We are now at a stage where we can say, this really wasn't a tick-tock update was it? As you can see, there are numerous differences in the architecture of the chip and transistor count will back me up on that. See the previous flagship processor had roughly 450 million transistors whereas this Phenom II now accounts for 758 million transistors. And that's pretty significant for a processor. AMD did something bold, they moved a generation ahead of schedule.
Today's processors released:.
- AMD Phenom II X4 920 2.8 GHz (14x200)
- AMD Phenom II X4 940 3.0 GHz (15x200)
So we'll definitely get some better performance out of what is looking to be an impressive processor series. There are more technology advancements and changes though. Let's run through some primary Phenom II advantages.
- Much higher clock frequencies. 3.0 GHz plus a lot of tweaking headroom (we reached 3.8 GHz stable).
- Significant cache changes - 8 MB total for L2 + L3.
- DDR2 and DDR3 compatibility. Though we are testing on a DDR2 platform. Expect 790 chipset based motherboards soon that will allow DDR3 memory. Which again can boost performance from 5 to 10%.
- Clock Multiplier Control on AMD Phenom II X4 940 Black Edition Processors. Processors with Clock Multiplier Control unlock system clock multipliers on motherboards supporting this feature. Tune performance with clock multiplier control on motherboards that support customized processor settings.
Though a couple of processors listed in the following list have gone End Of Life (EOL), let's have a look at the now big the AMD line-up really is and offers:
|Processor||Core Clock||HT Speed||TDP|
|Phenom X3 8250e||1.9 GHz||1.8 GHz||65W|
|Phenom X3 8400 OEM||2.1 GHz||1.8 GHz||95W|
|Phenom X3 8600 OEM||2.3 GHz||1.8 GHz||95W|
|Phenom X3 8450||2.1 GHz||1.8 GHz||95W|
|Phenom X3 8450e||2.1 GHz||1.8 GHz||65W|
|Phenom X3 8650||2.3 GHz||1.8 GHz||95W|
|Phenom X3 8750||2.4 GHz||1.8 GHz||95W|
|Phenom X3 8750 BE||2.4 GHz||1.8 GHz||95W|
|Phenom X4 9100e OEM||1.8 GHz||1.6 GHz||65W|
|Phenom 9500||2.2 GHz||1.8 GHz||95W|
|Phenom X4 9550||2.2 GHz||1.8 GHz||95W|
|Phenom 9600||2.3 GHz||1.8 GHz||95W|
|Phenom 9600 BE||2.3 GHz||1.8 GHz||95W|
|Phenom X4 9650 OEM||2.3 GHz||1.8 GHz||95W|
|Phenom X4 9750 OEM||2.4 GHz||1.8 GHz||95W|
|Phenom X4 9750||2.4 GHz||1.8 GHz||125W|
|Phenom X4 9850 BE||2.5 GHz||2.0 GHz||125W|
|Phenom X4 9950||2.6 GHz||2.0 GHz||140W|
|Phenom II X4 920||2.8 GHz||2.0 GHz||125W|
|Phenom II X4 940||3.0 GHz||2.0 GHz||125W|
So that's a better overview of the assorted Phenom X4/X3 and Phenom II models, showing their clock/HT speeds, TDP, and pricing. Expect a lot of changes in this list this year as AMD will surely move over to 45nm products as fast as they can.
New processors .. does that mean I have to purchase a new motherboard? No, next page please.
We test three AMD processors today, the Phenom II X6 1075T, Phenom II X4 970BE and Athlon II X4 645. They are part of the AMD Q4 processor product line update, arming their processor lineup with more value and higher performing CPUs.
AMD Phenom X4 945 and 955BE processor review|test
Today AMD is releasing two processors in the Phenom II line-up, the Phenom II 955BE and the Phenom II X4 945 processor. Both processors can be considered and positioned in AMDs high-end segment, yet will be priced friendly. Yields are good, clock frequencies go up, performance goes up. And that's nice as the Phenom II series processors offer great performance for the money you have to lay down on the table. AMD Phenom series processors are slowly ripening, and are aging like fine wine (they get even better over time). Guru3D brings you an in-depth performance review and architectural overview on both these processors. Oh yea .. and we'll overclock the living daylights out of it as well.
AMD Phenom II X4 810 and X3 720BE review (AM3)
A test on AMD Phenom II X4 810 and X3 720BE review socket AM3 processors. Socket AM3 Phenom II processors. Processors that are pretty much the same as the Socket AM2+ processors yet now with a DDR3 memory controller. DDR3 memory will allow the overall performance of the platform (your PC) to gain again a little in speed. Over the next few pages we'll tell you all about these new processors, their specifications and of course will check out performance.
AMD Phenom II X4 920 and 940 review test
AMD Phenom II 940 and 920 test. AMD releases the new Phenom II processors. Now manufactured at a much smaller fabrication processes, 45 nanometer, and has different amounts of cache. The result... their processors can now run at 3.0 GHz fairly easy, run cool and still have enough headroom for a nice tweak or two. Pretty significant, pretty interesting.
