Really? Find any cheap RX580s recently?
Not if you can't buy one for 6 months. 1080ti arriving tomorrow.
it is 4-6% inferior to gtx 1080, and about 23% inferior to gtx 1080ti. it just came out and someone has already did the test, WHILE BEING MORE EXPENSIVE THAN BOTH.
not a typo. rx vega got smashed. it is inferior to gtx 1080ti while being more expensive. 23% inferior performance is too much tbh.
rx vega 64 just got smashed. it is just about equal to gtx 1080, while being so much more expensive. GTX 1080 TI is about 23% better than this shit vega while being even cheaper.
your rx vega 64 got smashed. it is just about equal to gtx 1080, while being so much more expensive
You want AMD For Rendering.
cough mining cough khe khe
Why don't you wanna see AMD win? They have cheap GPUs that perform well. They're the good guys here.
Tks my friend. For the price, then compensatory a Vega.
Ever since the 3Dfx Voodoo 2 we know that you get the best results with a ROP for every 2 TMUs, not 4 TMUs. If only AMD released a Vega with 128 ROPs, that would be great. Is it too much to ask? Sure, compute performance is definitely there even today, but the gaming performance depends on ROPs with pipelines as short as possible, but able to handle the clock speed.
Which is bs because more modules improves the throughput, not the latency. It's more like "effective bus-width" that increases with more modules.
That bus though! I'm definitely looking forward to the Rx Vega 64
The technology uses everything so it can push more power. Its like a 8GB HBM2 has a similiar power as a 16GB DDR5 module. No gaming trought because this GPU should be used for professional use as rendering of videos... I mean for business use.
AMD Vega is made to look too good here, wait for benchmarks to come out. It is slightly faster than a 1080 but slower than a 1080 Ti.
Can anyone translate me this data up to me: What is best to do the rendering in vray sketchup?
AMD will come with a cheaper price, as always. So the competition is still on
So what, AMD finally came close to making something similar to the 1080 TI and its still barely better? If i remember correctly, when GeForce release the 1080 it was times better than the old products, which was a huge step-up, meanwhile AMD is barely able to keep up it seems.
It's probably from all memory modules combined ;) just like my old hd7850, memory clock 1250mhz but it has four memory modules so effective memory speed is 5000mhz
I doubt it's got clock speed of 11,008 MHz Definitely a typo... ;)
HBM2 use a different technology but think about raw data and see this memory bus AMD 2,048 bit vs Nvidia 352 bit, but memory clock speed AMD 1,890 Mhz vs Nvidia11,008 MHz simple math here: AMD 2048x1890=3,870,720 bits vs Nvidia 352x11008=3,874,816 bits that is a 0.1057% in data transfer different on paper and in theory HBM2 technology offers some better performance if used in the right way especially in case of sli/crossfire kind of scenario.
Vega uses new HBM2 memory thus the difference as it is different technology.
Yeah, what happened there?
The memory diference is so vast
