Bloggers and media showed unboxing Radeon RX 7900 XTX and RX 7900 XT - reviews will appear on December 12

AMD allowed core media and tech bloggers to publish materials with unboxing of the latest graphics cards Radeon RX 7900 XTX and RX 7900 XT, reports VideoCardz.
However, reviewers can not publish information about their performance or reviews - it will have to wait until next week.Image source: VideoCardzThe majority of reviewers got their hands on a reference version of the Radeon RX 7900 XT and Radeon RX 7900 XTX.
While at first glance the two cards don't seem to differ from each other, a closer look reveals that this is not the case.
The flagship Radeon RX 7900 XTX is slightly taller and longer than the Radeon RX 7900 XT.
In addition, the video cards have a different RGB backlight configuration.
However, both benchmark gas pedals have the same thickness of two expansion slots.
In addition, both video cards received two 8-pin connectors for additional power.

The flagship model has a wider one.
The older version uses a board marked D704, the younger one uses a board marked D702.
It is obvious that apart from the size of the circuit boards the graphics cards also differ in their VRM power subsystems.
However, more detailed information on this will be known after the novelties will be available for disassembly.

British publication Overclock3D has shared a picture of XFX Radeon RX 7900 XTX MERC 310, images of which flashed quite recently.
Source image: Overclock3DThe German edition HardwareLUXX, full independent reviews of the Radeon RX 7900 XT and Radeon RX 7900 XTX will begin to appear on December 12, the day before the actual start of new products.Recall that in the benchmark flagship Radeon RX 7900 XTX estimated at $ 999, the junior Radeon RX 7900 XT has a price tag of $ 899.
The first uses a full-fledged GPU Navi 31 with 6144 stream processors and is equipped with 24 GB of GDDR6 memory.
The second one is based on a \"cut down\" Navi 31 GPU with 5376 stream processors and 20 GB of GDDR6 memory.

NVIDIA engineer showed prototypes of GeForce RTX 4090 cooling systems and fans

Manufacturers usually don't show early prototypes of their products.
However, there are exceptions.
On the popular YouTube channel Gamers Nexus, NVIDIA engineer Malcolm Gutenberg (Malcom Gutenburg), which deals with graphics card cooling, shared some interesting details about the development of the new flagship GeForce RTX 4090.Image source: Gamers NexusIn particular, Gutenberg talked about the cooling system features GeForce RTX 4090 graphics gas pedal, and also showed early prototypes of cooling systems that NVIDIA has designed for this graphics card.
An NVIDIA engineer showed a cut radiator of the GeForce RTX 4090 Founders Edition reference version.
In comparison with the previous generation flagship, GeForce RTX 3090, the new graphics card has changed the design of the evaporation chamber.
It became wider, due to which the contact area with the graphics processor increased.The radiator of the cooling system of the new flagship also underwent changes.
For example, the company's engineers increased the height of its ribs to increase the area of heat dissipation.Also NVIDIA engineer showed early prototypes of the parts of the radiator, which are installed fans.
These prototypes were used to design the cooling system based on airflow and noise level data.
NVIDIA had previously said that it had developed multiple fan models for use in the GeForce RTX 4090, but ultimately chose the most optimal one.
The fan has increased in size relative to the GeForce RTX 3090.
The manufacturer did this not only to increase airflow, but also to improve the acoustic characteristics of the cooling system to reduce its noise level.
Gamers Nexus video also showed the GeForce RTX 4090 graphics card board with the Ada Lovelace AD102 GPU and other elements.
Recall that sales of the GeForce RTX 4090 graphics card will begin on October 12.
