The prototype of the unreleased GeForce RTX 3070 Ti graphics card with 16 GB of memory showed up in the photo

NVIDIA was planning to release another model - GeForce RTX 3070 Ti with 16 GB of memory as part of its GeForce RTX 3000 series of graphics cards.
This gas pedal for a long time appeared in various databases of regulators, but eventually did not appear on sale.
Insider MEGAsizeGPU shared photos and characteristics of unsuccessful reference graphics card.Image source: Twitter / MEGAsizeGPUIn appearance GeForce RTX 3070 Ti 16GB was an exact copy of the model with 8 GB of memory, which eventually went on sale.
However, the characteristics of cards are different.
In spite of the fact that the 16GB version was supposed to use the same GA104 GPU based on Ampere architecture with 6144 CUDA cores, 192 tensor cores and 48 RT cores as the 8GB version which went on sale, the chip of the \"older\" model operates at slightly higher frequency range.
As you know, the version with 8 GB of memory GPU has a base frequency of 1575 MHz, and under load it overclocks to 1770 MHz.
The 16GB version of the card, which never went on sale, GPU worked at a frequency of 1590 to 1800 MHz.Cards differed not only the volume, but also the standard of video memory.
Unreleased model used less efficient GDDR6 instead of faster GDDR6X memory.
The GeForce RTX 3070 Ti 8GB model uses a 256-bit memory interface and GDDR6X chips with 19Gbps per pin.
This provides a memory bandwidth of 608 GB/s.
The model with 16 GB of memory was supposed to get GDDR6 chips with 16 Gbit/s per pin, 256-bit bus support and 512 GB/s of memory bandwidth.Unfortunately, the insider did not share the performance data of the GeForce RTX 3070 Ti 16GB.
However, the fact that the gas pedal supports the current versions of the NVIDIA graphics driver gives hope that this information will eventually be published.

Bloggers showed a prototype GeForce RTX 4090 from EVGA, which will never be released again

EVGA left the graphics card market in September due to a disagreement with NVIDIA, refusing to release new GeForce RTX 40-series products.
However, before making that decision, the manufacturer assembled several prototype GeForce RTX 4090 graphics cards for testing.
Some of these gas pedals fell into the hands of popular technobloggers.One of those who received an early engineering sample of EVGA GeForce RTX 4090 in his collection of graphics gas pedals was JayzTwoCents.
According to its status, the graphics card doesn't even have an official name.
Instead of GeForce RTX 4090, the manufacturer used the \"Next Gen Graphics\" label.
Blogger shared his impressions about the unreleased video card in his latest video.The first thing he noted is a very compact for the non-reference version of the size of the prototype GeForce RTX 4090 from EVGA.
He compared it to the ASUS GeForce RTX 4090 ROG Strix and pointed out that many other vendors' GeForce RTX 4090 prototypes look more compact compared to the latter.

The new card has a larger cooling system with a more massive radiator and tighter arrangement of the ribs, as well as larger diameter fans.

A distinctive feature of the EVGA GeForce RTX 4090 was supposed to be a 12+4 pin power connector located on the back end of the gas pedal.
Such location of the connector allows to provide enough space for proper positioning of the cable and power adapter from four 8-pin to one 12+4-pin 12VHPWR connector, which has been questioned a lot lately.
Unfortunately, so far none of the manufacturers of GeForce RTX 4090 has placed the connector on the end.
The power connector is usually located at the top of the graphics card, which leaves very little space for cable routing, which in this case is very close to the wall of the PC case.The prototype EVGA GeForce RTX 4090 turned out to be fully operational.
It is based on a qualification sample of the AD102 graphics processor.
The card can even be controlled via EVGA's proprietary Precision software.
Image source: YouTube / JayzTwoCentsSome features, however, were still unavailable here.
For example, the software did not allow to increase the power consumption indicator for more efficient manual overclocking.
Despite this, even with the standard power settings the blogger was able to overclock the graphics processor of the video card to a frequency above 3.0 GHz at the standard 2520 MHz, as well as to experiment with the GDDR6X memory frequency settings.Steve Burke from the YouTube channel GamersNexus also received an EVGA GeForce RTX 4090 prototype for review.
His interest was primarily in taking the graphics card apart.
Steve showed that the solution from EVGA had to be equipped with a very reinforced VRM power subsystem.
Disassembling the card also revealed that its cooling system included a large radiator with a large evaporation chamber and seven 8mm diameter heat pipes.

Kioxia has created the world's first working prototype 2TB microSDXC card

Kioxia has announced the world's first working prototype 2TB microSDXC memory card.
The prototype was built with BiCS FLASH 3D flash memory and an in-house developed controller, and is the highest capacity permitted by the standard.
More than a decade after the SD Association released the SDXC card specification, no SDXC cards have been produced to date with capacities up to 2TB.
Kioxia's prototypes are based on 16 memory chips of 1TB, with a maximum thickness of 0.8mm in the mount area, making them a good choice for high-capacity storage.
The company expects to launch mass production of microSDXC cards with 2TB capacity as early as 2023.
Approximate retail price has not been announced yet.

MSI has taken a cue from Gigabyte and makes its motherboard with connectors on the inside out

It looks like Gigabyte has set a new trend with its Project Stealth components with ports \"inside out\".
MSI is developing a Project Zero motherboard for Alder Lake processors with all connectors for cables moved to the back side.Image source: VideoCardzThe motherboard for Project Zero is the MSI MEG Unify, most likely based on the Intel Z690 chipset.
The company decided to move the board's connectors for SATA drives, 24-pin power cable, EPS connectors for CPU power and at least one of the USB connectors.

Image source: Twitter / @g01d3nm4ng0It's very likely that the bottom USB connectors and other ports for the front of the case have also been moved to the back of the motherboard.
The angle of the published photos of Project Zero doesn't allow us to establish exactly, but now the places where the USB and front panel connectors are usually placed are covered by the casing.
MSI Project Zero Whether MSI plans to put a similar motherboard on the market, as Gigabyte has decided to do, is still unknown.
Note that use of back-to-back connector cards also requires rethinking computer chassis design.
Gigabyte has solved this issue by upgrading its Aorus C300G case.
At the same time, the company believes that placing power wires on the inside of the motherboard not only improves the aesthetics of the final assembly, but also improves air circulation within the system.
