Re: Goodbye Vega 56 at MSRP

I also tend to think that monitors are an investment where as video cards are more of a commodity. I'll do a mid-range video card every *2 years or so instead of spending 3 times that (or more) on the top tier video card at that time. Better still, I've tended toward great buys around Black Friday ...

Re: Goodbye Vega 56 at MSRP

Where I live, Vega RX 64 is surprisingly very available, but at the same price as the 1080. There don't seem to be any shortages at all. The RX 56 is nowhere in sight.

Re: Goodbye Vega 56 at MSRP

Hello. Since the initial discussion concerned the prowess of Vega 56 as a mining card and the corresponding effect on prices, I would add that recent efforts with appropriate tuning seem to put Vega at a similar or higher perf/W than the best RX 580/480 cards out there. It hits ~44MH/s, which is the...

If you're going to hand tweak your cards, though, it would seem to make sense to either lower the voltage on the 1070 (for similar performance) or overclock the 1070 for another 10+% per...

Re: Vega Meta Analysis

Vega has unfortunately been tested with the "balanced" (lol) profile. Simply putting it on "powersave" massively reduces power consumption with only a few percent performance loss. In my book, the Vega 56 is practically equivalent to the 1070 in power/perf with much better compu...

Re: 64Gigs Ram, 8x8 or 4x16? Threadripper

RAM prices will inevitably go down from their current (high) levels and it will probably be much more attractive to upgrade to 128GB in the not-so-distant future. In that case, you should get 4x16 GB. Performance will probably be a bit better with 8x8 GB, since 16GB dimms are very likely to be dual ...

Re: Will high GPU prices kill off PC gaming?

"High end" has always required a non-trivial cash outlay. What's different today is that more of the cost of a high-end gaming rig is in the GPU, as opposed to other system components. I don't think overall system cost has changed much in roughly 2 decades. I would also add the peripheral...

Yeah the RX 580 seems like a bad buy given the power consumption and only ho-hum performance increase. Hopefully AMD will offer something more worthwhile in the mid-range soon. If you find it at nice price, underclock/undervolt is trivial. The chip will certainly run at ~150W, if you want it to. So...
