AMD GPU sales tanking

Rroff said:
Something which is annoying on the Ryzen Z1 Extreme - the CPU will sit there at idle barely using any power, the GPU part of the SoC is still guzzling down 4-5 watt despite hardly doing anything.

It's super complex, everything can have an effect power efficiency from the obvious like the size and design of the transistors themselves to the architecture all the way through to the software stack (firmware/drivers).

WikiChip Fuse did an article on the first RDNA (RX 5700) a few year back that may give you a better idea of the sorts of architectural design choices AMD made and how everything from what type of signalling is used on the memory to the width of internal buses can effect power efficiency.

AMD reaffirms Zen5-based "Strix Point" APUs on track for 2H 2024 launch - VideoCardz.com

Zen5 APUs: Strix Point on track to launch this year, Strix Halo reportedly features 40, 32, 24 and 20 CU RDNA3.5 variants AMD is reaffirming that Zen5 Ryzen products will be introduced this year. CEO Dr. Lisa Su claims that the introduction of these next-gen Ryzen “Strix Point” mobile processors...

Strix Halo LP, that's going to be for the next generation handhelds.
 
Isn't the whole consumer market for basically everything tanking? Aside from business to business, stuff made for your average Joe is in the down, likely back to precovid levels it seems.

With gpus still at a high price, it's going back to obscurity unless the mid range is back to decent pricing.
 
New cards are around the corner, so it's expected. In better times when things were in black and white now might be the time there would be deep discounts on current stock, the trouble is even cards AMD have discounted hardly seem like good deals.

Discounted prices are pretty much the prices they should have been at launch.

Oh yeah I totally forgot about that. So is DDR 5 enough for a 40cu Apu?

No, like Hook said it's a bandwidth thing, DDR uses a 64bit bus GDDR uses a 256/512 bit bus.

Theoretically you can increase the size of the bus used on DDR but then you'd need more pins/connections. Currently a 64 bit DDR bus needs 288 pins so if you wanted to use a 256 bit bus you'd need RAM modules with something like +1k pins, that many pins on something like a stick of RAM would come with obvious drawbacks.

Strix Halo apparently uses 256 bit LPDDR5X-8533 with a bandwidth of up 500GB/s and also has a 32MB L4 cache too.

Yeah so is that embedded memory? Lp usually associates with laptops doesn't it? Regardless, that sounds really impressive to me. If it comes to fruition I'd imagine it will sell like hotcakes and kill the low end GPU market. I know I'd buy one.

Great username btw :p

*Off topic....... Is anyone suffering with really bad hay fever? I'm dying right now. Alexa says raw weed or something is in the air along with high pollen counts.
Click to expand...

Not bad hay fever but I've got the slightly choked up feeling today I get when nettle pollen is bad, but I can't see any kind of significant nettle growth - usually I only get it when the verges, etc. are thick with nettles.

I get hay fever every year,but the last week has been brutal. Stinging itchy eyes,and constant nausea. It's making me depressed tbh. Doesn't help that I have a cat which sheds at a rate I've never seen in any animal in my life. Even the slightest pet results in hairs flying everywhere. Sorry for off topic.
 
40 RDNA 3.5 CU's, 500 GB/s memory bandwidth.

By comparison:

RX 7600. 32 RDNA 3 CU's, 288 GB/s memory bandwidth.

It should blow that ^^^^ out of the water...

RX 7700 XT, 54 RDNA 3 CU's, 432 GB/s memory bandwidth.

Probably closer to that ^^^ than the RX 7600, equivalent to an RTX 4060 ti. which i believe in a laptop is an RTX 4070.

Frankly i can't believe how long its taken AMD to get to this point, they could have done this years ago.

When talking about OEM's no one wants AMD's add-in GPU's, but they do want AMD's APU's, they like those, so make them an APU so powerful it doesn't need an add-in GPU even if you're talking about a gaming laptop.

"Yes please, i'll have a few million of them..."
