nVidia 3080 reviews thread

OK, so I respond discussing architectural differences between Turing and Ampere and you respond with condescending tone... got it. I'm done here.

nVidia 3080 reviews thread

The difficulty for AMD is that usually they get a new process node or increase TDP to get some performance, but I don't think that they can double the 5700XT TDP of 225 watts and call it a day. That should impact their linear scaling. They will need to spend transistors or reduce clock speed...

nVidia 3080 reviews thread

Looking just at compute: RTX 3080 needs to run its INTs on cores which are also full fledged FP32 cores. Per your claim, out of 136 instructions, 100 of them are FP, or 73%. Therefore, in a typical workload, you would expect an Ampere design which has the same amount of theoretical Teraflops...

nVidia 3080 reviews thread

How do you know this isn't impactful? On Ampere, an INT costs you an FP instruction. Turing had dedicated underused INT cores, so INT instructions didn't cost anything (expect power consumption and bandwidth).

nVidia 3080 reviews thread

The best way to explain the new cores is that Turing had separate FP32-only and INT32-only cores while Ampere has FP32-only cores and cores which can do either INT32 or FP32 (lets say hybrid). Although this is an oversimplification, It is a little more complicated than this (Turing INT cores...

This is what I want to see as well. I previously used a system which drew ~400 watts from the wall while gaming. That was a while ago with a 7970 and first-gen Core i7 with OC. With a 320 watt GPU, 150 watt OC CPU, and power supply (in)efficiencies, 3080 / 9900k OC rigs could put 500-550...

nVidia blog post: high FPS/refresh gives you the edge

I agree with playing better at higher framerates. What nVidia doesn't mention is the most competitive players using low/medium settings to both achieve higher frame rates as well as remove visual noise.

Question What happened to Real Time Strategy Games?

One thing which I think hurts RTS games is the multiplayer. In shooter you can play with better players than you and have fun and sometimes get hits in even if you know they will win most of the time. In RTS, multiplayer tends to be one-on-one and tends to be an APM battle when the more...

Review AMD Radeon VII review and availability thread

What he said makes a lot of sense. From a marketing perspective, AMD would not release this card if they planned to also release another card in the same price or performance bracket in the near term (next 6 months). If the most die-hard AMD enthusiasts pay $700 now, only for AMD to release...

Review AMD Radeon VII review and availability thread

Regarding the ROP count in Radeon VII, this is a limitation of all existing GCN cards which is that 64 ROPs is the maximum. This is an issue because at 1800 Mhz, the ROPs can only generate ~429 GB/s of data. Most of the bandwidth of the RVII is not needed to feed this few ROPs. nVidia does a...

Question GTX 1060 in my Dell Optiplex 9020?

The card itself will use 10 amps from one of the 12V rails (12 amps x 12 volts = 120 watts). I would say that this has a low chance of working. You can disregards 12VSB (that is standby power). You would basically need to make sure that all of your devices are on one rail and put the GTX...

I have an AMD Ryzen system with a 32 GB optane memory in the m.2 slot acting as my pagefile. The optane memory and optane SSDs are both limited to PCIe 3.0 x2 speeds, so they are quite a bit slower than RAM. In general the smaller optane memories aren't much slower than optane SSDs because the...

The capacitors should only fail on monitors made during the "capacitor plague" period of late 90s through early 2000s. If you don't have the bad series of capacitors, the most common issue on earlier series of LCD monitors is backlight failure. A backlight should be good for 10,000-30,000...

Although power should scale at the square of voltage and linearly with clock, for my 75% more power calculation I was using P = I V. 78 amps x 1.162 volts = 90 watts at 4 Ghz 115 amps at 1.381 volts = 159 watts at 4.2 Ghz 159 / 90 ~ +75%

Per Gamer's Nexus data, going from 4.0 Ghz (78 amps at 1.162 volts) to 4.2 Ghz (115 amps at 1.381 volts) requires 75% more power for a 5% frequency increase. So yes, each extra 100Mhz past ~4 Ghz is that bad. Also, 4.7 ghz is just completely not possible on Ryzen 2000 without sub-ambient cooling.

It does go higher by about 100 mhz. These clock speeds and voltages are well out of the efficient range so the last 100 mhz costs 20-30% more power draw. Power increases linearly with frequency and at the square of the voltage increase. Ryzen requires more than a linear voltage increase above...
