Jaguar Hits the Embedded Space
It has long been known that AMD has simply not had a lot of luck going head to head against Intel in the processor market. Some years back they worked on differentiating themselves, and in so doing have been able to stay afloat through hard times. The acquisitions that AMD has made in the past decade are starting to make a difference in the company, especially now that the PC market that they have relied upon for revenue and growth opportunities is suddenly contracting. This of course puts a cramp in AMD’s style, but with better than expected results in their previous quarter, things are not nearly as dim as some would expect.
Q1 was still pretty harsh for AMD, but they maintained their marketshare in both processors and graphics chips. One area that looks to get a boost is that of embedded processors. AMD has offered embedded processors for some time, but with the way the market is heading they look to really ramp up their offerings to fit in a variety of applications and SKUs. The last generation of G-series processors were based upon the Bobcat/Brazos platform. This two chip design (APU and media hub) came in a variety of wattages with good performance from both the CPU and GPU portion. While the setup looked pretty good on paper, it was not widely implemented because of the added complexity of a two chip design plus thermal concerns vs. performance.
AMD looks to address these problems with one of their first, true SOC designs. The latest G-series SOC’s are based upon the brand new Jaguar core from AMD. Jaguar is the successor to the successful Bobcat core which is a low power, dual core processor with integrated DX11/VLIW5 based graphics. Jaguar improves performance vs. Bobcat in CPU operations between 6% to 13% when clocked identically, but because it is manufactured on a smaller process node it is able to do so without using as much power. Jaguar can come in both dual core and quad core packages. The graphics portion is based on the latest GCN architecture.

Today AMD is officially releasing their Brazos 2.0 parts. This is a case of good news/bad news for the company. The good news is that they have an updated product that is based on their very successful Brazos 1.0 platform and that particular part has sold over 30 million units and is included in some 160 designs. The bad news is that AMD did not improve the product dramatically over what we previously had.
While Brazos will not beat these Intel offerings in pure performance, they do match up nicely in terms of price and battery life.
It is well known that AMD cancelled their original Bobcat 2.0 28 nm parts last fall (Krishna and Wichita), and instead worked on improving the fabrication of the current Brazos APUs. Little is known as to why those original 28 nm parts were cancelled, but perhaps the overriding reason is that there simply would not be enough 28 nm production through the first three quarters of 2012 to enable AMD to adequately meet demand on these parts (all the while sacrificing higher margin GPU wafer orders on the 28 nm node). We also must consider that AMD could have been counting on GLOBALFOUNDRIES to have their flavor of 28 nm HKMG process up and running, which of course at this time it is not.
These new Brazos 2.0 chips are still manufactured on TSMC’s 40 nm process, but that particular process is very mature at this time. This has allowed AMD and TSMC to squeeze every last drop of performance and efficiency out of the aging 40 nm node, and in so doing has allowed AMD a bit more headroom when it comes to the Zacate APUs that Brazos 2.0 is based off of. The two new processors are the E2-1800 and the E2-1200.
The E2-1800 is a dual core Bobcat CPU featuring an APU with 80 stream units based on the older HD 5000 series of parts. AMD has renamed the GPU to the HD 7340, though it has little in common with the GCN (Graphics Core Next) based HD 7000 graphics units. AMD increased the core CPU speed from the E-450 by 50 MHz and the GPU portion by 80 MHz. This gives the E2-1800 a core clockspeed of 1.7 GHz and the graphics runs at a brisk 680 MHz. This continues to be an 18 watt TDP part and the die size is the same 75 mm squared.
