We managed to get in one more Podcast before Brian and I leave for MWC 2013 today. With the number of major announcements that happened in the past week, we pretty  much had to find a way to make this happen. On the list for discussion today are the new HTC One, NVIDIA's GeForce GTX Titan, Tegra 4i and of course the Sony PlayStation 4. Enjoy!

Displays by Hybridtechz on Friday, February 22, 2013
Congratulations guys, you are awesome!! Can i suggest to talk in the podcast about smartphone displays? Or even better, write, if possible, a piece about a shootout between smartphone displays? For example it would be great to compare the screen of iphone 5, htc one, asus padfone 2 (IGZO, touch response time 65ms), note2/gs3, droid dna, nexus 4/optimus g...wouldn't it be great? The comparison could coverage visual angles, contrast, birghtness, vibramcy, outdoor visibility and CAN YOU PLEASE ME IF YOU CAN TELL THE DIFFERENCE BETWEEN 720p and 1080p on smartphones? I only trust anandtech so it would be great to hear your opinion...these are only my suggestions, consider them :)

After having followed the rumors for a long time they were pretty much dead on, with the exception of it having 8GB GDDR5 rather than 4 which was a nice surprise. If the Durango rumors are similarly true, it will have not only as much RAM,but much faster RAM than the DDR3 in Durango as well.

The unified pool of memory will be good for passing calculations between CPU and GPU, from what I gather the big limitation to real GPGPU work was passing things between two distinct pools of memory. With one pool both will be able to manipulate the same data without having to pass it back and fourth. GDDR5 may not be ideal for the processor due to its higher latency than DDR3, but that's probably a small detriment in the face of what it will help with.

8 Jaguar cores doesn't sound too bad either, no they don't compete with what we have on PCs, but they'll still likely run circles around the limited Cell and Xenon architectures. And since the OS will have a separate ARM chip running it and there is an dedicated sound processor and video encode/decode hardware, all the Jaguar cores can be truly dedicated to the game.

And the GPU seems good for a console too, not the highest end, but something close to a Radeon 7850 (judging by the 1.84 Tflop number and the GCN architecture) is a huge boost over the cut down Geforce 7800 in the PS3.

I'm excited that console ports for PC will finally move forward, at the very least.

Regarding Intel in consoles, I think there's a reason both they and Nvidia never kept their console partners long. AMD and IBM licence out their chips and allow the console manufacturer to shrink and modify them as needed, Nvidia and Intel maintain tight control. Microsoft got screwed with the Xbox 1 when Nvidia wouldn't shrink it when they wanted. Similar things happened with the PS3. No one partnered with them twice. And now AMD is in all three 8th gen consoles.

A 3 GHz modern Intel architecture in a console would be awesome no doubt, but I'm sure AMD is willing to go much much lower on margin per part considering their situation.

Console makers have to take each change in cost very seriously, a 10 dollar increase from one chip to another spread through tens of millions of consoles is a big hit for any company. I think a modified 8 core jaguar was a fine choice, all considered.

Love the work by watersb on Friday, February 22, 2013
Thanks very much for getting this podcast out before MWC!

I had missed the PS4's unified memory architecture -- GPGPU performance is all about managing the memory access between the GPU and main system, and of course a unified architecture makes things way easier.

Good win for AMD's unified compute strategy.

Regarding OpenCL on nvidia Titan, that problem is just the Windows drivers, right? Linux would get drivers similar to what the Titan supercomputer team has developed?

Pixels by Hybridtechz on Friday, February 22, 2013
I agree wirh ultrapixel stuff...but in an era of ultra hi res displays on mobile defice..4 mpx is enough? I mean a nexus 10 display is 4MP..if i want to zoom in a little to see a face in a photo i would immediately see pixelation? Maybe it would have been better to have a 5-6 MPx sensor, am i wrong?

Am I the only one that can't listen using Opera?
