Discussion Zen 5 Speculation (EPYC Turin and Strix Point/Granite Ridge - Ryzen 9000)

[DisEnchantment]

Speculate at will

 

[Kepler_L2]

Has it been made clear what was the actual cause of this?

Was an optimization to try reducing IF bandwidth bottleneck.

Question about Dawntrail benchmark. What do the blue and green lines signify? I noticed they are quite separated on my 9900X system, and they are joined or closer on other runs Ive seen, including with the 5900X run I did at the bottom?

 

[fastandfurious6]

still no halo leaks?????

is it safe to assume some 10-20% less perf than 9950X or will it be unique because better memory bandwidth etc??

 

[StefanR5R]

Still no EPYC 8005 leaks????? ;-)

Seriously though, are they going to skip this one = double the cadence for "edge" and telco?

(Edit: More properly expressed: half the cadence.)

I think either the existing SKUs are selling too well or not at all.

It can beat 9950X in some benchmarks.

 

[Josh128]

iGPU benchmarks, for sure.

 

[inquiss]

iGPU benchmarks, for sure.

It's gonna have oodles more memory bandwidth...

The Halo series will stay. The future regarding laptop SoCs is big iGPUs and access to lots of VRAM and loads of bandwidth, which will only get better with LPDDR6.

Strix Halo has some issues that will be rectified with Medusa Halo but over all Intel has nothing to combat it next year.

I think you are right but without Nvidia in the name will they sell? Tom's just did an article about the best card at 1080p, 1440p, and 4k and Nvidia is nowhere to be found though. They say don't get an 8GB card, piss on Nvidia's (lack of) value, and say RT isn't worth it most of the time. Maybe people are starting to see the light?

Spoiler: We interrupt our regular programming to bring you a word direct from the Emperor

*Palpatine's voice* Good. Gooddd. Let the hate for Nvidia flow through you. Let it blind you to everything good about Nvidia. For this is the only true path to the Dark Side of cheap gaming

What issues are they, do you think?

Mainly with the iGPU and memory controller

MLID actually "leaked" a supposed Halo Low Power that, to be honest, doesn't make much sense.




If it's an unheard before monolithic chip then those 105W TDP make no sense. There's no way the extra 4 CUs and 16MB IF would push power consumption that far.

If it's a cut-down Halo IOD + 1x Zen5 CCD then it doesn't make sense either, as they're disabling like half the IOD or more.

The RTX 3050 Max-Q as target also seems like such a low bar. Strix Point already competes with that in many games. Why would they make such a chip with such a modest iGPU performance upgrade over Strix Point but with a giant leap in power consumption?

Not supporting the "leak", but it could be a trash bin for chips with one or more of several defects. Defective memory controller, GPU, IF cache, etc. Any one of those could prevent it selling as a top 2 SKU. Everything else gets pushed to that 128 bit bus low spec model, which also works with AM5.

The one thing that might make sense is if it were a desktop part.

THAT'S the news i wanna hear!

halo legion laptop january?? hope not much later

but if even better than 9950X, what's the point of Fire range / 9955hx?

 

[fastandfurious6]

but knowing AMD it's possible we get stuck with some ASUS zephyrusduo $5000 minimum for 6+ months

That's not the segment halo targets.

 

[fastandfurious6]

Thinkpads and professional machines for AI? Thin macbook types won't dissipate ~150watts right

 

[ToTTenTranz]

That's not the segment halo targets.

Which segment, then?

I'd find it hard to believe there's only one segment for Halo.
Just as I think it would be stupid for Asus/Lenovo/Gigabyte/etc. not to come up with a (big and expensive) handheld that claims PS5 performance.

 

[adroc_thurston]

You get thick MacBook types instead. Modern MBPs are pretty chungus alright.

Which segment, then?

various 100W TBP premium™ devices.
It's a CPU + mQ GPU replacement basically.

Good evening folks.

My 9800X3D Dawntrail result. 1.4v+, 5.86Ghz, AIO cooling + liquid Metal.

Indeed,

A single mobile LPDDR6 CAMM2 memory module will max out at ~500 MB/s. That's double the Strix HALO bandwidth or halve the RTX 4090 bandwidth.

Expect beefy iGPU's in the not so far away future.



Trinary signaling can transfer 8x32 bit in 7 cycles over a 24 bit bus. At 14.4 GT/s that amounts to 65.8 GB/s. Eight 24 bit busses add up to ~526 GB/s.
