My Thoughts on FX-8150 vs 2500k vs 2600k - Page 3

post #21 of 62
Long story short, AMD has an entire road map planned out for it's future processor line, all derivatives of the current BD line; "Pile driver"-2012, "Steam roller"-2013 and "Excavator"-2014. Each promises a 10-15% performance increase over the other. The fact in question is that since BD currently only challenges Sandy Bridge, What's AMD going to do when Ivy Bridge finally hits the market? AMD owned the Pentium 4 line with the Athlon FX series back in its heydays. Post Core 2 duo circa 2006-present, AMD adopted the "more cores for less" strategy and it's no different with BD.

This is a sad, sad, day. 10-15% performance increase every year? They'll need 40% per year to make up for this failure. http://www.tomshardware.com/gallery/...-3-1-jpg-.html

As a former socket 939 user, it's disturbingly sad that AMD's latest $269 processor can be beat by an i3-2100 that goes for $124 on Newegg right now...

What AMD is counting on is their new architectural set up. They make use of modules. Each module features two integer cores and a shared floating point core. FP hardware is larger and used less frequently in desktop (and server workloads), so AMD decided to share it between every two cores rather than offer a 1:1 ratio between int/fp cores on Bulldozer. The fetch and decode logic in each module is shared by both integer cores. The role this logic plays is to fetch the next instruction in the thread being executed, decode the x86 instruction into AMD's own internal format, and pass the decoded instruction onto the scheduling hardware for execution. For a single instruction thread, Bulldozer offers more front end bandwidth than its predecessor. Compared to Intel's Core architecture however, AMD is at a disadvantage here. In the high-end offerings where Intel enables Hyper Threading, AMD has zero advantage as Intel can weave in instructions from two threads every clock. It's compared to the non-HT enabled Core CPUs that the advantage isn't so clear.

Honestly I blame it on the motherboards... Who's to say they have the proper firmware installed on launch day.
