Intel Ivy Bridge Dual-Core Put Through Clock-to-Clock Benches Against Sandy Bridge

Taiwanese PC enthusiast Coolaler has a new Ivy Bridge LGA1155 dual-core engineering sample to play with, and wasted no time in putting it through some tests. The sample has two cores, four threads with HyperThreading enabled, clock speed of 1.80 GHz, 256 KB L2 cache per core, and 4 MB shared L3 cache. It is running on an Intel P67 chipset-based motherboard with 8 GB of dual-channel DDR3-1600 MHz memory. At 1.80 GHz, it may not be game for absolute performance figures since it's unlikely that Intel will release a chip with that clock speed unless it has unreal performance:clockspeed gains over Sandy Bridge; but it's good enough for clock-to-clock performance comparisons between Ivy Bridge and Sandy Bridge. A Core i5-2400 was clocked at 1.80 GHz with 18x BClk multiplier, and put through a single-threaded benchmark, and a multithreaded one.

The cache and memory benchmark that measures bandwidth and latency of caches and memory was unable to measure bandwidth, but measured some latencies. The L1 cache at 2.2 nanoseconds (ns), and L2 at 2.9 ns. Next, the Ivy Bridge DC, and the Core i5-2400 (@ 1.80 GHz) testbeds were put through CPUMark 99, where Ivy Bridge DC scored 278 points, and Core i5-2400 clocked at 1.80 GHz scored closely followed at 276 points. Moving on to multithreaded performance, the two were put through Cinebench 11.5 64-bit. The Ivy Bridge DC chip scored 1.81 points; while the Core i5-2400 clocked at 1.80 GHz, scored 2.61 points. Coolaler promises more benches.

Why didn't he just disable two of the 2400s cores?

Well, either way, TPU was mentioned.

So an improvement but nothing WOW realy over SB?

Why is Ivy performing worse than Sandy?

its an early engineering sample so there could be some bugs, the motherboard bios may need some more work as well

edit: besides, the sandy has two more physical cores

Plus he;s comparing a dual-core to a quad-core.

Coolaler is a Chinese language site, you used Japanese as the source language.
Technically, he used auto-detect, which obviously failed. You are right though; if you select Chinese as the source, it translates as, "This on Techpowerup the"

could someone please tell me if IVY BRIDGE is using the breakthrough technology which they revealed a few months back? (the tech where they used 3 dimensional CPU architecture i think)

No, Ivy Bridge is just a shrunk down version of Sandy Bridge. You're talking about the 3D-transistors that got revealed a couple of months back. Don't think it's ready to hit consumer grade products in the near future. In a couple of years Haswell will bring some architectural changes, especially with the GPU-part. Let's hope Intel + graphics unit doesn't equal fail this time.

"Intel demonstrates a 22nm microprocessor – codenamed "Ivy Bridge" – that will be the first high-volume chip to use 3-D Tri-Gate transistors."

Oh didn't know that. Though they would bring that first with Haswell.
lol thanks for that :toast:

Yeah one would think so with the announcement just a couple of months ago. ^^ I think the real difference in performance will be shown with Atom/ULV/LV CPUs, these higher-end will most likely just have an even lower TDP at similar performance levels. But that's just what I think.

What I'm hoping for is that the massive power/heat savings from the die shrink + 3d will give us ridiculously high overclocks. I just worry we might be held back by durability issues.

Are we going to see die size reported as volume instead of area? Also I wonder what the die shots will look like.

they clearly have tri gate transistors sussed as they are also used in intels mic 50 core x86 nights corner(not yet released either) processing card so they must b very confident in the process and architecture, im looking forward to this next war of the cpus, ivy bridge is probably gona be better then this eng sample indicates a lot better.

yes it looks like another 20%-25% where are the days that we got 100 % or at least 50% from
one gen to the other now its moving slower and slower the only winner here is the company
they use less silcon per cpu the client get 20% only .

its to soon to tell but it looks like its legit
