What time are reviews out today?

2pm.

Sorry but as someone that spent a fair amount of time looking for 2 slot cards, 52mm is not 2 slot. ~40mm is 2 slot. It got quite annoying looking for 2 slot cards...

You're right the shroud overhangs the io plate a little, its 2.5 slot.

PULSE AMD Radeon™ RX 7800 XT 16GB

Reaper is the slimmest XT

Do we know why Asus have gone with 3x 8 pin connectors on both of their cards vs. Sapphire Pulse having 2x 8 pins (on the Pulse model)? Assuming they're both going to very similar in performance.

Better distribution of load ?
Some of the better PSUs handle 600W off 2x8pins with decent cables perfectly fine

For those with inferior cables and or with cables wired with 6 pins then 3x8pin would be better distribution

Also remember never to use those y-cables running off a single 8 pin - you will definitely be limited to 300W which is a lot of load on a single channel if the y-cable is rubbish quality

It hasn't but the prices looked very specific.

My thoughts exactly.

My be quiet 1000w PSU came with only daisy chain pcie cables, ran a 7900xtx on them (3x8pin) and it pulled 460w.

2X 8 pin = 375 watt if you include the PCIe slot its self, the 7000 series had a +15% power slider, AMD measure the total board power, not just the chip, so everything that's on the PCB, including fans and LED's, the 9070 XT has a total board power of 304 watts, + 15% = 350 watts, that's with in limits but i guess some like to add 3 so the power is more divided up.

Oh... wait, literally as i type this i remembered some partner models will be 340 watts, so + 15% = 390 watts, there you go...

the three slot pure will have better cooling than the 2.45 slot hellhound?

Yeah, that makes sense, thank you. I guess a bit like when we see B-series motherboards occasionally have 2x 8 PIN connectors!

100%, Sapphire's cooling has always been fantastic too. My 7900XT Pulse never goes above 70 deg at full beans.

 

[hornetstinger]

Prefer the black pulse, the white one is clocked slightly faster?

Do we think MSRP will be hit consistently by the Summer?

you're not getting one so what does it matter!

 

[Hostile_18]

Impossible to say. I wouldn't take anything for granted in this market. I'd buy now if you can afford to.

 

[hornetstinger]

Since you have 7800XT I'd spend it elseware. Maybe a pair of decent PC speakers

 

[gilljoy]

Depending on reviews I'll be very tempted to grab a XT to upgrade from my 3080 but gotta wait for perf.

 

[GoogalyMoogaly]

I'm thinking performance across models will be pretty similar, so the thing that interests me in reviews will be the differences in cooler performance.
Can you get away with a smaller cooler? Is there much benefit to a bigger cooler?

 

[Hostile_18]

Best check the Techpowerup reviews for thermals and acoustics compared to each other, at 2pm. No one really knows for sure yet.

Not that this should surprise anyone but here's confirmation that there will only be a limited quantity at MSRP during launch. So if you want one that cheap then get it quick otherwise you could be waiting for months for it to come back down, if it ever does.
