Duda about CUDA cores
-
Hello, I am going to buy a graphics card in a few days and I am between two, the gtx 660 and the gtx660 ti, the difference apart from the price is the number of cuda cores, I have searched the internet for what that is but it is not clear to me, nor whether the gtx660 ti that has more is worth it, I have been told about the R9 270X dual-x 2gb, and now I do not know which one to choose from the 3.

hello, well don't bother yourself so much and buy a Gigabyte GeForce GTX 760 OC 2GB GDDR5 239 euros approx
if your budget allows, of course, how much can you spend?
regards

well now I don't have enough, I would have to wait a few months, I've looked at the features of the r9 270x and it's not so bad, apart from the card I have to renew the power supply and in a few months buy a printer, in the end I don't know what I'll do.

The R9 270x is equivalent to a GTX 660 (it is nothing more than a rebranded HD7870) and inferior to the GTX 660 Ti which is closer to the HD7950. The level of performance you want is well covered by the GTX 660 if you think the 270X "is not so bad" (same levels of performance). If you want more you have to move to a GTX 660 Ti/760 or an HD7950, but not in the world is the 270x similar to the 660 Ti.

I've seen the hd 7950 and it's already in the drum, is the cuda thing that nvidia has important? I don't know what it's for or if I'll ever need it. If I have to choose between the gtx 760 and the hd 7950, I'll go with the latter, which is cheaper even though in several stores the difference is more than 50€. -

I have already read that article, I have read it again but I still do not know if ATI or NVIDIA is better for me, well maybe I can buy the HD 7950.

Wikipedia explains that it is a way to allow programmers to use the GPU in their programs for parallel computing. In the final links you will find the NVidia website where you can see which applications use it.

If I were you, I would go for a GTX 760, it's worth spending a little more so that you can have some extra power for gaming (if that's what you're going to use it for), of course, if you have the money, I've tried both ATI and NVIDIA and I can tell you that both perform well, it's just a matter of taste as to which model you choose, I think NVIDIA is better.

The cuda cores is how nvidia calls its shaders, AMD calls them stream processors, so they can be decisive or not, there are games that you can notice more cuda cores, but the chip influences, the 660Ti has the same cuda as a 670 and the same chip ie GK104, but the 670 performs better as it has 256 bits, compared to the 192 of the 660Ti.
The 660TI is better than the 660 not only for the SP or cuda, but for being a GK104 compared to a GK106, but they are graphics that have little bandwidth both, and for example a 760 with less cuda than the 660ti and 256bits usually performs a bit better, that's why in the end what matters is the performance in the games you use, normally there isn't much difference.
Right now the 660ti if you don't see a good offer I don't see it as recommendable, it's better to have a 760 and also with 256bits it takes better advantage of the 2Gb of memory, even the 760 goes up more, although it's also expensive given that there are 660 for less than 150€.
it's that at this price I prefer the 660 rather than 7950 and 760 or 660Ti and I'll upgrade sooner within a year or two

Yes, it's true that this is what SPs are called, but as you said, it's something particular to each GPU. You have the 760-770 and the 780-Titan, which are different architectures (and are superior to the previous 6xx generations), but normally the shaders go according to the potential of the graphics card, it's not something you can choose freely. The most important thing is to see the performance it gives within the game, which you can't always determine by looking at the technical data of speed and number of processors.
PD. The 660ti is not bad at all, but if I were to go to NVIDIA, I would also prefer the 760. In ATI, I would wait to see the new releases.

Yes, it's true that they go according to the potential of the graphics, but other things also influence, I was referring more to the 660Ti that if it's a GK104 and has quite a few more SPs than the 660, even more than the 760, but in the end, one for bandwidth and frequency manages to perform a little more, the 660 is an inferior chip but compensates for it in price, the 660Ti will get 20% at most to the 660, I mean on average.
But it is better to focus on the games and the differences between cards more than on the specifications, because there are variants like the 760 and 660Ti that despite having fewer SPs, the 760 performs a little better for coming to more frequency, having more ROPs and better bandwidth, it's more complicated to compare just by specifications.
I also think it's better to see what AMD brings out, although for now the R9 280 hasn't come out, nor the 270, only the X series, but it's possible that they cost less than the 7950 and very possible that they will lower the price of the 760 and 770.

well I almost go with this one, good cooling and very good performance

Ehhh… no. It's going to be that it's not. The GTX 700s less the GTX 780 are, literally, the same architecture and same GPUs as those seen in the GTX 600s, but exactly. For lack of not there is no difference of a new stepping of the GK104 or anything that can be blamed on them to say they are "different" much less "superior".
What sí, are different models from the ones that already exist, the GTX 770 is basically a GTX 680 boosted and better assembled in PCB and faster memory chips, and the GTX 760 is at the same time a GTX 670 "LE" but boosted in frequency and voltage, which makes up for a lot with the frequency the SMX disabled it has compared to the GTX 670s.
But except for the GTX 780, the others are the same type of chips mounted as in the GTX 600s. And in fact the GTX 780 is not a new architecture or remodeled, it's the "daddy" of the kepler remodeled (GK100->GK110) that came out first for Tesla cards at the end of last year, and in this as a Geforce first with the Titan and the Ultra. But de facto it was the first chip they were working on from kepler, along with the GK104 very closely.

It's what I said, that 760 and 770 are different from 780 and Titan, although they are all the ninth generation 700 and in each range they perform better than the previous one... I just said it so as not to put them all in the same bag, I didn't want to go on with an explanation that I wouldn't understand.Sent from my GT-I9505 using Tapatalk now Free

so how do you see the hd 7950? -
