It is curious how despite the fact that AMD has already presented three products with its flagship GPU for laptops and desktops with its Navi 23 chip, it now rectifies for desktop and specifies a feature that seemed clear: the ROPs. The Radeon PRO W6600 It gave us some good information on what we can expect from its common gaming version, but all the remaining estimates that were not disclosed of the chip have been on track except for the so-called ROPs. Why has AMD changed third?
AMD RX 6600 XT, better GPU than expected?
The Navi 23 chip that will give life to the two named GPUs will finally arrive with up to 32 compute units or CUs, which is a surprise because as we saw with the new generation consoles the maximum count, Radeon PRO W6600 included, was like maximum of 28.
This opens the door to a new chip or at least two new variants of it. The initials speak of a chip with 11.1 trillion transistors on 237 mm2, so it is really compact. As we say, it would have up to 32 CUs in its maximum configuration and this would imply 2048 Shaders and 128 TMUs, but when we get to the ROPs, surprises jump.
The initial configuration of the chip speaks of 32 units, but AMD has just confirmed that they will arrive until 64, which means that it will have the same as the chip immediately higher in range such as Navi 22 in the RX 6700 XT. What does this imply? Well, not only will the performance be better than expected, but neither the efficiency nor the consumption nor the frequency will be altered.
Up to 2.9 GHz, with 100 watts of TDP?
The first data taken from the mathematical calculations knowing the shaders and the supposed exorbitant frequency show a performance in FP32 of no less than 10 TFLOPS. And it is that 64 ROPs They do not seem to affect the frequency that this Navi 23 chip is capable of reaching, so again the figure of up to 2.9 GHz in Boost mode for this RX 6600 XT, the highest frequency ever recorded on a stock GPU.
What about actual and non-theoretical performance? Well, little is known, since AMD is being really hermetic with this, but it is estimated that it is very tight compared to the NVIDIA RTX 3060 Ti, therefore including 64 ROPS instead of 32 and raising the frequencies to the limit of the efficiency. There is less than a month left for us to get out of doubt, so we will be attentive to the most anticipated GPU within the RX 6000 series from AMD for gaming. Will it meet expectations?
