LONDON – Qualcomm Inc. has announced it is sampling the first two of its next generation of quad-core Snapdragon system chips and that it already has 50 design-wins for them. The Snapdragon 600 and 800 are powered by quad-core Krait 300 and Krait 400 processors, respectively, enhanced implementations of its currently used ARM-compatible Krait processor.
Some of the key changes in the Snapdragon 200 to 800 family are support for LPDDR3 32-bit memory interfaces to provide memory bandwidth and, in the case of the top of the range Snapdragon 800, support for UltraHD video rendering which is an image of approximately 4k by 2k pixels.
The quad-core Snapdragon 800 uses the Adreno 330 for its GPU and provides a long list of integrated peripherals and capabilities including an LTE modem capable of category 4 150-Mbits per second communications.
The Snapdragon is implemented in a 28-nm high performance mobile (28HPM) manufacturing process from foundry Taiwan Semiconductor Manufacturing Co. Ltd. that has a typical voltage regime of 0.9-volts but can still achieve up to 2.3-GHz clock frequency.
Snapdragon 800 processors will therefore deliver up to 75 percent better performance than the previous generation Snapdragon S4 Pro, Qualcomm claims. The S4 Pro is also implemented in a 28-nm CMOS process.
The Adreno 330 GPU delivers more than twice the performance for compute applications over the current Adreno 320 GPU, Qualcomm said.
Qualcomm has not provided any detail of what has changed between Krait, which powers the S4 Pro, and Krait 300 and Krait 400. The Krait 300 would appear to be in the same low-power 28-nm process as the Krait but can achieve a slightly higher clock frequency of 1.9-GHz, versus about 1.7-GHz. The Krait 400 would appear to be the reworking of the Krait in the 28HPM process for the higher clock frequency of 2.3-GHz.
The Snapdragon 600 delivers up to 40 percent better performance than the Qualcomm Snapdragon S4 Pro processor at lower power, Qualcomm claimed. The Snapdragon 600 sticks with Adreno 320 GPU but provides expanded connectivity. The Snapdragon 600 processor is sampling now and is expected to be available in commercial devices by second quarter 2013. The Snapdragon 800 processors are also sampling and expected to be in commercial devices by the middle of 2013.
“With more than 50 design wins already secured with the first products of the Qualcomm Snapdragon 600 and 800 processors, we are advancing our vision and setting the standard for excellence in mobile computing," said Steve Mollenkopf, president and chief operating officer of Qualcomm, in a statement.
"Qualcomm has not provided any detail of what has changed between Krait, which powers the S4 Pro, and Krait 300 and Krait 400. "
I guess the S4 Pro Krait was modded A9 and the latest Krait is modded A15.
IMO as ARM comes up more optimal CPUs the improvements from 3rd party architectural modifications will wither away.
I have always found it hard to get real details on the Qualcomm devices, but the Snapdragon product line looks to be a great performer. I look forward to the roll-out of the tablets powered by the quad processors running at over 2 Ghz. With this much power and memory options I can't help but wonder what the next generation of handhelds will be like.
running the SoC at 2.3 GHz is well and good but what about the bandwidth between the SoC and DRAM. Even w/ LP DDR 3 at 800 MHz that could be a choke point for flicker free Ultra HD video on the large display
chipmonk, that may be true, but I have to wonder on anything that this chip will be going into, whether UltraHD matters or are you thinking through an external HDMI port? The small displays of what it would go into including tablets would not be able to show all the resolution of UltraHD.
iniewski ... dual or quad would all come down to algorithm and software. For somethings, not much, for others, i.e some image processing where high parallelism is possible, then a lot.
eewiz, already the Qualcomm parts seem to be as fast at lower power than Samsung Exynos, so your comments does seem pretty valid.
