Looks like Lunar has a better GPU than Strix at higher power levels and is the same at lower levels.
Shows a couple things, Strix is way better at low power than before, and bandwidth limits it quite early.
Also remember that Time Spy is a strong Intel bench and a weak AMD bench, so what matters is gains relative to previous generations from the same company.
Strix should be comfortably ahead in games across all TDP ranges, except for extremely membw bound games or games that just love all flavours of Vega.
wanna bet on GPD trying?
I just wanna modified Zeph for Halo, already the right form factor for it.
I do worry that Halo designs wins will all be mobile workstation focused though.

if is this is case we need to verify with steel nomad then.

Let’s see but you might be right.

Ehhh, see below.

You're right about the technical properties, but @Goop_reformed is also right about the marketing proposition. AMD is selling Zen 5 as the leader in performance, with heavy emphasis on ST.

Sort of, do you really think AMD is mentioning this in closed door meetings with OEMs and hyperscalars? No.

Where is most of the revenue associated with Zen5 going to come from? Hyperscalars and anyone else buying Turin. Plus SMT improvements will go a long way towards helping 6c and 8c Zen5 consumer parts, never mind that AMD isn't marketing that.

Ultimately whether SMT is or isn't a "selling point" for Zen5 is irrelevant. Someone comes in here and asks if Zen5 is gonna be any good, and the answer is "kinda, unless you enjoy the benefits of SMT, then definitely". It really shouldn't matter to anyone here how AMD is actually marketing the thing. What matters is what it does (or will do). That's what got us onto this tangent into the first place, is someone asking whether Zen5 is good.

You verify it with Video Games.
Yeah I know, heresy, but video games are video games.
I was referring to the fact if Time Spy is biased to Intel GPUs then we can use Steel Nomad to see the difference since both are 3D Mark tests and it will tell us if Lunar’s GPU performance is consistent.

i do agree that games are the best test but yeah was talking about the 3D mark suite.

Zen 5 doesn't exist in a vacuum, and SMT is not the selling point of the zen family. It's always been scale and future upgrade path. At the moment, when intel is catching up on the nodes and design, AMD have to find another competitive advantage, and it's single thread performance for Zen 5.

Again, WHY DOES THAT MATTER. If it's good, it's good, and if it isn't, it isn't. Or are we going to obsess over bizarre AI Turin benchmarks from AMD marketing too, when Turin isn't specifically targeting that market?

If someone comes in here and asks if a product is good, the last thing anyone should do is show them a marketing slide.

More precisely, they have to sell a harvested 1-CCD part if they want to have somewhat profitable products in those price ranges.
So until they add more cores per CCX, 6cores are to stay, sadly.
Basically, these volume parts have to be 1-CCD and they probably don't want to move octocore to R5 segment because then the R7 segment would have to be dual-CCD and that would be bad for profitability.
Some are salvaged dual CCD like mine.
Only one CCD active of course but two present under the hood.

I have a feeling that you may now be Internet famous, but that you wish you weren't. Like you said, you might not be getting any leaks for a long time now if ever. Or they may just be less meaningful.
Well, I would be pleased if I woke up tomorrow and saw I got a PM from Lisa Su, telling me I can have all future ES as long as I stop leaking about them

AMD, Apple and Nvidia should currently do well in steel nomad. Since Lunar Lake has battle mage, I am interested to see the differences compared to other architectures.

does terrible in Steel Nomad as compared to any other non-RT test in 3DMark suite, or basically any modern game (for example, in PS5 ports my OC'd 6900xt is probably 20% faster than 3080ti/3090 and is (substantially) faster in many UE5 titles, and it's like 20% under in Steel Nomad). The only game that compares to this is Cyberpunk, and that's a nVidia tech demo through and through

Completely different with RDNA 3 and Ada. Both are different architectures and RDNA 3 performs well in Steel Nomad. I'm not surprised your 6900xt is faster in games than the 3080ti/3090, RDNA2 was on a better node and it was a good architecture plus Ampere was on a worse 8nm Samsung node. Although, not all games are faster on RDNA2 compared to Ampere, Avatar: Frontiers of Pandora which is an AMD sponsored title is better on Ampere in raster.

In fact looking at this leaderboard, the 7900XTX is beating the 4080 Super in Steel nomad. There is no 20% difference with 7900XTX and 4080 Super. RDNA3 is more of a compute heavy architecture than RDNA2 and it shows.

So yeah at least with RDNA3, AMD does well in Steel Nomad.


Even Apple GPUs sucked at compute and it wasn't till the M3 that Apple had a modern compute heavy architecture.
