據報道，疑似一名 ChipHell 論壇的網友放出了 RTX 4090 的 3DMark 跑分截圖，目前該帖已被刪除。

這款顯卡在 3DMark Time Spy Extreme 中獲得了 20192 分的顯卡分，而之前的傳聞稱 RTX 4090 分數爲 19k。

該爆料人還透露了這款 GPU 頻率和溫度數據，其 GPU 達到了 3015 MHz 頻率，GPU 溫度在 55 度左右。而且只用了風冷，因爲整卡功耗爲450W，散熱設計則是按照600-800W來做的。

An alleged 3DMark Time Spy benchmark of NVIDIA's upcoming GeForce RTX 4090 graphics card has been leaked over at Chiphell forums. The NVIDIA GeForce RTX 4090 is expected to utilize 128 SMs of the 144 SMs for a total of 16,384 CUDA cores. The GPU will come packed with 96 MB of L2 cache and a total of 384 ROPs which is simply insane. The clock speeds are not confirmed yet but considering that the TSMC 4N process is being used, we are expecting clocks between the 2.0-3.0 GHz range. As for memory specs, the GeForce RTX 4090 is expected to rock 24 GB GDDR6X capacities that will be clocked at 21 Gbps speeds across a 384-bit bus interface. This will provide up to 1 TB/s of bandwidth. This is the same bandwidth as the existing RTX 3090 Ti graphics card and as far as the power consumption is concerned, the TBP is said to be rated at 450W which means that TGP may end up lower than that. The card will be powered by a single 16-pin connector which delivers up to 600W of power. It is likely that we may get 500W+ custom designs as we saw with the RTX 3090 Ti. The alleged NVIDIA GeForce RTX 4090 graphics card is said to operate at 30C at idle and 65C at load with clock speeds peaking above 3.0 GHz (3015 MHz to be precise) while the memory operates at 21 Gbps (1312.75 MHz effective). The card is said to be very large and this could be a triple fan engineering sample like the one that leaked out a few days ago.  The leaker also states that this card has a TGP of just 450W but the cooler can sustain much more than that. We can't say for sure if this was a stock or overclocked benchmark but given the previous performance rumors had said the same thing, it looks to be a stock result. In 3DMark Time Spy Extreme, the graphics card scored 20192 points which would mark a 2x uplift over the RTX 3090 and an 80% uplift over the RTX 3090 Ti. That's a crazy big performance jump and what's important is that final custom models can push this performance even higher. The NVIDIA GeForce RTX 40 series graphics cards including the RTX 4080 and RTX 4070 graphics cards will be amongst the first graphics cards besides the RTX 4090 to launch to gamers. The RTX 4090 is so far expected to launch on October 22 but an unveiling is expected at NVIDIA's GTC keynote later this month.
