How will Ivy Bridge compare to Sandy Bridge

[stupidonkey34]

I'm really thinking MBA but if a new chipsize comes out for the first time next year I want to know the comparisons. Being a smaller size how big of a performance boost will come with this? And is it true that they will be out next year?

Less sand, more ivy. That's how.

I'm curious if the Ivy Bridge "3D transistors" will be ready to go at launch and what impact that will have. If it is what they say they are, then I'd think that Ivy Bridge might be a large step forward for computers.

USB 3.0 might join the party.

doubt it, thunderbolt will tho

I honestly wouldn't expect that much of a difference between SB and IB besides maybe a bit less heat, and a little bit more speed, since IB is really just a die-shrink. The next real spec bump will come later.

We are not even 100% sure which sandy bridge CPUs the upcoming MBA will use so I don't know how anyone can draw any conclusions or comparisons between two non-existent products.

you're expecting C2D?

Judging from Apple's late implementation of Sandy Bridge in their current Macbooks and iMac, I think you should consider that it might take at least one additional year after release date for Apple to actually use Ivy Bridge.

Huh? The MBP was the first to use mobile SB CPUs. The wait for MBA was because of waiting for the appropriate low voltage CPUs and now lion as well.

So you know exactly which low voltage SB CPUs apple is going to use?

no, but I'm sure that Apple is going to go with current technology and not an outdated one.

You need to read the posts you quote.

Intel is targeting a 30 percent graphics performance and 20 percent CPU performance boost compared to Sandy Bridge.

Expected Ivy Bridge feature improvements from Sandy Bridge:

• Intel's tri-gate transistor technology
• PCI Express 3.0 support
• Graphics DirectX 11 and OpenCL 1.1 support.

Just don't forget about the microarchitectures and die shrinks to follow: Haswell, Broadwell, Skylake, and Skymont

I'm interested in seeing what the graphics preformence of Ivy Bridge will be like. I keep hearing it will be better than Sandy Bridge, but I'd like to know how much better (probably won't know either until much later this year).

The dilemma of waiting

There will always be a better spec on the horizon, particularly on 'rumour' based websites.

When the next iteration of the MBA comes out, you will need to decide if it meets your needs, if not don't buy one - but it'll be at least 9 months or so to the next one.

The move from Core 2 Duo to Sandy Bridge should roughly double CPU performance* at the same clock speed. The change from Sandy to Ivy is much more incremental (based on what Intel has said thus far).

To give a simple example, take the last two 13" MacBook Pros:

MacBook Pro (13-inch Early 2010)
Intel Core 2 Duo P8600 2.4 GHz (2 cores)
64-bit Geekbench score: 3661

MacBook Pro (13-inch Early 2011)
Intel Core i5-2415M 2.3 GHz (2 cores)
64-bit Geekbench score: 6448

From http://www.primatelabs.ca/geekbench/mac-benchmarks/

Provided Apple make good choices on the rest of the spec, Sandy Bridge should make for a great Air. I wouldn't expect to see major performance improvements until Haswell (due 2013).

*Actual application performance won't double and the performance of games may be lower due to the use of Intel integrated graphics over Nvidia.

Intel confirmed USB 3.0 for ivy.

Intel confirmed that Thunderbolt won't be integrated in 7-series chipsets, but USB 3.0 will.

The successor of Intel HD 3000 (i.e. IB's IGP) will have 16 EUs whereas the Intel HD 3000 has 12 EUs. That is a 33% increase, assuming that everything else stays the same. Since we have no idea about the clock speeds, it's impossible to make any accurate predictions, your guess is as good as mine. I would expect at least 30% increase though.
