Intel 7 series chipset natively support USB 3.0, 8 series released with Haswell processors will naturally continue to be the end of the year, but a document from internal Intel, Intel ran into a "worm".

Intel motherboard manufacturers in this document warning Haswell processor, 8-series chipset system resume from S3 sleep mode, connected devices through the USB 3.0 interface, problems will arise, prior to the visit program and / or data will lose the response, must be re-opened.

For example, if you use Adobe Reader to open a PDF document on the USB 3.0 U disk sleep restored document will display a blank, you must re-open the document, or even restart Adobe Reader.

However, this bug does not cause data loss and other consequences, Intel and its severity column too high, it will not affect the release of Haswell platform upgrade may at a later stage by stepping version to fix.

It is worth mentioning, Intel asked the partners to accept the problem temporarily, before they supply.

Intel spokesman Kristof Sehmke in the accepted inquiry take evasive attitude: "We do not comment on rumors about future products, but I can tell you is, Intel still plans to release the first batch of fourth-generation Core processors, and onto the market will be the end of the year 2013. "

We know the the PS4 from code Liverpool (Liverpool) GPU AMD southern islands R10XX series. Front-end, back-end module, as well as shader core basically has not changed, but added some components for the computing power and efficiency improvement of the common.

Liverpool has calculated loop and pipelines, better control of system resources, and assigned to the GPU load on all applications. These pipes can be synchronous or asynchronous computation.

This figure below shows the the PS4 GPU queue and pipeline:

















PS4 GPU has two loops, 10 pipe 64 queue.



Image (GFX) loop and pipeline

- And R10xx consistent

- Graphics and general-purpose computing

- For games

Loop and pipeline of high-priority image (HP3D)

- Liverpool new

- And GFX pipes, but no general-purpose computing

- Vshell dedicated

Eight general-purpose computing dedicated pipelines

8 - each pipeline queue, a total of 64

- Instead of on the two general R10xx dedicated queue and pipeline

(May be a pipe assigned to Vshell - games and Vshell are seven pipes to the game)

- Queue game series or middleware type to be allocated

- Rendering allows parallel processing and general purpose computing jobs

- Dedicated pipelines of Liverpool's general-purpose computing refresh engine no R10xx of uninterrupted
