The graphics card market allows large companies to make certain changes from time to time that, initially, could benefit both buyers and the company developing them. In this case, Nvidia sold a series of graphics cards RTX4070 which instead of including the AD104 chip, the base chip of these GPUs, includes a more powerful one, the AD103 used in the RTX4080but with reduced power to adapt it to the mid-range version.
Being one of the leading companies in the information technology sector, Nvidia has carried out a large number of projects which have allowed it to remain commercially at the forefront of the world’s largest companies. But this does not mean that they must sometimes adapt some of their technologies for other uses, as is the case for some RTX4070 which integrate a much more powerful chip than they should, even if obviously this power is deliberately limited.
Some RTX 4070s include the RTX 4080 chip
In the GPU market, Nvidia is a company that offers a large number of ranges, which allow users to choose the power according to their budget. In most cases, each graphics card usually has a specific chip designed that, depending on its cost, reduces or increases the power. . In the case of RTX4070incorporate the AD104 chip, a version of the chips created by Nvidia whose memory-related specifications are 12 GB, GDDR6X, 192-bit.
On the other hand, the RTX4080 They include a higher version of this chip, which allows for a larger amount of memory as well as an increase in the clock speed itself and the Shaders, TMU and ROP. This is why it is strange to see how it is used in other low-end graphics cards that offer much lower power than the 4080, as in others that can offer similar performance (and price) , it is not strange to find this chip. , for example, the 4070 Ti Super also incorporates this chip due to the technical limitations of the previous one.
On the other hand, what is strange is that they use it in a much simpler way, in low-end graphics like RTX4070 more basic, knowing that to incorporate it they must reduce practically all the technical aspects that make up the chip RTX4080 on a titan. This implies that they adapted the AD103 chip so that it could be used with the 12 GB format of the 4070, reducing the memory bus to 192 bits from the 256 it supports, as well as other aspects like throttling Shaders and L2 cache. , thus reducing the power of the graph.
Why would they include a superior chip in an inferior GPU?
The investigation was carried out by Techpowerup, from where they indicate that a user of their page told them that the program they created to find out the specifications of graphics cards, GPU-Z, was not capable of identify their video card. This led them to begin investigating the reason that could be causing this, discovering after several tests that it was a RTX4070 which incorporated a chip from RTX4080 with limitations in terms of performance and power.
There is no conclusion as to the real reason why Nvidia I would try to incorporate this chip into graphics cards, as they should have a large enough stock of AD104 chips to be able to make new graphics cards. RTX4070.
