The Secret of Ivy Bridge: Power Consumption, Compatibility, Naming...

At the IDF 2011 Information Summit in San Francisco in mid-September, Intel disclosed a lot of details of the underlying architecture of the 22nm Ivy Bridge processor. The "bigpao007" from the domestic hardware forum chiphell has recently exposed some official slides, explaining some of the more "superficial" things, such as it has several core? What is the power consumption level? How is the compatibility? What's your name?

1. Development progress The current version of the Ivy Bridge processor sample is the ES2 (2nd version of the engineering sample), and the QS (Qualification Sample/Qualification Confirmed Sample) which is infinitely close to the retail version will arrive in the mainland as soon as possible this week. Maybe soon. You can see the exposure.

On the motherboard side, the major manufacturers of the 7 series models have been basically completed, just waiting for Intel to announce the market. Manufacturers have even begun preparations for the next generation of Haswell.

2. The number of cores can be completely affirmed. The Ivy Bridge has up to four cores and eight threads, because it is also facing the mainstream market like the current Sandy Bridge, and the top enthusiasts will be handed over to Ivy Bridge-E.

Although this is only the current situation, given that the Ivy Bridge is already in place and Haswell is already in operation, it is impossible to build a six-core system.

3, thermal design power (TDP)

Ivy Bridge's quad-core thermal design consumes a maximum of 77W, which is a significant 19% reduction compared to the current 95W. The new process is not covered. The four cores will also have 65W low power consumption, 45W ultra low power consumption two versions, the brand involves Core i7/i5 two sub-series.

The dual core is up to 55W, which is 15% lower than today's 65W, and there will be a 35W low-power version. The brand's flagship Core i3, Pentium sub-series, but will penetrate the Core i5 in the business sector.

Some Pentium and all Celeron still rely on Sandy Bridge in the short term, and Ivy Bridge may not come to entry level users until 2013.

In addition to the number of cores, thermal design power consumption, brands and specifications are also closely linked: Celeron series has dual core dual-threaded, dual-channel DDR3-1333 memory, 2MB L3 cache, SSE4 instruction set, PCI-E x16 port and other basic specifications Pentium series increased to 3MB L3 cache, and supports DDR3-1600 memory; Core i3 series supports Hyper-Threading (Dual Core Quad Thread), AVX instruction set, Clear Video HD HD video acceleration, Intr3D stereo output, etc.; Core i5 series Welcome It comes with quad-core, Turbo Boost dynamic acceleration technology, 6MB L3 cache, and AES-NI instruction set; the highest-end Core i7 series has eight threads and 8MB full L3 cache.

4, 7 series chipset 7 series chipset models have Z77, Z75, H77 and other desktop versions and Q77, Q75, B75 and other business versions.

In addition to native USB 3.0, the 7 series will also more fully support the SRT, which is currently limited to the Z68's SSD cache acceleration technology, and the version has also been upgraded from 10.5 to 11. I believe the acceleration will be even better.

5, downward compatibility Z68, P67, H67, H61 chipset motherboards have the opportunity (note the word) upgrade support Ivy Bridge processor, and business-level Q67, Q65, B65 on the game, of course, this for the average consumer It also has no effect.

6. The model name Ivy Bridge will still mainly use the Core brand, while the old Pentium and Celeron will continue to exist in the entry level market.

The Core ix number will be upgraded from 2xxx to 3xxx sequence, which is somewhat similar to the Sandy Bridge-E Core i7-3900/3800 series. Letter suffixes still have four types of X, K, S, and T, which represent Extreme Edition, Lock-Free Frequency Multiplication, Performance-optimized Low-Power Version, and Ultra-Low-Power Version.

The Pentium/Celeron number will be increased from three digits to four digits, and will continue to retain the G letter prefix. Pentium will use the Pentium G2xxx sequence, so simply looking at the numbers may be very similar to the current Sandy Bridge and it's easy to get confused. The Celeron side has not yet been made clear. Is it called the Celeron G1xxx?
