AMD: Southern Islands (7*** series) Speculation/ Rumour Thread

[Gipsel]

Unless the crossbar between CU's and L2 was built to service non conflicting transfers in parallel.

A crossbar does that by definition. Otherwise it would be a bus.

Good to know.

The roadmap showed GPU+mem interposer at the end of 2013. We can expect they'll release at least 2-3 product generations (or refreshes) in the meantime.

Which roadmap?

 

[no-X]

Amkor's

 

[MfA]

Interposers will do very very little for performance without a new wide-IO memory standard, they can allow lower power or slightly higher clock speeds with existing memory standards ... but it's not going to be a big leap.

Their first use will probably in high margin mobile phones ... not graphics cards, unless AMD or NVIDIA decides to push their own custom RAM.

Screw WinZIP, what about WinRAR?

Screw WinRAR and WinZIP. 7-zip kills them both.

Google Translate:

Sometimes you know something for a while and you can not say. Thanks to a leak of semi-accurate, we can finally say that the Radeon HD 7900 -, 7800 - and 7700-series, all three use the all-new Next-Core Graphics architecture!

The HD 7600 -, 7500 -, 7400 - and 7300-series are direct rebrand of the previous generation. The HD 7400 video cards are exact copies of the HD 6400 cards, the HD 7300 GPUs are the same as the HD 6300 graphics cards and the HD 7600 - and HD 7500-series remain unchanged and are based on the Turkish-GPU, we already encountered in the HD 6000-series. Everything from the HD 7600 series is seen down, based on the old architecture (VLIW5) and therefore only available to OEMs.

The release of the HD 7970 and HD 7950 follows on January 9, on 22 December the reviews of the HD 7970 already

Dunno, I've been happy with 64bit WinRAR, more so than with 7-zip. Could be partly due habit though, as I used RAR with DOS too, when it replaced ARJ as the preferred tool for compression

nice to see a slide from different source not obr-donanımhaber

Not to derail so please forgive...7z/7-zip supports more formats and is free, hence, better

My guess:
Pitcairn:20CU,256bit,250mm2,6950~6970 performance
Cape Verde:10CU,128bit,130mm2,6770~6850 perfomance

 

[Kaotik]

My guess:
Pircorn:20CU,256bit,250mm2,6950~6970 performance
Cape Verde:10CU,128bit,130mm2,6770~6850 perfomance

I'd expect Cape Verde (7700) to be at least on 6870-5870 level, Pitcairn (7800) just around 6970 (xx70 above, xx50 below)

 

[Mindfury]

I'd expect Cape Verde (7700) to be at least on 6870-5870 level

If so,they will need a wider bus than 128bit,I think that won't happen on a replacement for Juniper.

Well the performance "has to" go up, HD6-series was exception obviously (due obvious reasons, too), but other than that HD4770 was around or even over the performance of HD3800's, HD5770 was around or even over HD4800's, so it would be logical that HD7700 would be around 5800/6800 performance

 

[Alexko]

My guess:
Pitcairn:20CU,256bit,250mm2,6950~6970 performance
Cape Verde:10CU,128bit,130mm2,6770~6850 perfomance

I think CU count has to be a multiple of 4, so 10CU isn't possible—unless GCN is a bit more flexible than we were led to believe.

 

[Man from Atlantis]

It would be nice Barts replacements Cape Verde 1.5GB vram(an upgrade purpose for barts owners) 192bit 5.5/5.0Ghz chips.. and Pitcairn 256bit 2GB and Tahitis 3GB with 384bit.. and Turks and Caicos 128/64bit rebrands.. nice scale me thinks

Power Tune parts:
the introduction of a more a more granular power control, based entirely on digital technology (Status Register?), independent of the driver and configuration files.
In the "black" state or PC into idle mode, GPU core state into the 0 watts, the fan will turn off, CFX configuration, when this technology is very attractive 7970 TDP is about 210 watts, 7950 is ... to be determined.
7970 frequency is 925 MHz (2048 Core/32 CU), the memory is 384-bit@5.5 GT / s..
7950 core frequency specifications to be determined, but the core is 1792 to determine the number of / 28 CU, memory bus is still 384-bit, but the rate of reduction for the 5GT / s (AMD's own not fully determined) level.

HD3D parts:
7900 to achieve the single-GPU multi-screen, multi-track orientation of the output stream
will be launched in February next year, a custom resolution (yeah!), pre-configuration management, the task of cross-screen technology

Video part:
UVD 3.0 generation still remains the same.
Focus here, is called VCE 7900 with the hardware video stream encoder and more, to achieve more than 1080p60 h.264 video encoding hardware to support full hardware encoding and fixed-function GPU shader supporting hybrid coding mode.
Compressed 4:2:0 color space encoding
quality to choose from a variety of compression
previously mentioned QSAD to achieve stability of steady video screen technology video acceleration, the new steady video 2.0 also supports interlaced video, and provide contrast mode about new features.

i hope custom resolution is something about downsampling
