Sandy Bridge Core i3 i5 & i7

[Finny76]

How come there are so many variants of the Sandy Bridge Core i3 and i5 BUT only 3 versions of the Core i7?

Will INTEL release any more Core i7 SB processors soon?

Will INTEL release any more Core i7 SB processors soon?

Although there is a >= 2600K on the leaked road map I do not believe we will see any more 1155 SB processors with SB-E coming up an a few months and a non competitive AMD.


I believe Intel wants to keep a clear separation in performance between the lga1155 and lga2011 processors. I believe this is one reason why a 95W part is the fastest lga1155 chip. lga2011 will have 95W to 150W parts.

 

[IntelEnthusiast]

A simple decoder for 2nd generation desktop Intel® Core™ processors:

Normal processors and S and T processors all come with TXT (Trusted Execution Technology), VT-d (Virtualization with Directed I/O) and the Intel HD 2000 Graphics.

S=power saving 65w (in most cases), also might see a drop in clock speed to reach the lower TDP.

T=our best power saving desktop CPUs. They are running at 35w or 45w TDP. Lower clock speed but biggest power savings processors. These processors are also coming with also come with a low profile HSF (heatsink/fan) for use in HTPC and Mini-ITX builds

K=unlocked multiplier (for overclocking), also coming with the Intel HD 3000 Graphics. These processors don’t come with TXT and VT-d support. Also the processors with the model # ending with a “5” (like the Intel Core i3-2105) come with the Intel HD 3000 Graphics and don’t have the TXT and VT-d support.

Intel Core i3: (These processors are designed for entry level users)
-Dual Core processors with hyper-threading

Intel Core i5: (These processors are designed for main stream users)
-Quad Core processors
-Turbo mode will automatically clock the speed of the processor up based on how many cores are being used and the temperature of the processor.

Intel Core i7: (These processors are designed with the power user in mind)
-Quad Core processors with hyper-threading (4 core/ 8 threads)
-Turbo mode
This should give you a good idea on the wide range of different processors we offer and the features on each of them.

This is probably the real reason. If AMD has something competitive with BD, then you might see Intel release a new chip but for now, there really isn't any reason for them to ship anything faster.

Yes I completely agree with this: why glut the market with high-end 1155 parts when idiots will pay double the money to have four worthless memory channels?

Also, the reason you have so many i3 and i5 parts is because you have a wide range of dual and quad-core performance to cover. The i7 is a high-end premium part, and since it makes no sense to have "slower" i7 parts, you only get one at the top

How come there are so many variants of the Sandy Bridge Core i3 / i5 but only 2 versions of the Core i7?

Intel SB Core i7: 2600,2600K

They don't need to. The not so large price premium of the i7K over the i5 family provides users with a stepping stone into the enthusiast realm by means of the capability to oc by a huge margin utilizing the oem hsf or an inexpensive 3P unit. It would be pointless to release any i7s with higher factory clock rates since they would likely top out in oc'ing what the 2600K will top out at anyway, but costing the end-user more initial out of pocket cost.

There's more but they are hidden under xeon brand name

Agreed, I see this as the biggest reason there aren't more. There's no point unless you offer one with more cores or some such.

Indeed. And there likely won't be any core increases on the 1155 platform, as the 6 and 8 (possibly more) core units will likely be reserved for the S2011 platform only, thus defining a new true-enthusiast level for intel.

Intel SB Core i3: 2100,2100T, 2105,2120T,2120,2125,2130
Intel SB Core i5: 2300,2310,2320,2400,2400S,2500,2405S,2500K
Intel SB Core i7: 2600,2600K, 3820, 3930K, 3960X

Fixed.
The current lineup of Xeons are:
Equivalent to i5 2500:
E3-1220 3.2GHz, No on die GPU.
E3-1225 3.1GHz, on die GPU.
Equivalent to i7 2600:
E3-1230 3.2GHz, No on die GPU.
E3-1235 3.2GHz, on die GPU.
E3-1240 3.3GHz, No on die GPU.
E3-1245 3.3GHz, on die GPU.
E3-1270 3.4GHz, No on die GPU.
E3-1275 3.4GHz, on die GPU.
E3-1280 3.5GHz, No on die GPU.
E3-1290 3.6GHz, No on die GPU.

The ones in green are Socket 1155. The ones in Orange are Socket 2011.

 

[mrbigshot]

+ e3-1290 3.6 8mb 4core, no gpu socket 1155

theres also these 2011 xeons, any of them could become i7s at a moments notice, even the 8 cores

Exactly my thinking, so I'm holding onto my 2600k until 2011 comes out and I can move to that.

not totally true. Intel likes to play with product names

below, i5-2390T with 2 cores, 4 threads
http://ark.intel.com/products/53448/Intel-Core-i5-2390T-Processor-(3M-Cache-2_70-GHz)

(even more disparity b/w i3, i5, i7 for the mobile line)

 

[bwang]

Intel's naming conventions are horribly annoying...between the slowest "i7" (620UE) and the fastest (990X), there is a tenfold performance difference on multithreaded tasks =(

 

[tunesintheattic]

The way I see it it's sort of like car makers. There's a lot of low end model's out there but when you get to the high end models your selection is limited because they have it all.

Even in desktop chips this isn't entirely accurate. There are many dual core i5 chips (mostly clarkdale but also one sandy bridge).

Once you look at the laptop chips things get a WHOLE lot messier. You see a nice looking machine that is marketed as having an i7 but when you look closer you discover it has one of the crappy "ultra mobile" chips.
