Re: News - AMD Radeon HD 7770 pictured and benchmarked
Well, the VCE not only uses fixed function hardware like Quick Sync but also the compute functionality of the shaders too so it does look a bit more flexible. From what I gather it will have more compression options than with Quick Sync which seems rather limited ATM. Anyway,the proof of the pudding is in the eating so we will need to wait until some reviews are released.

Do you mean lossless encoding?
No....more like lossless transcoding....
Transcode a video using TMPGEnc or handbrake (or a number of other "CPU" solutions)....and then do the same using AVIVO or Expresso using the GPGPU support...
You will see a difference in video quality. The GPGPU solutions are inferior currently.

I guess you mean Trinity? But yeah it would definitely make sense to add it to the IGPs too, and assuming it's the full-featured engine, 'Full Mode' should run at a comparable speed, depending on clock of course.

It's meant to be higher quality than QS, but it's not as simple as just running the transcoding software on a GPU so no, there's no 'full quality GPGPU transcoding' software. Nvidia's original method was pretty poor quality and AMD's didn't give you much choice in CODECs and still wasn't fantastic quality so neither extended to more than a gimmick really. If you look at QS-encoded videos they're actually very good; not software quality but near indistinguishable for the most part. This new engine is meant to be faster and higher quality (faster again in Hybrid Mode - check that link CAT posted) so I doubt the tiny lack of quality will be a problem for most people. Don't forget no widely-used video CODEC is lossless anyway.

Re: News - AMD Radeon HD 7770 pictured and benchmarked
so a return to hardware video work? the one on my R100 was quite good
Re: News - AMD Radeon HD 7770 pictured and benchmarked
Not exactly. Back then, GPUs used dedicated pixel pipelines as opposed to unified shaders, i.e. you had dedicated pixel and vertex shaders, modern cards can use the 'unified' shaders as any to get the best performance out of the card - different games will use different ratios, for instance.
Now we're talking about a hardware video transcode engine which can run the compression algorithm much more quickly than in software in a given power envelope/die size/cost.
Re: News - AMD Radeon HD 7770 pictured and benchmarked
im sure the R100 radeon had a seperate chip for video work
Re: News - AMD Radeon HD 7770 pictured and benchmarked
It was more a predecessor of UVD rather than a transcode engine.

I'd take that with a pinch of salt, given how wrong their leak for the 7970 specs is - just about the only things they got right were the number of shaders and the core code name (and I think the latter was pretty much common knowledge...!).
Re: News - AMD Radeon HD 7770 pictured and benchmarked
Yeah I thought only the high-end cards were GCN but I'd be happy to be proved wrong...
Re: News - AMD Radeon HD 7770 pictured and benchmarked
Well I hope that's a engineering sample cause that's a horrendous waste of space on that PCB. They should make that card as small as possible and stop wasting resources.
Re: News - AMD Radeon HD 7770 pictured and benchmarked
Yeah it almost definitely is.
Re: News - AMD Radeon HD 7770 pictured and benchmarked
Nice to see information on the 7770 and 7970 but still no leak for 7870? Makes me sad.
Re: News - AMD Radeon HD 7770 pictured and benchmarked
It looks like the HD7670 is a rebrand:

I wonder if Trinity is VLIW5 then??
Re: News - AMD Radeon HD 7770 pictured and benchmarked
nv have nothing comparable really - the GT440 costs more and isnt as fast or feature packed :(
Re: News - AMD Radeon HD 7770 pictured and benchmarked
Fermi doesn\'t seem to scale down to the low-end very efficiently or cheaply, it will be interesting to see how GCN compares. But saying that, with increasing IGP power on Trinity and such, it may not be necessary/profitable for AMD to go down that far...

Useless to you maybe, but if you're doing a film to watch on your phone/tablet or upload on Youtube then it's a cracking idea. Arguably more use on the bottom end where the CPUs are lacking, the speed benefits aren't quite so drastic versus an i7, and with an i7 pursuing quality costs you less time.
Quicksync is far better than CUDA or AVIVO, even if it's not as good as un-accelerated encoding.
