After the release of the Hopper architecture GPU, NVIDIA’s new Ada Lovelace architecture GPU was also put on the agenda.
In the latest tweet, @Kopite7kimi disclosed the details of the GeForce RTX 4090/4070 graphics card based on Ada Lovalace.The NVIDIA Geforce RTX 4090 Ti/4080 will be built on the optimized AD102 core, while the RTX 4070 will use the optimized AD104 core.
According to rumors, the GeForce RTX 4090 uses the same AD102 GPU as the RTX 4090 Ti, but Lao Huang needs to use a superb knife for positioning.The NVIDIA AD102 core has 144 sets of stream processor units built in, with a total of 18,432 CUDA cores.
NVIDIA has greatly increased the L2 cache. The flagship AD102 will have a 96MB L2 cache, which is 16 times that of the previous generation GA102 (6MB L2).The graphics card is equipped with 384-bit wide GDDR6x memory, which can bring a speed close to 1TB/s at a frequency of 21Gbps.
Under the circumstance that the specifications and performance are greatly improved, the power consumption of the AD102 core is also greatly increased. Among them, the power consumption of the RTX 4090 with 24GB GDDR6X memory reaches 600W. In order to better suppress the temperature, AIC manufacturers may introduce a hybrid cooling (air cooling + water cooling) design, and the traditional three-slot multi-fan radiator has been difficult to meet the demand.
RTX 4070 with AD104 core (it is said that the PCB board is PG141-SKU341), the graphics card has 60 sets of stream processor units, a total of 7680 CUDA cores and 48MB L2 cache, with 12GB capacity, 192-bit wide GDDR6 memory, 16 ～18Gbps brings bandwidth of 384GB/s～432GB/s, and the power consumption reaches 300W.
Editor’s comment:
Since the RTX 30 series using the Ampere architecture, it is no longer a secret that the power consumption of the graphics card “explodes”, and the power consumption of the flagship Ada Lovelace exceeds 600W is also expected.
In the face of landslide-like “mine” difficulties, the pricing of 40 series graphics cards will be more concerned by players. After all, many graphics cards on the market have been “mine” at this stage, which also leads to users’ trust in AIC, NVIDIA and AMD products. crisis.
