Finally, the mid-range AMD seems able to hold its own against NVIDIA’s graphics cards. Seems, because we will have to check / test all that.
Eagerly awaited by many players who would like to see AMD stand up to the current hegemony of NVIDIA, the Radeon RX 7800XT card should arrive in September, Lisa Su herself confirmed it.
All specs revealed!
What the president of AMD had not planned on the other hand, is the anticipated online publication of the product sheet at PowerColor. No doubt this is a handling error, but the damage is done.

Indeed, on the official PowerColor website, all the specifications of the RX 7800XT have been put online without it being possible to speak of an unfounded rumor or a dirty rumor. The model thus presented is not the MBA reference card (made by AMD or conceived by AMD in good French), but the Radeon RX 7800XT Red Devil Hero that the manufacturer is preparing.
In fact, it is possible that some of the advanced values are not quite identical to those that AMD would announce at the time of its presentation. We are thinking in particular of the operating frequencies of the GPU, the partners tending to boost everything a little.
Fewer stream processors than 6800XT
Still, if the specifications thus published are correct, the GPU used on these Radeon RX 7800XT would have fewer stream processors than the chip used on the older generation, the RX 6800XT. We are talking about 3,840 SP (stream processors or stream processors) against 4,608 on the “ancestor”.
In terms of operating frequencies, it was therefore mentioned by PowerColor 2,255 MHz in gaming and 2,565 MHz in boost, while the reference frequencies for the AMD model would be, respectively, 2,210 and 2,520 MHz, again according to PowerColor. As advanced by several rumors, the video memory is indeed 16 GB of GDDR6 at 18 Gbps with a 256-bit interface bus and therefore a bandwidth of 576 GB/s.

The video memory would thus have the same characteristics as that used on the recent RX 7900GRE and we remain close to what the RX 6800XT offered. Without mentioning too much the “energy” part, PowerColor indicated that an 800 watt power supply is recommended and that the card incorporates two 8-pin sockets whereas, as the photos show, the cooling is entrusted to a classic triple-fan system.
Fans which are used to dissipate the heat evacuated by the imposing heatsink and the 8 heat pipes, a copper plate providing contact with the GPU. Nothing more important to report for the moment, PowerColor not having revealed the selling price of its card.
