In the third instalment of their series on the architecture of Nehalem, AnandTech explores the cache size, specifically the itsy-bitsy L2 cache. There is a big trade off in size and latency, much like in any other part and any way to cut latency inside the processor it's self will give some nice returns. They also talk to Intel about the next process, 32nm so head over for bit of prognostication about the near future.

Shanghai is here and it is incredibly power efficient. AnandTech has published their look at this new server chip and it is going to make a lot of people very happy (unless they work for Intel

Tonight at midnight AMDsent out the press release with the formal announcement of their new
45nm 'Shanghai'-based Opteron processors for the server and workstation
markets. There is a lot of great information in this release including
specs of the CPU that show a much better outlook for AMD's processors
than previously expected. Frequencies will be offered as high as 2.7 GHz with TDPs of only 75 watts theoretically indicating that high clock rates should be inbound for both server and desk

You can get a little closer to owning an Intel Core i7 processor; some online retailers are selling the three models as a pre-order, according to CNET. The preorder may ensure that there is stock, but sadly you will still have to wait the six days until the official launch before you can actually lay your hands on it and get it into a system. It still may be a great idea if you want to be the first kid on your block to have one, we really don't know how much stock will be ava

[H]ard|OCP has been spending a lot of time with the new Core i7 processors, testing and retesting as new BIOS, motherboards, RAM and overclocking tweaks have surfaced. One of the biggest hurdles has been cooling these new CPUs, all the previous experience with Core2 no longer applies. There is a video and chart that shows just what to expect with a Core i7 965 and stock cooling ... it's not pretty.

Since the closest you can get to an i7 system is to read a review until Intel finally releases it in the not too distant future, you just can't overclock them yet. That hasn't stopped reviewers from pushing these chips as hard as they can manage. To get an idea what you can expect when you can finally buy one for yourself, drop by bit-tech and see how they made out.

Nehalem is here and it arrived in a huge way, with well over two dozen reviews for you to dig through and have your questions answered. Does the triple channel memory actually improve performance ... yes. Does the new architecture handle multiple cores better than Core2 ... Yes, and in ways you have never seen before. Does it overclock ... oh ya!
What will it cost ... Core i7-965 EE @ 3.20 GHz - $999, Core i7-940 @ 2.93 GHz - $562, Core i7-920 @ 2.66 GHz - $284.
Can you buy them yet ... no.

To kill time waiting for the Corei7 to appear on the market, and likely die in droves as people over-volt them, X-bit Labs is revisiting the current batch of quad core processors. The ageing Q6600 competes against the newer

So, if you make an announcement the night before you make an announcement about making an announcement, doesn't that just beg the press to find out what that same announcement is early? That is what happened to the fine folks at AMD tonight when they sent out a press release about a "significant corporate announcement" tomorrow.

We have been hearing rumors about a potential connection between the CPU voltage of the upcoming Intel Nehalem processor and the system memory for a few weeks but now we have some much more concrete evidence. Images at this site of the ASUS P6T X58 motherboard reveal a sticker on the DIMM slots that says the following:
"...DIMMs with voltage setting over 1.65v may damage the CPU..."
Will BIOS work arounds be the answer for this?

The new flagship CPU from AMD is the AMD Phenom X4 9950 Black Edition, which finally gives AMD a product that can beat the Q6600 at a comparable price. Even better, the overclock that Guru 3D managed on this processor indicates that you can really push this chip, if you stick it in a 790G board. Read on for all the benchmarks of a chip that

It is no secret that AMD has been feverishly working on both their 45 nm designs and the 45 nm process that these products will be produced on. Today we have received word from our friends at C-Net that AMD has apparently overcome most of the hurdles to producing large quantities of these 45 nm parts. Pat Patla, general manager of AMD's server and workstation processors, went on record saying that production of the Shanghai part is now going full speed ahead. While the first chips from this production run have not made it out of the fab, they are expecting to ship the first p

There have been some rumors circulating in recent days that AMD's Bobcat project, a CPU made for the Atom/Nano market, might have been taken behind the wood shed for a little "project culling." According this very short but sweet post at The Inquirer, the deal is done. Another post at EE Times claims that the project is dead as well.

In what will likely be the last series of dual-core processors to come from AMD's desktop team, the Athlon 6500 is based on the Kuma core and runs at 2.3 GHz. It is a 65nm CPU with HT3.0 support, it still uses a built-in DDR2 memory controller, shared 2M L3 cache, Cool''n'Quiet 2.0 and adds SSE4A support courtesy of other K10 processors. Expreview apparently got their hands on one and posted up a review of sorts.

While looking at some pictures of a box, the packaging, the cooler and the CPU inside might not seem that interesting to all of you, it was to me so I thought I would share. This post over at mobile01.com shows the "unboxing" of a Nehalem core LGA1366 processor, its cooler and then compares it to a current LGA775 and AMD Socket 939 processor.

Head to The Guru of 3D for a close look at the performance of Intel's new Atom processor. They have a little ECS motherboard with a Atom 330 Dual Core, running 1.6 GHz, with 2x512KB (1MB) of L2 cache and only drawing 8W of power. It may not have the power to run new games, but there is a lot that it can do; see it for yourself.

We have been hearing about Dunnington for a while, and last week I posted a quick news post about the coming release of the product this week. Well, the news is official and the Intel Xeon 7400 series is the name assigned to these uber-fast and uber-expensive CPUs.

This post over at techPowerUp! actually was posted last week but I just came across it and thought it was worth a post. The original images surfaced from Japanese website PC Watch but the good news is that roadmaps are pretty universal.

TGDaily is reporting that Intel's hexa-core Dunnington CPU (for those of you in the dark, that means 6 cores) for the server/workstation market could be launched as early as next week. This wouldn't be surprising at all considering we first heard about Dunnington in March during the IDF in Shanghai. Don't expect to see these cores in the consumer level products though - your next update will be with Nehalem-based Core i7 in the coming months.
