History with frequencies (!) GPU GeForce 7800 GTX
First, let’s show a screenshot from the driver’s control panel, which declares the nominal frequency in 3D for a card based on G70 from Gainward:
As we can see, everything is “chin-chinarem”, the frequencies are as promised – 470/1300 MHz. However, even when testing the reference card, I turned
attention to the fact that RivaTuner monitoring (by A.Nikolaychuk AKA Unwinder) showed a slightly different frequency, about 40 MHz higher than the nominal,
(reference frequency – 430 MHz + 40 = 470 MHz). The fact is that at that time the utility determined the maximum
the value that clocking gets.
Together with the author of the program, we began to figure it out, testing the card literally with a step of 5 MHz above and below the nominal, constantly removing the report
from chip registers. And they found out that the frequencies there, in fact, are already THREE PIECES. Now there is information on the Web that NVIDIA is on the backstage
talks about a larger number of frequency values, that the entire GPU consists of many blocks, and each block can potentially work on
its frequency. And it becomes already incomprehensible – and which of them then to take for the basic one, what to write on the boxes, etc.P. It is logical
taking for such a frequency of the rasterization unit, pixel pipelines, however, and this unit is not unique. Now there is ROP, and there is a Shader unit.
In general, this issue is still unclear, but since today the frequencies of BOTH these sub-blocks are equal, it is this frequency that is taken as a basis.
And it is it that is declared as 430 MHz for the reference card and 470 MHz for a specific card from Gainward.
And what, then, is that frequency increased by 40 MHz, which I mentioned above?? – This is a geometry block clocking. And since today
it consists of vertex pipelines, then we say that Vertex pipes operate at a frequency of 470 MHz. Immediately
after the announcement of the G70, ASUS announced that its card will operate at exactly this frequency. I have not studied this product yet, but I can assume,
that marketers, having received information from technical specialists about different frequencies on the GPU, decided to use this moment, and issued exactly
the frequency of the geometric unit (470 MHz) for the main one, and their SmartDoctor utility will declare exactly this value, as the published
earlier version 15.6 RivaTuner programs. I repeat that these are only my assumptions, it may very well be that they, like Gainward, nevertheless changed
So what is the fundamental frequency. From what we looked at earlier, we realized that there are THREE blocks that can have potentially different frequencies:
ROP, Shader Unit, Vertex Unit. Alexey Nikolaychuk has already fixed all three parameters in his new version 15.7 coming soon:
Please note that in 2D mode, all three units operate at the same frequency of 275 MHz. When you turn on 3D (and this will be clearly visible
in our video in an upcoming article) the frequency rises to the level… And we look: to what. The geometric block worked clearly at the frequency set
BIOS (470 MHz), plus 40 MHz = 510 MHz. But the other two – have risen to the level of 459 MHz, but not 470.
Studies have shown that the frequencies of ROP, Shader Unit are changed, firstly, by the driver synchronously with the geometric unit, and change them separately
it is unrealistic yet (the driver will install its own anyway); secondly, they change in 27 MHz steps! There is a crystal oscillator on the card itself
27 MHz, and the driver selects the frequency of the chip by multipliers. And in this case it turns out as
27 MHz * 16/1 = 432 MHz
This is where we got the very 432 MHz (declared as 430), which are available in the reference card. Further growth of frequencies can only be
like 459, 486, 513, etc.d. MHz. These two named units cannot have any 470 MHz for today. I emphasize again: this installs the driver, and
its versions are subject to change, and therefore may be changed in future versions.
So, the driver “looks” – which of the listed frequency values is closer to what is set in the control panel (or BIOS), and sets
exactly or 432, or 459. 470 MHz is closer to 459 than to 486, which is why we see exactly 459 MHz on the monitoring. And in reality the card works for
459/1300 MHz with geometry block at 510 MHz.
Let me remind you that since the days of GeForce FX, older cards have THREE modes of operation: 3D High Power,
3D Low Power and 2D. Medium mode did not appear in the settings of NVIDIA drivers in any way, set it
it was possible only through RivaTuner.
The same three modes remain to this day. The jump to 3D Low Power occurs after exiting the 3D application.
As we can see, the transition back to 275 MHz in 2D does not occur immediately, but at first the frequency is reduced by 3-5 seconds to 418 MHz (3D Low Power). Note,
that to obtain this frequency, the driver already uses other factors:
27 MHz * 31/2 = 418.5 MHz
This suggests that the driver can potentially use different multipliers, and therefore the step of 27 MHz may remain completely, or maybe
So, we found out that today three blocks of GPU work are clearly visible, each potentially has its own operating frequency, but the driver keeps them
in batch mode, with the only exception that for a geometric block, the change step is very flexible (its own multipliers), and for ROP / Shader Units, the step
equal to 27 MHz. Within half of this step with a constant ROP / Shader Units frequency, we can change the frequency of the geometry unit.
It was also found that the operating frequency of the same Vertex Unit is rigidly higher by the same frequency value, which is set by the BIOS (+40 MHz).
The work is not finished, because, according to NVIDIA employees, there are even more than three blocks with different frequencies in the core. But it’s time to understand one thing: more to carry
it is impossible to talk about the CHIP OPERATING AT SUCH frequency. Rather, it is possible, BUT CONDITIONALLY, taking as a basis the frequency of operation or ROP, or Shader Unit,
since they have a greater impact on the final performance.
