get your haswell benchmarks here!!!

[deadrats]

ok guys, i've taken the liberty of tracking down links to every haswell review i could find, with an emphasis on video encoding benchmarks:

overall nothing we didn't already know, in general a 4770k is about 10% faster than a 3770k, but you need to really read through the links and analyze the data because there are some juicy little surprises in there:

1) it seems haswell really shines in heavily threaded code (look at the few benchmarks of some apps, the haswell beats some SB-E's).

2) the 128mb eDRAM L4 variant of haswell in some apps can beat a higher clocked haswell sans eDRAM.

3) perhaps most interesting, intel has updated it's quick sync encoder for haswell and added the following capabilities to the hardware accelerated h264 encoder:

Per-MB bit rate control
Trellis quantization
Multi-level hierarchical motion estimation
Multi-reference
Multi-predictor
B-pyramid
Lookahead

this now changes quite a few things and brings the intel h264 encoder feature set more in line with what most popular software h264 encoder offer. one has to assume that main stream apps that license intel's quick sync, like tmpg, will probably be supporting these features in the near future, while i don't plan on getting a haswell, i would assume that the intel software encoder will also support these features and i look forward to testing out the quality of intel's h264 with all the settings maxed out.

OGL and OCL benchmarks look good too. Crazy assortment of parts though. The eDRAM variant is only available in BGA so you won't be able to build your own system around it. The overclockable K parts don't include virtualization features.

yeah, intel has always had an interesting way of segmenting the market, though the eDRAM variant being a BGA only part is understandable. there's been a bunch of backlash from enthusiasts ever since intel announced that all future processors would be BGA only and AMD took the opportunity to make a note how they plan on sticking with FPGA cpu's for ever, intel needs to entice enthusiasts to accept BGA packaging, so they'll make those processors more attractive feature wise so that it becomes a compelling option to the enthusiast community.

i wonder how many years before intel ditches SRAM altogether? i remember reading an interview with an intel engineer on tom's almost 10 years ago where he said that intel planned on eventually using DRAM as cache eventually and i recall him saying that once that became the case there wouldn't be a need for different levels of cache, just one big pool of integrated memory.

imagine what a cpu with say 512mb or 1gb of eDRAM built in would be like.

First review I've seen doesn't look good.

Speed and image quality are down! I don't know if it's a Handbrake issue, user issue, or what.

I've been playing around with Handbrake's QS beta on my Sandy Bridge i5 2500K (no overclock). QS is about 2.3x faster than x264's veryfast preset (and Handbrake using veryfast is about the same speed as the CLI encoder at veryfast) but QS's image quality is significantly below x264 (at the same bitrate).

I've read 4-5 reviews of the Haswell 4770K and they are all underwelming. The slight performance gain comes at the expense of a new motherboard and it seems a new power supply in some cases. It runs extremely hot if you overclock.

seems the haswell 4770k use MORE power than the 3770k. isn't the big selling feature of the haswell supposed to be much lower power consumption? seems the dorky engineers put the voltage regulators inside the chip causing higher heat and more watts being used for not much gain. o/c's lower and it automatically lowers it's own performance when it senses temps are rising unlike the 3770. the 4770k also is missing nice features of the 4770. looks like intel wants to shut down enthusiast builders.

seems the haswell 4770k use MORE power than the 3770k.

The reviews I read only showed that under full load where they are doing even more processing. Power consumption per unit work was still lower.

The bigger power savings is at the low end of CPU usage. Where most computers (laptops and tablets include) spend most of their time.
