When I posted the PS5 Pro vs PS5 specs comparison, I told you that the former would have an extra block 2 GB of DDR5 memorya very interesting and very important fact that has just been confirmed by a leaked image that shows the spec list of Sony’s new console.

That 2GB block of DDR5 memory shouldn’t surprise anyone. Sony has already included the block 1GB DDR3 on PS4 Pro which was reserved for the operating system and applications, allowing the Japanese company to free up a bit more GDDR5 memory to devote to games. This was necessary so that the PS4 Pro could perform better at higher resolutions.

The case of the PS5 Pro is absolutely identical, as those extra 2 GB of DDR5 have been reserved for the operating system and core applications as well, allowing Sony to free up more GDDR6 memory. It’s not yet confirmed how much GDDR6 memory will be available for games, but the latest information I’ve seen has pointed to 1.2GB more for free.

How the PS5 Pro’s performance will improve with that extra 2GB of DDR5

We have to keep in mind that although the PS5 Pro will also have more free GDDR6 memory it consumes more memory of this type for two things, to handle the higher base resolution and higher graphic settings, and also for the PSSR to work normally, since this technology needs to create a buffer to work, and it takes up part of the GDDR6 memory.

Increasing the resolution will increase memory consumption and the same thing will happen while using better textures and shadows. Finally, the extra amount of GDDR6 memory that will be free in the PS5 Pro will be used so that the console can better cover all those queues that I just explained to you and not have the performance problems that would occur. if available memory is insufficient.

I know 1.2 GB of GDDR6 may seem like a little, but it is enough to make a significant difference. Keep in mind that PSSR theoretically consumes an additional 250MB to run, and that simply increasing texture quality can easily add up to an additional 512MB. By adding the resolution increase, we would already exceed one gigabyte of consumption.

The list of specifications also includes other important information about this new console, such as a direct reference to the performance of its GPU, which is 16.7 TFLOPs in FP32and on the maximum total system consumption that will be 390 wattswhich is a figure slightly above the PS5’s maximum 350 watts.
