After the release of hopper architecture GPU, NVIDIA's new ADA Lovelace architecture GPU has also been put on the agenda. In the latest tweet, @ kopite7kimi disclosed in detail the details of geforce RTX 4090 / 4070 graphics card based on ADA lovalace NVIDIA geforce RTX 4090 Ti / 4080 will be built based on the optimized ad102 core, while RTX 4070 will use the optimized AD104 core
According to rumors, geforce RTX 4090 uses the same ad102 GPU as RTX 4090 Ti, but Lao Huang needs to use exquisite knife technique for positioning NVIDIA ad102 core has built-in 144 groups of stream processor units, with a total of 18432 CUDA cores
NVIDIA significantly increases L2 cache. The flagship ad102 will have 96MB L2 cache, 16 times that of the previous generation ga102 (6MB L2) The graphics card is equipped with 384 bit wide gddr6x video memory, which can bring a speed of nearly 1TB / s at the frequency of 21gbps.
When the specification and performance are greatly improved, the power consumption of ad102 core is also greatly increased. The power consumption of RTX 4090 equipped with 24GB gddr6x video memory reaches 600W. In order to improve the pressing temperature, AIC manufacturers may introduce a hybrid heat dissipation (air cooling + water cooling) design. 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 is pg141-sku341). The graphics card has 60 groups of stream processor units, a total of 7680 CUDA cores and 48MB L2 cache. It is matched with gddr6 video memory with 12gb capacity and 192 bit width. 16 ~ 18gbps brings 384gb / S ~ 432gb / S bandwidth and 300W power consumption.
Since the RTX 30 series adopting ampere architecture, the "explosion" of graphics card power consumption is no longer a secret. It is also expected that the power consumption of flagship ADA Lovelace exceeds 600W.
In the face of avalanche like "mining" difficulties, the pricing of 40 Series graphics cards will be more concerned by players. After all, many graphics cards on the market have been "mining" at this stage, which also leads to a crisis of trust in AIC, NVIDIA and AMD products.
