Zhentar posted:That sounds exactly like an enterprise feature to me. Consumer applications are extremely slow to uptake new processor features, because it generally isn't easy to support the new feature without breaking compatibility with old processor revisions. That's the thing, though, only libraries need to be updated, and those libraries will have automatic backwards compatibility. GCC 4.8, the latest Visual Studio 2012 update, and Intel's own compiler all have that TSX support and development done. The only thing an app developer needs to do is link to a sufficiently new version of the library.

Ughh, I don't want to wait for Broadwell to build a new PC so I'll probably just pick up a Haswell later this year. Broadwell will use the same socket as Haswell right?

Those virtualization improvements are giving me a nerd boner. Next thing they'll add is GPU virtualization extensions with Broadwell beating nVidia to the punch and I'd have a small nerdgasm.

Lower-end models might not be available in socketed configurations at all, it seems. Our source did, however, reaffirm Intel's position that socketed CPUs aren't being dropped completely.

Either way, there is no solid information out there and Intel went out of their way to quash the BGA thing once already. So I'd think we should probably wait and see.

Will it be worth upgrading to Haswell from a i5-2500K chip for gaming? I would only have to upgrade the CPU and motherboard and keep everything else right?

I doubt it. Depends on the game, I figure, whether the game is CPU heavy or not. I'm personally only upgrading from my i7-2600 due to the virtualization stuff. I'd figure the ~15% plus in IPC, improved hyperthreading and faster VM stuff will be noticeable in my scenario.

I think for most games, even a Nehalem quad will be more than enough, especially if overclocked. And for general purpose work/Internet machines, that + 8GB of RAM is plenty. Really the big improvements as we all know will be mobile; CPU performance boost with an iGPU that may preclude the need for a discrete chip And improved battery life? Yes please. e: One big thing I forgot though, is the upcoming HEVC (successor to H.264 / AVC). That coupled with 4K resolutions could be rough for older hardware that either don't have GPUs/similar hardware to decode assist, or can't be upgraded to have it (i.e. older laptops). Current-gen tablets / portables are of course completely hosed unless their ASICs secretly have the flexibility or IP to handle it. movax fucked around with this message at 00:52 on Mar 24, 2013 |

Has there been any more news about the integrated wifi chip on the cpu? I'm guessing from the lack of info it won't be coming out this year. Seems it'd be a major boost to mobile battery life.

Hevc content basically doesn't exist so it'll be a few years before we see it being used even internally. Avc took a while to take off after it was ratified so by the time it becomes relevant people will have the hardware

Certainly on the haswell front. Could be wrong, though

I'm pretty certain a 2500k with a healthy overclock is not going to be out of date any time soon. However, once the new consoles arrive, we can expect things to move in terms of requirements as a knock on effect.

Just want to add, I don't really care about 4K resolution until I can buy a 4K monitor for my workstation. The way next gen consoles are speced, we're probably not going to be gaming at 4K until the next-next generation, i.e. whatever is after the PS4/XBox 720. Considering Sony & Microsoft are trying to get 10 years out of the console, that is not going to be anytime soon (albeit I would not put money on the PS4/720 actually hitting the 10 year mark).

4K on consoles would either be interpolated, like 1080p on current ones, or they'll be trading polygons for resolution. At 4K resolution, games can however drop all antialiasing, making up a little performance there.

Rumors abound on the GPU configurations for mobile Haswell. As review:
GT3e will be HD 5200, and will be implemented in high-performance, high-TDP quad-core chips with the suffix -HQ. So far, two such SKUs are revealed, the i7-4850HQ (2.3-3.5 GHz, 3.3 GHz max 4C turbo) and the i7-4950HQ (2.4-3.6 GHz, 3.4 GHz max 4C turbo), both 47W TDP parts. The max IGP clock will be 1300 MHz on both parts. The other SKUs will apparently be binned based on clocks. GT3 will be HD 5000 and HD 5100 in Ultrabook SKUs only. GT2 will be HD 4200 and HD 4400 in Ultrabook SKUs and HD 4600 in higher-TDP, higher-clock SKUs.  Different names based on clocks/TDP isn't a terrible thing. Though HD 4000 is hardware-identical on ULV i7s and high-TDP performance quad-core i7s, the real-world performance is very different due to TDP limits and clock throttling. The new names will be a bit clearer to consumers who aren't turbogeeks.

They'll also probably win a Nobel prize for physics, what with figuring out room-temperature superconductors to cool a 47W chip in a form factor that normally struggles with a third of that.
