#1 30 series

Post by SolidAir79 » Sun Sep 06, 2020 5:54 pm

I'm looking at getting the rtx 3080 and wondering if any projects would justify me getting the 3090 with 24gb of ddr6x?

Before you buy, check the GPU project forums and see if their apps will run on it. Took a while for Turing GPU support on some projects.

I am also thinking about getting one, but scole is correct. I like that the 3090 will be twice as fast as the 2080 ti.

Anyone concerned about cooling with the Founders Edition? You've seen how the cooler works, right?

Should be okay with a clc front rad and a top and rear exhaust but will see when GN does there tests

I may beg the wife for a 3080 hybrid cooled for my birthday and another for Christmas. The 1080s just ain't what they used to be

Sounds good.

Be cautious about expectations about performance compared to the 20 series. For the RTX 3080 I saw Single Precision/FP32 performance listed at 25 TFLOPs and my eyes bugged out but according to JPM, SETI.USA's resident hardware guru...
RTX 3090 $1500 24GB VRAM 10,496 cores - ? TFLOPS - 350W
RTX 3080 $700 10GB VRAM 8,704 cores - ? TFLOPS - 320W
RTX 3070 $500 10GB VRAM 5,888 cores - ? TFLOPS - 220W

I've left the TFLOPS out because I've heard the CCs are now single issue instead of double. If true, the 3090 would be just under 15 TFLOPS, if not almost 30 TFLOPS. Need to look into it further
M'kay i believe i have it figured out. What I believe they did was added a second vector float ALU pipeline that shares the same register space and execution control flow. Yes, you can say they have doubled the core count but you should also consider that they are "less capable" cores. Similar to what AMD pulled off with bulldozer cpus. And got sued over.

Basically, each core can do FP+INT at the same time, just like the 2000 series. But it can also now do FP+FP instead. However, when it does FP+INT at the same time, the total TFLOPS are cut in half. *sigh* always with the shady gimmicks

I like my reliable 1080 ti's, however the urge to update to 30's is gaining strength, lol. They will be out next month?

The 30 series is shining, but it's raining in my wallet... -besides, have you seen the 'typical board power' of the 30 series models shown so far? Example leads to the RTX 3090, 350 Watt...

sigh, if only I could swap used race tyres for GPU's …… I'd need a direct connection to the national grid :D and be within spitting distance of a nuclear power plant :ugeek:

Per JPM...
Many of them that didn't do so well in the silicon lottery are crashing, artifacting, freezing up, blackscreening, etc. Because of that, GPU makers will start issuing new BIOS versions that downclock the GPUs so they'll work properly. Of course this means crunching perf will also drop. Not sure yet by how much.

I will be eagerly awaiting for your report.
