Intel's brand new 14nm Tri-Gate transistors aren't afraid of 3 to 5 years old tech.
if Maxwell is "3 to 5 years old tech", what are intel rubbish GPUs ? 20 years old sh*t ? :whiste:
I can't even imagine someone with a brain comparing Nvidia and intel GPUs. Lada Niva vs Porshe Cayenne :biggrin:

I thought it was clear that I was referring to the transistors they're made of. I don't even know if I should even consider a microarchitecture as tech. Even then, I don't think Gen8 will be even close to 20 years old compared to "3 to 5 years old Maxwell."

Does the S805 have hardware H.265 decode? The one thing I want is a goddamn mobile SoC that can do 1080p .mkv playback

Most high end phones already can do 1080p mkv h.264 playback. They can also do 720p hi10p playback (the newest ones can even do 1080p).

Nobody is encoding in h.265 yet though so that's not really an issue.

My Galaxy S4 is barely capable of doing 720p hi10p playback at all and not well. I know the S600 isn't capable of it, I'd be surprised if the S5 was suddenly that much higher performance than the S4 (to do 1080p)

Um, then you need a better video player because MY Galaxy S4 (Snapdragon 600 version no less) plays hi10p at 720p perfectly with softsubs even simply using MX Player (and I know there are other players that have an even better optimized hi10p decoder).

When the GS4 was new the software wasn't optimized and couldn't do 720p hi10p well but that has changed in the past year. 1080p hi10p might still be out of reach but certainly not 720p. H.265 doesn't imply hi10p decoding anyway so it may very well always be software decoding.

Both the 801 and 805 can decode 1080p H.265. I believe the 805 can additionally decode 4k H.265... so basically not something most people care about. Neither one can encode H.265 (so unfortunately no benefit for 4k video recording).

I guess H.265 encoding is critical to recording 4K video? At least with decent frame rates (60+)? You can't write as much data as that quality requires without decent compression, and today's compression schemes would probably do a bad job quality wise.

Are there any Tablets currently with Qualcomm SoCs ???

Not sure if that was a facetious question or not, but yeah there's a metric butt ton load of them.

A few newer / better known ones :

Galaxy Tab 10.1 LTE
LG G Pad 8.3
Lenovo Yoga Tablet 10 HD
Sony Xperia Z2 phone *and* tablet
Nexus 7 2013 model

Im not involved with Tablets as much as i would like so far and that was a genuine question. Thanks for the product list, ill have a more in depth look ;)

I could have sworn that somewhere in that slide it shows that adreno 420 does hardware H.265 decode, and adreno 430 will have encode and decode.

It's in an HTML table, not an embedded slide graphic, in Anand's 805 Snapdragon writeup.

Scroll down to the table titled: Qualcomm's Snapdragon 8xx Lineup

Adreno 420 (Snapdragon 805) and Adreno 418 (Snapdragon 808) have H.265 decode but no encode.

Adreno 430 (Snapdragon 810) has both H.265 decode and encode.

Might want to check out notebookcheck.net for benchmarks and general placement.

That said said, I keep finding that traditional benchmarks are not up to the task of measuring real-world use / performance in the heterogeneous compute space. There are just too many task-specific "add ons" with arm that are not measured.

For example, Moto's X8 has an NLP processor for voice recognition but has a (now older) Qualcomm SnapDragon Pro dual core. It winds up with very good GPU (due to quad Adreno 320) and sub-par CPU benchmark scores that don't tell us much, but it can do things other phones can't without rapidly draining their battery (Google Now will respond to voice even while the phone is on standby due to the customized chip).

The fact that LG G3 might come with a S801 kinda puts in check Qualcomm's statement about first S805 devices arriving in May. I wonder when the first devices will actually come out, perhaps July or August?

Agree, I don't see anything shipping with the 805 in it yet. The 801 seems to be what the newest Android phones are using. I don't see much improvement exc in GPU on these new chips.

Most of the 'new' chips and hot new phones seem to be moving downscale. Moto Q, then Moto E, and a slew of A7 based phones. It's starting to look like the PC landscape, incremental barely noticeable improvements in the top end, but a lot of innovation and variety in the low to midrange segment.

Isn't the 805 for tablets, or did I read that wrong? I thought it didn't have a built-in modem.

It isn't specifically for tablets, but you're correct that it has no built in modem. It looks like it is more efficient than the 800/801 it replaces though.

Biggest move I see on the 805 involves the GPU and GPU/Memory interface. The GPU is now significantly faster than an Apple A7 GPU, but the CPU still seems to lag behind a tad.

Looks like it will not consume any more power than the 801 though, due to a more efficient GPU.

i.e. From AT's preview :

"In order to accommodate the wider memory interface but still make Snapdragon 805 suitable for use in a smartphone as well as a tablet, Qualcomm turned to a different packaging technology. " etc etc.

"Excluding 3DMark, we saw a 20 - 50% increase in GPU performance compared to Snapdragon 801. .."

"The gains on the CPU side are far more subtle. At best we noted a 6% increase in performance compared to a 2.5GHz Snapdragon 801..."
