Indepth from AnandTech: Intel Medfield / Smartphone info
Intel's Medfield & Atom Z2460 Arrive for Smartphones: It's Finally Here
There's only a single version of Medfield being announced today: the Intel Atom Z2460. The Z2460 features a single Atom core with a 512KB L2 cache, a PowerVR SGX 540 GPU and a dual-channel LPDDR2 memory interface. In a world where talking about four Cortex A9s and PowerVR SGX 544MP2s isn't uncommon, Medfield starts out almost sounding a bit...tame. But then you see its performance !!!!!!!!
[The folks at Intel have outdone themselves with such a strong competitive effort. And the next three generations already being planned out. The future is so bright that all Intel longs will need shades...]
"Now I've got names and numbers to put to it. The HTC Sensation, Motorola Droid 3, iPhone 4S, LG Optimus 2X and Samsung Galaxy S 2 are all featured in the graphs above. Medfield, at least in Intel's reference platform, looks very good.
The actual values are pretty astonishing as well. Sub 20mW idle, sub 750mW during a call on 3G and although not pictured here, Intel's internal data suggests ~1W power consumption while browsing the web compared to ~1.3W on the iPhone 4S and Galaxy S 2. I've done my own measurements on 4S web browsing and came up with a very similar value.
The performance and power data both look great for Medfield. You would think that this data, assuming there's nothing fundamentally wrong, would be enough to convince a handset maker to actually give Intel a shot. You'd be right.
In addition to disclosing Medfield performance data, Intel is also announcing partnerships with both Motorola and Lenovo. The former is a broad, multi-year agreement stating that Motorola plans on creating many devices based on Intel silicon - the first of which will be a smartphone due out before the end of the year. Tablets will follow at some point as well.
Lenovo on the other hand will actually be taking and tweaking Intel's own Medfield reference platform, and releasing it in China in Q2.
All of this is exactly what Intel needed: a start."
The Anandtech analysis does show Medfield delivering impressive performance and probably marks the first real competitive offering Intel has ever had in the mobile space. Compared to years of missteps and failure Intel has had in the cellular market, it's a milestone event. Now they need work even harder to pull in the release dates of the planned enhancements because the competition isn't standing still.
Although Medfield is already posting competitive performance numbers, its current competition is roughly a year old. Within the next two quarters we'll see smartphones and tablets shipping based on Qualcomm's Krait. The next-generation Snapdragon platform should be Cortex A15-like in its performance level
Today we have Medfield, a single core Atom paired with a PowerVR SGX 540 built on Intel's 32nm LP process. Before the end of the year we'll see a dual-core Atom based Medfield with some form of a GPU upgrade. I wouldn't be too surprised to see something like a PowerVR SGX 543MP2 at that point either. In tandem Intel will eventually release an entry level SoC designed to go after the more value market. Finally we'll see an Intel Atom based SoC with integrated Intel baseband from its Infineon acquisition - my guess is that'll happen sometime in 2013.
3.4: 32nm x86 OS-Compliant PC On-Chip With Dual-Core Atom® Processor and RF WiFi Transceiver
ISSCC press materials describe the SoC as a dual-core 1.6GHz Atom® processor with a "custom interconnect fabric, integrated voltage regulators, clock generator with SSC, PMU and a fully integrated RF WiFi transceiver", which the company has implemented in a 32nm high-k/metal-gate CMOS process.
Medfield debuts on Intel's 32nm LP process. The only details we have from Intel are that leakage is 10x lower than the lowest on 45nm. Compared to Moorestown, Medfield boasts 43% lower dynamic power or 37% higher frequency at the same power level.
