AMD Phenom II X4 965 BE

Introduction

AMD's release new quad core processor!
 
AMD Phenom IIAs time has gone by, it’s become widely accepted that AMD’s 45nm processors have much to offer to a vast number of consumers. Starting from the runt of the pack, the Sempron 140 2.70GHz single core all the way to the bang per buck monster, the Phenom II X4 955 Black Edition, the CPU manufacturer has aggressively pitched their processors against the entire Intel Celeron, Pentium and Core 2 range, often with lower price tags and/or higher clock-speeds. That's not all because there's also a cracking selection of motherboards from £40 to around £150, most of which sporting the infamous AMD SB710/750 southbridges, which can often unlock the cores of selected CPU's, unlock CPU Multipliers and unlock missing L3 cache. When you factor in that LGA775 will soon be as dead as a dodo and with AMD's plans to retain the same socket for future releases at least into 2011 (according to road maps), Socket AM3 CPU's have arguably become the #1 choice for all users barring the "extreme" performance enthusiasts.
 
So you'd think that after making so much progress after over two years of falling considerably short of Intel's offerings, AMD have some scope to feel a little smug? Sadly, far from it I'm afraid. They may have Intel's line up attended to, right up to the Core 2 Quad Q9650 with it's Phenom II X4 955 3.20GHz Black Edition but only in a matter of weeks, there'll be a new kid on the block who goes by the name of Lynnfield. To be more precise, Lynnfield is Intel's mainstream variant of the existing Nehalem Core i7 but on a new socket, LGA1156. Boasting the same architecture as the number crunching LGA1366 Core i7's, minus Triple Channel Memory, Quickpath Technology, the upcoming lineup is expected to pack a considerable punch within a smaller and less complex package which will inevitably cost the consumer considerably less. It remains to be seen how well these processors will perform and how well they will overclock but if one thing is for sure, now of all days would be the worst time for AMD to sit back with their favourite glass of single malt, watch some television then perhaps go for a nap. After all, if one fail's to prepare then one must prepare to fail and this is exactly what happened when the previous performance champion, the AMD Athlon 64 X2 series received a punch in the face by the well received Core 2 Duo "Conroe" core...And on that bomb shell I wish to present to you the latest addition to the Phenom II family. Meet the AMD Phenom II X4 965 Black Edition.
 
Model Clock Speed L2 Cache L3 Cache Voltage TDP
Phenom II X4 965 Black Edition 3.4GHz 2MB 6MB 0.875 - 1.5v 140w
Phenom II X4 955 Black Edition 3.2GHz 2MB 6MB 0.875 - 1.5v 125w
Phenom II X4 945 3.0GHz 2MB 6MB 0.85 - 1.25V 95w
Phenom II X4 940 Black Edition 3.0GHz 2MB 6MB 0.875 - 1.5v 125w
Phenom II X4 920 2.8GHz 2MB 6MB 0.875 - 1.5v 125w
Phenom II X4 910 2.6GHz 2MB 6MB 0.875 - 1.425v 95w
Phenom II X4 905e 2.5GHz 2MB 6MB 0.825 - 1.25v 65w
Phenom II X4 900e 2.4GHz 2MB 6MB  0.850 - 1.25v 65w
Phenom II X4 810 2.6GHz 2MB 4MB 0.875 - 1.425v 95w
Phenom II X4 805 2.5GHz 2MB 4MB 0.875 - 1.425v 95w
  
So here it is. Another AMD Phenom II based on the Deneb core. 6MB of unified Level 3 cache, 512kB of Level 2 Cache per core and a frisky 2000MHz on the Northbridge Clock. Aside, a 200MHz clockspeed increment, it is no different to the previous Phenom II X4 955 Black Edition. Ah, though it does have a 140W TDP, a 15W increase from the 955BE. From what I gather so far, it's essentially the existing Phenom II with a clockspeed hike along with an increase in reference CPU Voltage to compensate for varying yields on the production line. Going by my previous experiences with overclocking AMD Phenom II processors, I would hope that this is more of a precaution rather than a requirement and that the yields of the Deneb core are improving quite nicely. All should soon be revealed when we get round to overclocking our sample.
 
So here's a couple of questions that need answering. How much of a performance gain can be had from another 200MHz increment? Is this processor worth the £175 price tag? We'll soon find out.

"With a 200MHz speed increase, can AMD's latest Phenom II CPU offer anything more than its predecessors?"

A predictable outcome, but a step in the right direction none-the-less. I keep getting tempted to pick up an AMD CPU just for the sheer hell of it, but other stuff tends to get priorities

Good review

Well thought out set of phrases.

Nice review all though the cpu is not just yet my cup of tee, how ever i will sing a song of Boom Boom Boom Let me way Eh Oh !!!!!! Or was it just a fizz and pop when it blew

nice to see you pushing it to its own demise .. are you going to get a new sample to play with.

Really hoping so as 4.1GHz felt achievable even on the basic Gigabyte board that was used. Even more interesting than the max oc will be what results it gets at 4-4.1ghz

It was very unfortunate that it bit the dust so prematurely. I was surprised because I and many others have pushed AMD Phenom II CPU's past 1.50V on air without any sign of it causing any damage. Overclocked performance would have been something particularly interesting to see as I've found that these processors scale rather well with clock speed increases especially with ramped up northbridge frequencies and DDR3. As I mentioned before, it's also quite well known for the Phenom II to overclock as much as 200MHz less on a 64bit operating system than on a 32bit OS.

It's a little more unfortunate that the E8400/ROG-P45/DDR2 was used as the C2D comparison.

Not that it'd obviously stake any claims to outperform anything, but mentioning a Q9550 - that would have been nice. And a X48 DDR3 sporting mobo too, atleast a P45 DDR3 - particularly when emphasis is made on artificial benchmarks.

I personally see 775 as still a viable option.

Good review and nice to see the AMD benches.

Quick question though.. How can this be mentioned in the conclusion good and bad bit without actually testing said CPU against it?:

"Comfortably outperforms it's comparatively priced rival, the Core 2 Quad Q9550."



Would have been good to see it pitched against a proccy like that though as Rast said.

Based upon experience when handling Phenom II's at 3.2GHz and upwards. It's well known that at these speeds they do indeed outpace the Q9550 but I certainly see where you're coming from as what's been said has little to do with the findings based on the Core 2 Duo and Core i7 used. Perhaps that point is worth ammending

I'm considering buying an AMD machine at the moment, I might go for this chip. I'll just wait a bit longer and see if anything comes along

Planning on building my third PC. I really would like to try an AMD Phenom II instead of the Intel i7. I have only built intel systems. And hope to try my hand at water cooling as well.
