GPU prices go boom

[andybird123]

Glad someone noticed.

We did not need to drop the 1080Ti Strix OC to £749 to give our loyal customers a chance to grab one. The simple fact is we could have left them at £1000 and still sold them all.

and props to you for doing it, the only reason it came up was that someone suggested the £999 price was 8% margin, which clearly is not what you said in that thread

 

[Hopper-]

Glad someone noticed.

Ill take 7 570's next week

 

[MooMoo444]

That 1080 Ti deal was cracking. I'm gutted I didn't have the opportunity at the time!

I wonder how many people bought it just to resell though..

 

[Hopper-]

There are other retailers that do very similar pricing however stock is very flakey unless you have some sort of automated bot enabled to ping when stock is seen

I dont know, but surely at £750 any miner paying more than that is a bit silly. ROI will be non existent.

No the top end ones had more shaders unlocked - 112 (GT) v 128 (GTX) shaders - the G92(B) GTX cards still has the 128 as per G80 GTX.

They were all the same core but the GT cards were salvaged cores with 2 SMs fused off reusing cores with 1 or 2 failed SMs.

G92 were cut down cores in several respects and relying a lot on clock speed to make that up - for the upper mid-range/lower high end cards it actually worked out pretty well but it resulted in the top end cards being a bit lack lustre.

Sorry, I should have expanded that last sentence, since I explained about the shaders and ROPS and memory bandwidth earlier in my post, I didn't think I would have to point out those differences again.

But, they are essentially the same chip. They are all cut down versions of the G80 with higher clocks. The die shrink let them achieve higher clock speeds. The 9800GTX has fewer ROPs which account for the performance difference that clock speed couldn't completely catch up on, it took a further die shrink to beat the 8800 GTX.

To put it another way, as an example, the 980 and 970 are the same chip, just one is a cut down version of the other.

Just in case you think I am arguing with you, I am not, I agree with what you are saying.
​

Not sure I'd entirely agree with that comparison - G80 to G92 was more like Maxwell 1 to 2 or maybe Kepler to Maxwell (though there are some reasonably significant shader enhancements there) - Maxwell to Pascal sees some fair architectural enhancements especially when it comes to threading and memory atomics (and memory handling in general).

This. Maxwell to Pascal was a significant change, moving from planar to Finfet along with architecture changes.

Nah I explained the differences in the G80 and G92 paths on the last page:

You do realise that the 8800 GT, 9800 GT, 8800 GTS (512) 9800 GTX, 9800 GTX+ were all the same chip? They were all G92a(65nm) or G92b(55nm) They all had a 256Mb memory bus, the performance differences were down to the clock speeds and the number of shaders/rops.

And the G92 was basically just a die shrunk G80 with a hardware video decoder added.

That's why those G92 cards were so cheap, Nvidia had done all the heavy lifting with the G80.

The naming scheme is exactly as you mentioned.

No because they weren't, like I explained earlier the 8800GT and 9800GT (and OEM GTS240 variant) were all rebrands of the same chip. The 8800 GTS (512), 9800 GTX, 9800 GTX+, GTS250 and fake Chinese GTX780s were also all rebrands of the same chip. But they were two different chips using the same architecture. In addition to clock speed differences there were also shader/TMU/ROP count differences between the two chips so your assertion that they were all the same just with different clocks is false.

I.E the GTX770 was a rebrand of the GTX680, but the GTX670 was a different chip using the same architecture.

LOL sorry, the 670 and 680 and 770 were all the same chip. They were all the GK 104 chip. The 780 was the chip as the original Titan just a cut down version. (GK110) The 780 Ti and Titan blacks (and some of the later 780s) were all based on the GK110b chip.

Cutting down rops/shaders doesn't change the type of chip. More examples, the 980 and 970 same chip (GM204) The 1080 and 1070 and 1070Ti same chip (GP104)

The 8800 GT, 9800 GT, 8800 GTS, 9800 GTX+ , 9800 GTX OEM 240, 250, were all the same chip and the same architecture.

Jesus, lol.

8800GT: 112 Shaders, 56 TMUs.
9800GT: 112 Shaders, 56 TMUs.
GTS240: 112 Shaders, 56 TMUs.

8800GTS (512MB): 128 Shaders, 64 TMUs.
9800GTX: 128 Shaders, 64 TMUs.
9800GTX+: 128 Shaders, 64 TMUs.
GTS250: 128 Shaders, 64 TMUs.
dodgy Chinese GTX780s: 128 Shaders, 64 TMUs.

They are NOT all just identical chips with different clock speeds, there is a distinct difference between the chips used in the first group of rebrands and the chips used in the second group of rebrands.

Do you think the i7 8700K and i5 8600K are identical apart from clock speed?

 

[keyser]

I'd just be happy for no fan spin technology tbh. Haven't gamed for over a year. I'm looking at NAS and 12TB HDDs.. I'm on a mission on PC silencing, its getting there When the uber 4k gaming monitors arrive then I might need to upgrade gfx. No need for a new CPU until meltdown/spectre is fixed at hardware, and Intel release something worth upgrading too. I'll catchup with AAA games on future uber computer one day.

 

[Caracus2k]

They are essentially the same chips from the same processes? Intel just disables HT on one chip and sets different stock speeds.

Nvidia often also provide gpu's using the same dies as better performing parts but with some components disabled

I. E the original Titan and Titan black are based on the same die with the former just being partially disabled.

 

[ubersonic]

They are essentially the same chips from the same processes?

They are both based on the same design but feature differences that make them different not identical, I.E one has more cache. Likewise the G92 chips with 112 shaders used in one line of rebranded cards and the chips with 128 shaders used in another line of rebranded cards are different chips both based on the same design, not just the same chips with different clock speeds like he claimed.

Were they not the same chips with some just being partially disabled and later on the same chip just manufactured on a smaller process?

Same chip/die different configuration. Some times this is just controlled in the Bios (like say a old Radeon 9500/9700) but these days its done by both lazer cutting off defected area of the die to make the greater or lesser chip backed up microcode and a different bios.

Jesus LOL yourself. They are all the same chip. Just with various parts unlocked/locked depending on the market segment they were aimed at.

You first said that they 670 and 680 were different chips, they aren't. I showed you the flaw in that.

to give another example the 6970 and 6950. According to you they are different chips, because they have different ROP and Shaders. But they aren't different chips, they are the same chip. Which is why people got so excited when you could unlock the cores on the 6950 to make it perform like the 6970.

The shaders and TMU's are things that Nvidia can lock on each chip. It's why through the years people have been able use mods to unlock various cards to perform better. AMD GPUs are normally better because they don't hard lock them. Nvidia usually physically disable them.

Changing the number of TMU's and Shaders doesn't change the type of chip. It's the same chip.

Yes, this is the point I have been trying to get across.

 

[KillBoY_UK]

Yes, this is the point I have been trying to get across.

Think of it this way You the Uber Car V6 and the Uber Car V8 , they are Identical in the hardware manufactured in a identical manner just 2 valves are shut off by the engine management software all the time.

Are they different products, Yes, do they have different configurations yes, but is it a different engine under the hood No.


8800GT, 8800 GTS 512mb, 8800 GS, Quadro FX 3700, 9800 GTX, 9800 GX2, 9600 GSO, 9800 GT. They different products with different configurations but they all use the same G92 die/chip which all came from the same silicon wafer

Yes, fully agree with you. That's what I was trying to show with my example of the 6970/6950 or his example of the 680/670 and 770.
