Haswell, Cuda, and VP - slightly OT

As you probably know Intel's next architecture, Haswell, is set to release on June 2. It's a new architecture with some significant improvements, AVX2, backside of the execution engine increased from 6 to 8 ports (first change since Conroe), improved branch predictor, improved memory controller, TSX, 2X cache bandwidth, and others. Depending on the coding of Vegas some of these could result in significant performance improvements.

But the big news is that the new GPU, which comes in 4 varieties, GT1, GT2, GT3, and GT3e will support Cuda.

The GT3e supports 40 instruction units (up from 16 in Ivy Bridge) and the "e" means this model has it's own cache. Not integrated into the CPU die but in it's own die on the CPU package.

Anyway I have a feeling this integrated GPU will be the first to actually have enough horsepower to be useful in VP12 and since it will include CUDA hopefully it will be supported.

Should be interesting. This could be the beginning of a very powerful editing platform without a discrete graphics adapter. Imagine how cool it would be to have a quad core Haswell with GT3e graphics in a notebook and have blazing fast Vegas performance?

I'm looking forward to June 2. Plus it's my birthday;)

The I7 4xxx Haswell's are Intel's mainstream CPUs that will replace the 3770K, etc. but by no means will they compare to a 6-core 3930K paired with a GTX 570... You might get 20%-30% better performance over the current 4-core CPUs but that's about it...

According to Moore's Law, about every 1.5-2.0 years CPU performanced should double for the same price... However, without competition from AMD Intel has been happy giving us only about 30% improvement every 2 years... For instance, my 3 year-old 6-core 980X is only about 20%-30% slower than the fastest 6-core Sandy Bridge. Sure it uses more power, but if I want to save power I will turn some lights off.

Intel has the ability to release a non-Xeon 8-core CPU but doing so only means they will compete against themselves... Typically I only upgrade my fastest workstation when the current single CPU solution is 2X as fast as my current CPU. That hasn't happened, so I am sticking with my 980X and eyeing a dual Xeon as my next long-term investment...

Workstation C with $600 USD of upgrades in April, 2021
--$360 11700K @ 5.0ghz
--$200 ASRock W480 Creator (onboard 10G net, TB3, etc.)
Borrowed from my 9900K until prices drop:
--32GB of G.Skill DDR4 3200 ($100 on Black Friday...)
Reused from same Tower Case that housed the Xeon:
--Used VEGA 56 GPU ($200 on eBay before mining craze...)
--Noctua Cooler, 750W PSU, OS SSD, LSI RAID Controller, SATAs, etc.

Performs VERY close to my overclocked 9900K (below), but at stock settings with no tweaking...

--$500 9900K @ 5.0ghz
--$140 Corsair H150i liquid cooling with 360mm radiator (3 fans)
--$200 open box Asus Z390 WS (PLX chip manages 4/5 PCIe slots)
--$160 32GB of G.Skill DDR4 3000 (added another 32GB later...)
--$350 refurbished, but like-new Radeon Vega 64 LQ (liquid cooled)

The big news is the much improved GPU and addition of CUDA. It could be a game changer.

As for the hex core vs. quads. Of course it's hard to make up for more cores with increase IPC. After so much Core development there is only so much instruction level parallelism to be exploited.

That being said, the new instructions could provide huge performance gains if Vegas was coded for them. And another thing going for a more efficient quad is the fact that Vegas doesn't scale with increasing core count all that well. ie you don't get 50% performance improvement (especially with preview where it counts) when you move from quad to hex.
