Is it faster, yes
Does it cost more, also yes
Is it on a similar die with likely fused away CU', probably
Soo why justify one SKU over the other.
If you're gonna fight the pricetag, do it for all from the cheapest SKU onwards.
It's not too hard to focus on your full-size chip , and then scale downwards economically.
It's hard to design always the best, and be judged for it ~ but why start to cherry pick judge.
*non, XT, XTX, XTXH, KXTX
are anyways confusing handles, that don't need to exist ~ especially within the same number class.
But at the end, its usage of the yield.
One is low leakage and low power. One is low leakage, low power but lack peak clock. And then the opposite for high leakage but with defective CU's.
// 4 SKUs + 1
The KXTX one i could call milking. But wouldn't know how to separate a new revision of a product that's just 5-8% better
Yet far to slow for a new generation. You have to nail your products or not release them at all ~ when you're under tight timeframe.
I don't know, yet they don't deserve ("they are irrelevant") titles. The naming on the other hand, is pure nonsense
Eh i guess it works out somewhy
EDIT ~ Examples:
67xx ~ high leakage, high peak clock, many defects
6800 ~ Low Leakage , low peak clock, defects
6800XT ~ High leakage, variable peak clock, defects
6900
XT ~ Low leakage, low peak clock, full chip
6900
XTX ~ Low leakage, mid peak clock, full chip
6900XTX
H ~ high leakage, variable peak clock, full chip
6950
KXTX ~ low leakage, high peak clock, full chip
^ all except the 67xx are a full chip & different on Firmware (only?). The 67xx then also cut VRAM cost
The 6750 could be called
~ low leakage, high peak clock , many defects
And if we do that, the 67xx lineup is also a repurposed full chip.
But it's more complicated than that & an
LH version exists as ("mid" leakage, low peak clock, many defects)
// which could end up in a laptop but probably wasnt efficient enough and became "low harshrate cheap-gamer edition" (guess
)
Any low leakage substrate will always be more efficient, even if you match CUs
It's not a bad business to arrange your SKUs that way and keep sellable yield higher.
But absolutely is it confusing, especially since the user has to try and figure out what is high leakage & low leakage
~ ontop without any public documentations of for example how LkgID functions nor is classified as
Confusing or low terms "missleading" for the Media Field and Consumer/Prosumer field.
