Intel Medfield: The new CHIP on the block

Nowadays, you guys must be hearing the term 'Medfield' a lot. So, what is Medfield?

If you even have a vague idea of the 'Chips' and 'Microprocessors' market, you would know that Intel is one of the principal market leaders. Laptops and PCs from leading manufacturers like Toshiba, Dell, Lenovo etc. use Intel's chips to power their bodies which has made Intel one of the undisputed leaders in this segment. So, what about the smartphone market then?

Intel, for some reason, hasn't really focused on the smartphone market, which had thrown up a huge opportunity for companies like ARM and Qualcomm to make their mark in this segment. Today, they are one of the undisputed leaders in this market and have even for the last quarter earned huge revenues and also made huge profits by selling smartphone chips. The reason obviously is people's increasing preference towards buying smartphones. ARM and Qualcomm had probably forecasted this then and now are reaping  its rewards.  So, what about Intel?

It seems that Intel have finally realized their mistake and are now focused on gaining a slice of the 'Smartphone Chip' market pie. They are going to be out with their first SoC (System-on-Chip) in this year. The platform for this SoC is named 'Medfield' and the SoC itself has been named 'Penwell'. So, is the 'Penwell SoC' ready to take on established players like Exynos and Tegra? Let's find out.

Intel has demonstrated the power of their new SoC by pitting it against devices like Samsung Galaxy Nexus and have won the appreciation of everybody. The SoC seems to have a 1.6 Ghz single-core Atom Z2460 processor (CPU) and a 400 Mhz Power VR SGX 540 (GPU). In benchmark tests like 'Sunspider Javascript' and 'Browsermark', Intel's SoC has defeated the current leader (TI OMAP 4460 in Galaxy Nexus) by quite a good margin. While the 'Galaxy Nexus' scored 97381 on 'Browsermark', Intel's Penwell SoC scored a better 116425. As you already know, the CPU is entirely responsible for the remarkable performance on these tests and by the demonstration of such performance, it seems that Intel's single-core 1.6 Ghz Atom processor (also called 'Saltwell') is better than TI OMAP's dual-core 1.2 Ghz processor. Guess that the old man did have some wise tricks up his sleeve!!!!

Anyways, what feels like a kind of blip in this amazing SoC is the choice of GPU that Intel has made, a Power VR SGX 540. It's actually surprising why manufacturers like Samsung and Intel are opting to go for this GPU from 'Imagination Technologies' as it has almost been 2 years since it initially debuted in the market. But what actually makes the Power VR SGX 540 in Intel's SoC better than the other Power VR SGX 540s is that the GPU here is clocked at a higher frequency: 400 Mhz. Hopefully, this should make it perform better in Intel's SoC.

So it is pretty clear that if Intel had debuted with this offering for the smartphone market a year ago, it would definitely had a huge advantage and would probably have been rubbing shoulders with the current leaders like ARM and Qualcomm as far as 'Smartphone Chip' market is concerned. Anyways, as the saying goes, 'Better Late than Never'. Initial reviews suggest that Intel's first offering is most definitely not bad and it will only get better when the company comes out with their dual-core offerings. That might actually be the beginning of a new era as far as Intel is concerned.

Stay Tuned..!!

GPU in Smartphones: Mali, Power VR, ULP Ge-Force and Adreno

Well... By now, you guys must have got to know that CPU or Microprocessor or 'The Core' is one of the most important things to know about while finalizing your smartphone purchase. But, CPU only takes care of the normal processing functions for example, rendering Web Pages in a browser and it has a minor say in rendering Images, Video and Graphics, most importantly in Games. The thing that takes care of these functions is the GPU or 'Graphics Processing Unit'. So, if only the CPU is class-leading and the GPU is not, you won't be able to get the best experience from the smartphone you are about to buy. The presence of a very good GPU in today's smartphone devices is the exact reason you are able to play high performance games like 'Riptide GP' and 'Shadowgun' on a device like the smartphone.

So, the role of a GPU is primarily to not only provide hardware acceleration to 3D games and applications  but also to draw the main user interface in mobile operating systems.So, while your switching screens inside your iPhone or Windows Phones and you find the transitions from one screen to another silky smooth, you have to thank the GPU for it.

Right. So who are the market leaders in manufacturing high performance GPUs. Oh!! We have a list here too. Let's dig in.
  1. ARM
    • Ah! Yes!!, one of the market leader in manufacturing mobile CPUs is also the one of the market leader in manufacturing mobile GPUs. It markets it's GPUs under the brand name of 'Mali'. ARM has recently revealed 'Mali T658' GPU for next generation smartphone devices. 
    • The GPU that has brought ARM the most recognition in the recent times is the 'Mali 400 MP'. You have this GPU in the 'Samsung Galaxy S2'. The GPU is one of the reasons the smartphone has become so popular as it is one of the best GPUs to be found on an SoC.
  2. Imagination Technologies
    • You might find this company new, but it definitely is NOT new in the GPU space. Imagination Technologies manufactures world class GPUs and markets them under the brand name of 'Power VR SGX' which has been used in a plethora of smartphones till date.
    • The 'Power VR SGX 543 MP2' is the best GPU currently in the market and you can find it in none other than 'Apple iPad 2'. Now, you can see why Apple's devices get the best ratings not only on the external smooth-running software but also the internal rugged-hardware.
  3. Nvidia
    • Ya!! Nvidia sources the CPU to be used in it's Tegra SoCs from ARM but uses it's own GPU. It markets the GPU under the brand name of 'ULP Ge-Force'. The ULP stands for Ultra Low Power. Most of you would remember that the Ge-Force GPUs manufactured by Nvidia were used in PCs. Well, Nvidia went back to the drawing board and figured out how it could fit the same performance while consuming lower power and generating lesser heat in a device as small as a smartphone and that wondering led to the ULP Ge-Force GPU being born.
    • You can find this GPU in all the 'Tegra 2' SoCs like in the 'LG Optimus 2X'.
  4. Qualcomm
    • I already mentioned in my previous posts that Qualcomm is the company which manufactures the CPUs and the GPUs used in it's SoCs by itself. Qualcomm had actually purchased the GPU business from ATI Radeon but nevertheless, it's got its own GPU business right now. It markets its GPUs under the brand name of 'Adreno'
    • The 'Adreno 220' GPU is the best GPU from the Qualcomm stable in the market right now and it can be found in smartphones like 'HTC Sensation' and 'HTC Sensation XE'.
So, that's it for today. Stay tuned!!!
