When Nvidia launched its Ada Lovelace household of graphics processing models earlier this week, it primarily targeted on its top-of-the-range AD102 GPU and its flagship GeForce RTX 4090 graphics card. It did not launch too many particulars about its AD103 and AD104 graphics chips. Thankfully, Nvidia uploaded its Ada Lovelace whitepaper immediately that comprises a great deal of information concerning the new GPUs and fills in lots of gaps. We have up to date the RTX 40-series GPUs every part we all know hub with the brand new particulars, however this is the overview of the brand new and attention-grabbing data.
Large GPUs for Large Gaming
We already know that Nvidia’s range-topping AD102 is a 608-mm^2 GPU containing 76.3 billion transistors, 18,432 CUDA cores, and 96MB of L2 cache. We now additionally know that AD103 is a 378.6 mm^2 graphics processor that includes 45.9 billion transistors, 10,240 CUDA cores, and 64MB L2 cache. As for the AD104, it has a die measurement of 294.5 mm^2, 35.8 billion transistors, 7680 CUDA cores, and 48MB of L2.

One of many attention-grabbing issues that Nvidia tells in its whitepaper is that Ada Lovelace GPUs use high-speed transistors in essential paths to spice up most clock speeds. In consequence, its fully-enabled AD102 GPU with 18,432 CUDA cores is ”able to working at clocks over 2.5 GHz, whereas sustaining the identical 450W TGP.” Maintaining this in thoughts, we’re not stunned that the corporate is speaking about 3.0 GHz clocks for the GeForce RTX 4090 (with 16,384 CUDA cores) reached in its labs. At 3.0 GHz, the GeForce RTX 4090 will completely headline our listing of the finest graphics playing cards round.

Along with excessive clocks, Nvidia’s Ada Lovelace GPU additionally boast huge L2 caches that enhance efficiency in compute intensive workloads (e.g., ray tracing, path tracing, simulations, and so on.) and reduces reminiscence bandwidth necessities. Primarily, Nvidia’s Ada GPUs take a web page from RDNA 2 Infinity Cache’s e book right here, though we imagine that basic targets for the brand new structure had been set nicely earlier than AMD’s Radeon RX 6000-series merchandise debuted in 2020.
