Intel's Sandy Bridge gets previewed

Written by Slobodan Simic

Looks good for now

We have been hearing and writing about Intel's Sandy Bridge CPUs for quite some time and finally Anandtech.com, or to be precise, Anand Lai Shimpi himself, managed to get his hands on one of these babies and made quite a preview of it. This 32nm CPU with an on-die GPU is something that is eagrly awaited, and it looks like Intel has finally taken the graphics part of its CPU seriously.

This 32nm CPU will feature 64KB of L1 cache (32KB instruction + 32KB data) and 256KB of L2 cache. The L3 cache will be different depending on the SKU so you'll have either 8MB of L3 cache on the Core i7 2600, 6MB on the 2400 and 2500 and 3MB of the 2100. This time around L3 cache matters really much as it is shared by the GPU.

For the first time, Intel has finally taken the graphics part quite seriously as the GPU inside the Sandy Bridge is quite enough to compete with the entry level GPUs. Of course, it is not enough to compete with serious discrete graphics cards but it is nice to know that you get something "for free" once you buy a CPU with on-die GPU. Just for reference, the performance of the GPU on the tested Core i7 2600 was around 10 percent faster than the AMD HD 5450, which is quite good in our book if you consider that we are talking about integrated GPU.

In addition to the CPU and GPU performance improvements, Intel has apparently done a lot to improve the power consumption as well, so Sandry Bridge will be a lot quicker and should draw less power than Lynnfield.

Of course, we are still talking about mainstream dekstop parts, as the high-end parts should arrive sometimes in the second half of 2011. The first preview should get you a general idea about the performance, and also points out that upcoming mobile Sandy Bridge could be quite good.

There will be more information once Intel's IDF kicks off. You can check out the full preview here.

I'd like to see Bulldozer roll over Sandy Bridge.

the whole GPU on CPU shit was thought up by idiots who dislike overclocking.

Maybe they can hire a genius like you to show them how to run their business

Speaking of Bulldozer, the Zambezi desktop part will probably be released in Q4 2011, if all goes well. Over the next year, it will be very hard for AMD to compete with Sandy Bridge with their current lineup (Athlon II and Phenom II. Fusion parts (Ontario and Llano are not at the same performance level as SB.

Since Phemom/Athlon IIs are already behind the current Intel lineup, AMD will fall two generations behind in 2011.

Bulldozer has better be a homerun.

Perhaps the CPU cores aren't but the integrated GPU's certainly are. Llano will wipe the floor with SB graphically, and Ontario will probably give it a run for its money.

amd isnt on the same generation, but its way cheaper, which often is the convincing factor for customers

maybe they could, because they've obviously got idiots like you who come up with stupid idea's like "Lets put a cpu and gpu together so we can waste die real estate with useless transistors and reduce overclockabilit y 40%"

Don't count SB as money maker or big player as it will only hold at most 3% of the market in Q4'11.

Intel managed to piss off a lot of its clients with shady socket "update" practices and I've seen, heard and read a lot of them who own i7's and i5's and don't want to upgrade, holding a bit longer, probably thinking they'd got screwed or that SB is not a sound treat for what Nehalem currently holds.

It'll be the same fight in 2011, well maybe a bit different in the 2nd half, Stars vs Nehalem and later Stars+Llano vs Nehalem. SB will be mostly drool-ware, not something many will be able to / would want to purchase.

Squall_Leonhart was thought up by idiots who disliked birth control.

Remember my friend, it is better to be thought of as an idiot than to use your keyboard and remove all doubt.

According to the Anandtech preview, SB is Intel's next mainstream parts. One will get a lot of performance in a 200$ CPU/GPU.

I have had AMD in my last 2 systems, but if I had to get a new one sometimes in H1 2011, it would be very difficult for me to choose a Phenom II over SB, even for 50$ or 100$ less. This price delta is not substantial in total system cost. The current i5-760 (arguably the sweet spot) is faster than anything AMD has, and SB will be one step above that.

The release of Sandy Bridge will push AMD even more towards the bottom of the market and push prices down on Athlon II and Phenom II. AMD is going to feel that 2011 is a long year. They won't be able to keep pace with quarterly 100 MHz clock upticks on long-in-the-tooth CPUs.
