% more memory bandwidth than GeForce RTX 2080 Ti.Whereas GeForce RTX 2080 Ti Founders Edition utilizes Micron’s MT61K256M32JE-14:A modules, the company doesn’t have any 16Gb ICs in its parts catalog. Samsung, on the other hand, does offer a higher-density K4ZAF325BM-HC14 module with a 14 Gb/s data rate. Twelve of them give Titan RTX its 24GB capacity and 672 GB/s peak throughput. Lots of extra memory, a GPU with more active resources, and faster clock rates necessitate a higher thermal design power rating. Whereas GeForce RTX 2080 Ti Founders Edition is specified at 260W, Titan RTX is a 280W card. That 20W increase is no problem at all for the pair of eight-pin auxiliary power connectors found along the top edge, nor is a challenge for Nvidia’s power supply and thermal solution, both of which appear identical to its GeForce RTX 2080 Ti. The uP9512 supports Nvidia’s Open Voltage Regulator Type 4i+ technology with PWMVID. This input is buffered and filtered to produce a very accurate reference voltage. The output voltage is then precisely controlled to the reference input. An integrated SMBus interface offers enough flexibility to optimize performance and efficiency, while also facilitating communication with the appropriate software. All 13 voltage regulation circuits are equipped with an ON Semiconductor FDMF3170 Smart Power Stage module with integrated PowerTrench MOSFETs and driver ICs.
