- Quad core AMD!
- More than enough power for the average computer user
- Reasonable price
- Shows that the K10 architecture has true potential
- Subpar performance when compared to Intel Quads
- HOT running
- Requires a good board (or else bad things happen!)
- Not as efficient as the Intel Quads
- K10 needs refinement
- Latency Issues
The 7750 brings the Phenom core into the low end of the market and with it allows consumers on a budget to benefit from the more advanced core and features offered by the Phenom architecture.
While the Athlon X2 7700 series CPUs may not twist the nipples of our readers quite so much, for the general public who just want a cheap upgrade with great, well rounded performance, they're a decent heart to a great platform when combined with a 780G board and an ATI Radeon HD 4800 graphics card. What's more, the new Athlon X2 7750 Black Edition and 7550 CPUs appear to offer better price to performance over Intel's competitive offerings and they're certainly worth buying over the older K8 Athlon X2s.
Bottom line: harvesting the Phenom architecture for dual-core ends, AMD's not made many price-related performance gains, but it now has a dual-core architecture that should scale well through 2009, especially as a move to 45nm production is a given.
AMD’s finally introduced the dual-core Phenom they were promising since the launch of the X3, it may not have the Phenom name, but a rose by any other name is still as sweet.
[...], so far it is enough for dual-core AMD processors to retain certain parity in terms of performance with the competitors from Intel – Pentium DC. And although Intel has recently moved them to new 45nm cores, Athlon X2 7750 CPU remains a worthy rival not only to Pentium DC E5200, but also to the newer Pentium DC E5300.
These new CPUs from AMD are good overclockers, good performers and they don't have any real drawbacks unlike their predecessors.
The DDR3 question is easily answered: wait.
By the end of the year we won't be having this debate as DDR2/DDR3 will be at the same price, but if you're building today don't even bother looking at DDR3 unless you're building Core i7. The performance benefits aren't worth it for Phenom II, so while AM3 sounds cool, it's not necessary today. Thankfully AM3 CPUs will work in AM2+ motherboards, so you aren't forced into a relationship with DDR3 if you're not ready.
AMD Beats Intel in 45nm Low Power Server Test.
From a performance standpoint I’d probably still prefer the 2650e over an Atom for a basic web browsing machine. Once you start multitasking (even with multiple browser windows) you start to create an environment that’s better suited for the Atom or the dual-core 3250e.
Power consumption is definitely higher compared to Atom, particularly on the dual-core variant. It’s not enough to make a real difference in your power bill, but it’s enough to keep the chips out of ultra small form factors like the Zotac Mag and definitely out of netbooks.
But overall, if you’re fine with Atom-class performance - you’ll love these two CPUs from AMD. The Athlon X2 3250e brings the best of both worlds, but even the 2650e is a good alternative to the big, er little-A. Especially a single-core Atom.
For those not in the know, Llano is AMD’s first hybrid CPU-GPU with on-die graphics. The graphics core is a derivative of AMD’s DirectX 11 Evergreen lineup (the same lineage as the Radeon HD 5970, 5870, 5850, 5670, 5570, 5450, etc...).
At 32nm each core (minus L2 cache) is only 9.69 mm^2 and is made up of over 35M transistors. Each core is paired with its own 1MB L2 cache, meaning the quad-core processor will have a total of 4MB of L2 on-die. AMD expects Llano to run at above 3GHz, which should be more than possible at 32nm given that we’re already at close to 3GHz with the 45nm Athlon II X4.
AMD’s First Power Gated CPU
Llano uses power gating as well as a Digital APM Module. AMD doesn’t go into much detail on the digital APM module but I’m guessing we’ll see the same sort of turbo-like functionality out of Llano, including graphics turbo.
The talks about graphics processors powering servers have been around for the last three years, but so far only a number of special-purpose supercomputers take advantage of graphics processing units (GPUs) and their extreme amount of cores. But in two years time the situation may become different, claims Advanced Micro Devices and GPUs may find themselves even inside mainstream servers.
