What is the real memory speed of my graphics card?

[NDRE28]

Hello! 

I purchased the following used graphics card: Nvidia Asus GeForce CERBERUS-GTX1050TI-A4G (4GB GDDR5).

 

The official specs say that this graphics card’s memory runs at 7008MHz, but in GPU-Z I see only 1752MHz. That’s just a quarter of the advertised speed! 

Am I missing something here? 

 

What is the real speed of this memory?

Well DDR memory is for a start Dual Data Rate. So at least double the frequency.

GPU-Z reports the speed of the memory devices, which is 1/4 the advertised speed. It's fine.

That 

  

It''s about 25Mhz "too low" - 4x1750 = 6900

But the difference is marginal in performance.

Might want to check that math

Ay carramba... I even calculated with W10 calculator. How is it even possible?

1750 x 4 is of course 7000

I must have entered 1725

GDDR performs 4 operations per clock cycle. The operating frequency is 1750 MHz and the transfer rate is 7000 MT/s, often labeled as "7000 MHz effective".

Thank you guys. 

Now I understand, GDDR ain’t as DDR, to see frequency/2, but it’s frequency/4.
