Engineering Sample Of AMD Steamroller Based APU Spotted
Hardware news site WCCF Tech spotted an interesting entry listed in the Bionic research database. The ES (Engineering Sample) chip could be a part of AMD's next-generation APU series featuring the new and improved Steamroller core. While we don't expect performance to increase by leaps and bounds, but Steamroller builds on the Bulldozer architecture and has a target to offer as much as a 30% improvement in performance over the original core.

The ES code 2M186092H4467_23/18/12/05_1304 tells us even more. According to earlier observations (here and here), the four numbers in the middle part tell a bit about clock speeds. If the first one is not 00 (no turbo, see Kabini ES), it indicates a turbo clock of 2.3GHz. The "18? stands for 1.8GHz nominal frequency. I'm not so sure about the "12?. It could stand for 1.2Ghz North Bridge clock. Finally the "05? indicates a 500MHz GPU clock. The right part "1304? is the GPU code, which - thanks to earlier revelations - can be identified as AMD1304.1 = "KV SPECTRE MOBILE 35W (1304)".A 2.3 GHz Turbo core is pretty low, which can be attributed to the early state of the Engineering Sample. Hopefully clock speeds hit further north of just 1.8 GHz CPU and 500 MHz graphics, especially for the 35W part. The next-generation chips will be manufactured on the new bulk 28nm manufacturing process at Global Foundries.

No one bar ibm has much chance of catching Intel on the node front but it is surprising how well they are all still doing with nodes nearly twice the size of intels best.
Ot the gpu has an interesting title 1036 (;) post bin maybe)sorry 1304 could that be an ass kicking shader count??.
Thanks.

Jaguar & Steamroller are on the same node to reduce costs.

As for a 95w part no chance maybe the lower SKU, but AMD is gonna need that higher TDP to be keep competitive. All the 8-core's thus far have been 125w.
What I meant is that Steamroller should catch up in clock for clock performance with Bloomfield, although maybe Clarkdale is going to be a better match. You can do just so much maintaining the same socket for four generations.
In Phenom II era Deneb has ~10% less IPC compared to Wolfdale/Yorkfield. Compared to Nehalem, haves ~35% IPC. Only Llano tied Wolfdale/Yorkfield IPC. Anyway a 20% AVG boost(over Trinty) in STR IPC can make AMD cpus much more competitive on X86 market.
