i5 3475S Release Date & Availability

[XS_Rich]

Anyone know when Intel's planning on releasing this and whether it will be available in retail?

Looking to upgrade my HTPC, and I'd much rather go for the 3475S than the 3570K both on cost and TDP...

the current gen of S chips are not lower wattage on the core they are just set to default one pstate lower but still turbo the same and have a turbo for the pstate it is missing.

So in terms of actual heat load, if it's doing fairly low CPU / high CPU utilization stuff (e.g. madVR at worst), a 3570K will put out as much heat as a 3475S, just doing its work in less time?

the 3570 is clocked higher, if you cap the clock speed in windows so they are the same clock, they will use basically the same power at any given time. with the higher clock speed i am not sure if it will complete a task with less power used but you can always cap the clock speed.

the 3570k is also only $5-15 more here.

also newegg has the S http://www.newegg.com/Product/Produc...82E16819116507 normal - http://www.newegg.com/Product/Produc...82E16819116506

Unfortunately I'm UK based, and I can't see any retailers offering the 3475S yet, other than a few highly suspect 'listings' with no promise of stock.

Given that my workload will be low, I think the difference in listed max TDP (65W vs. 77W) is probably not going to be an issue as you say.

The real question is whether I can get away with a passive Ninja heatsink .... ;D

Recently we delivered a server for low load file management, it is equipped with a Xeon E3-1220L 17TDP. This 1U server with the usual slim copper block can run this at idle easily without the fans running. (Yes, I had to mess around with it, for science!)
Reaching maximum workload the fans don't rally have to work hard and the cooling solution that consists of 40mm fans like most 1U servers don't really cool efficiently.
So we are talking very low loads on the i7-3770k which is clocked to S levels and nerfed elsewhere, then I can easily see you can run this passively with mentioned cooling solution at low loads 10-20% max.
However,
1. 120mm's at absolutely the lowest RPM are pretty much inaudible.
2. If the workload is so small to begin with why not just go for the i3-2120T or similar?

To answer your questions:

1. The case is an Antec Solo, which means the rear case fan (120mm) is basically right up against the CPU socket anyway (well, motherboard dependent I suppose). At the minute it's got an old Ninja (1) on a 65W Athlon X2 and it cools that fine without a fan fitted. I'm going to try the 3570K on a Ninja 3 without a fan fitted and see how I get on. Worst case I can just add a heavily undervolted Noctua to the HS itself.

2. The CPU workload will be fairly low, but I really need/want the HD4000 to do GPU offload for various video decoding jobs (DXVA / QuickSync stuff on MadVR and MPC-HC). Annoyingly the only processors with it are the top of the line i7 (waste of money), i5 3570K (probably what I'll get), i5 3475S (not available yet in UK it seems) and the (IMHO ideal) i3 3225 (which isn't out for ages).
