InVasManiI'd like to see the AIO's with

freeagentIts funny how things that were old come back in fashion again :)

Rigs that can pull 800w+ at the wall might be commonplace again.

freeagentThe last time I was able to pull 800w at the wall was with X5690 and GTX 570 SLi all running F@H.

Thats full load, not even playing a game :D

PumperPCWorld has some ECO mode tests. It looks like Intel is losing way more performance when you limit the watts, i.e. 105W 7950X (10% loss) vs 105W 13900K (25% loss), but the actual measured system power consumption is ~40W lower on the 13900K.

I guess AMD's ECO modes don't really limit the TDP to 105W or 65W (that is the case with my 3900X as well, as when set to 95W ECO mode with -0.1c, the CPU is still using ~124W at full load, while in normal more with -0.1v it's using 128W).

freeagentI would like to see an AIO that is basically a small custom loop where you have a quality rad and pump that has real capacity and can be refilled. I know you can buy kits but who wants to spend 500 to cool a component?

zlobbyNvidia got you covered, fam!

ValantarI mean, to be fair, 300W is still a pretty weak space heater. 750W together with that GPU and you're getting somewhere though! OC both and you'd probably hit 1kW.

TomgangWith bofh system at peak. I think i can now pull more what my 1200 Watt PSU can deliver in the long run. Maybe for peak it can go, but for constant load, i think there is risk of overload. Hence why i now needs to be careful when bofh system runs a full tilt at trhe same time.

ValantarOnly if that PSU is pretty terrible quality. ATX (electrical, not form factor) PSUs are rated for continuous output, not peak. A 1200W PSU, given adequate cooling, should be able to deliver 1200W output constantly until its MTBF (or thereabouts). Most can deliver noticeably more than their rating (OCP is often +20-30%), but at that point you're stressing components in a way that will promote premature failure. Of course a less stressed PSU will last longer, that's a given, but we're long past the era of garbage PSUs that can only reach their rated power for a fraction of a second before blowing up.

TomgangROLF. they sure does have me covered for heating and gaming i see.

dirtyferretDon't worry Lenne, Intel has you covered

yeeeemanstop spreading BS info from hub. you have techpowerup...efficiency of 13900K is very good, similar to 7950x at lower tdps.

WarigatorOther sources tell a completely different story (for example Hardware Unboxed), that the 7950X is much more efficient than the 13900K.

zlobbyEfficiency goes into the drain at max power.

zlobbyThe rated power is the maximum power, not the nominal one.

zlobbyPlus, 1200W is a SERIOUS power. Select few components can withstand 24/7 work under such loads, let alone for years.

WarigatorI remember overclocking Core 2 Duo from 1.8 to 3 GHz. Now we are overclocking 5.8 to 6.0 GHz? Doesn't seem impressive to me.


I agree. Both 13900K and 7950X efficiency after underclock, tuning and power limiting is about the same, at for example both limited to 90 watts... according to one source. Other sources tell a completely different story (for example Hardware Unboxed), that the 7950X is much more efficient than the 13900K.

Valantar... and a PSU rated for that output thus needs components capable of handling that output.

ValantarIt's lower than at lower outputs, yes, but down the drain? No. Most modern PSU designs lose a few percentage points of efficiency between peak efficiency and 100% load.

No, rated power is peak continuous output.

... and a PSU rated for that output thus needs components capable of handling that output. Sufficient cooling to keep them operating within spec is obviously a necessity, but these components are rated for sustained loads.

Chrispy_Auto OC to 6GHz is going to be hillarious.
I wonder how many people will RMA their boards because their socket melted.



You see how it flatlines past 300W and adding more power results in next to nothing? Yeah reaching 6GHz is going to be a 500W job, most likely.

So, if you extrapolate the CB R23 results, a 6GHz OC might get the 13900K 40,750 points. Meanwhile, a 7950X is getting 94% at likely just one third the power draw. It may no longer be the fastest consumer CPU, but the 7950X sure as hell is a better CPU for consumers. For a 6GHz 13900K you're going to need a custom loop with two large radiators, a high-flow CPU block, oversized tubing throughout, and a powerful pump, if not two pumps in series. Suddenly the cost of the CPU and motherboard are irrelevant because you need to spend $1500 and a few days of your time on the cooling alone.

fluxc0d3rI heard to reach that speed you need to buy one of their supporting Gigabyte PSUs.
