When i upgraded from i5 2500k 4.5Ghz to i7 6700K 4.5Ghz i was surprised how much FPS went UP.
I made complete test with 8 games and here is example:

Skyrim + mods
2500k 4.5ghz 38fps http://abload.de/img/tesv_2015_08_25_13_17tmsse.png
6700k 4.5Ghz 56fps http://abload.de/img/tesv_2015_08_25_19_150asse.png
This translates to 32% increase in fps which is in line with the improvement from Sandy Bridge to Skylake being around 30%. Not really surprising but ultimately the upgrade is still bad decision as the cost of upgrading graphics card would have yielded far better fps increase than spending the money on CPU upgrade.
Edit: Ok i didn't realize you have gtx 970 so in that case don't you think adding another 970 would make much more sense than upgrading from Sandy Bridge i5 to Skylake i7? What was your logic in upgrading your cpu instead of adding another 970 which costs around $300 these days? I really wish to know.Thanks for the benchmarks though its appreciated.
I see some games provide good performance increase while some others show relatively little improvement. So the point being adding another 970 in sli for $300 would make for a much better logical decision than upgrading to i7 for $350.

There are many other things you can do with a PC besides gaming. The upgrade makes total sense to me, even if there was no gain in gaming. The fact that he is seeing improvements is just icing on the cake.
If they can sell these for under $180-200, I'll buy a couple. Hopefully, these ones will have 4GB RAM on them, unlike the Atom Compute Sticks that only have 2GB.

My MeegoPad T02 Compute Sticks thermal-throttle like a MOFO, after running Skype for 10-15 minutes (or less). It seems that they were not built for continuous CPU usage, even though they are only 4-5W TDP. Only seem to be good for "bursty" loads, like web browsing.

You can tell which games are more CPU-dependent and which are more GPU-dependent at the given settings in the data provided by Head1985. Older titles are CPU-limited, while newer ones are GPU-limited.

Agreed. Not sure why some in these forums are so anxious to criticize those who want to upgrade.


Edit: If those results are correct, there is a huge improvement in the minimums for some of the games, btw.

Review sites rarely test mainstream/value parts.
Which is a tiny bit irritating when they're probably a rather better representative of the architecture than the K stuff/their 'forced' very high clock rates etc. Oh well :)

I guess someone will eventually test the 35w stuff at least, and the mobile chips.

I agree.

Whenever they are used. Its always in some other review. So its not like they dont have them.

Has anyone tried overclocking HD Graphics 530 yet?
Jagat got to 1300MHz but I would like to see more results and the performance scaling it provides.


Some Skylake design wins from IFA:

BERLIN – The Asus GX700, showed off at IFA 2015, ushers in a feature never before seen in a gaming laptop: water cooling. The idea behind this innovation? When you combine fast processing and a full 4K display with long gaming sessions, heat often ensues. But water can protect your skin and your machine.
www.laptopmag.com/articles/asus-gx700-water-cooling-hands-on

Props to ASUS for making a stylish notebook with the overclockable Core i7 6820HK inside.

Acer launched both gaming notebooks at the IFA conference in Berlin on Wednesday. Each is packing a number of powerful new technologies inside a chassis that also houses Intel’s new Skylake processors.

Both notebooks will be available in the United States beginning this November, priced at $1,499 for the 15-inch model and $1,599 for the 17-inch Predator 17. In addition to the Core i7-6700HQ chip inside them, the notebooks include an Nvidia GTX 980 graphics chip, up to 32GB of DDR4 memory, and enterprise-class 512GB NVMe PCI Express solid state drives. The Predator 15 offers either a 15.6-inch Full HD (1080p) or 4K (3840x2160) Ultra HD panel, while only the Full HD display is available for the 17-inch model.
www.pcworld.com/article/2979112/software-games/acer-woos-gamers-on-the-go-with-powerful-new-predator-gaming-notebooks.html





The Satellite Radius 12 is a 12.5-inch convertible notebook. Toshiba has provided an option of a wide-gamut UHD 3840x2160 display which gives a smartphone like pixel density of 353 pixels per inch. This is certainly one of the sharpest displays ever offered in a notebook, and the IPS panel supports 100% of the Adobe RGB color space. Most devices struggle to cover all of the smaller sRGB space, so this panel should be great for content creators needing a wider gamut. It is also certified by Technicolor for color fidelity and accuracy. Toshiba offers Chroma Tune software which allows the user to select which color space they want to target for the content they are viewing. The touch screen is protected by Corning Gorilla Glass NBT as well so it should stay looking fantastic for a long time.

Powering this 2.9 lb 0.6-inch thick notebook is of course the latest Intel Skylake processors.

The Lenovo ideapad Y700 Touch is a 15.6-inch gaming laptop powered by Intel’s 6th generation Skylake processors. The laptop features a 1920x1080 display, or you can outfit it with a 3840x2160 offering. The GPU is a NVIDIA GTX 960M which is not unexpected at the starting price of $799. You can get up to 512 GB of SSD or up to 1 TB of HDD or SSHD storage. The battery life is likely going to be not fantastic with just a 60 Wh battery, but gaming laptops are never known for great battery life. Intel outfits the Y700 Touch with a red backlit keyboard, and stereo JBL speakers with a 3 watt subwoofer.

The 2015 Dell XPS 13 and XPS 15 should also be updated to Skylake-U/H soon.

Playing CPU-heavy games, increasing minimum framerates, platform improvements, hyperthreading (i5 -> i7), the various SLI-related headaches, non-gaming uses, etc. Average FPS in graphics-heavy games is far from being the only useful performance metric.

https://en.wikipedia.org/wiki/TWiT.tv

Leo Laporte use to work for ZDTech which was renamed to Tech TV where he did tv and radio shows like The Screensavers, and Call for Help.

In 2005 he started as a side project since he was no longer on TV and just on Radio doing a weekly technology show This Week In Tech (thus the acronym), a few months later it became 2 shows, and then more and more, currently at 27 shows hosted online by various hosts with video and audio podcasts.

4 years after its founding they were making 1.5 million in revenue per year based off doing a few ad reads for a free podcast / free videocast. Last year they made 6 million per year in revenues and this is going to be the 10th year since the 1st show and they believe they are going to break the 7 million mark.

Now this is revenue before paying the staff, bandwidth costs, etc for 27 tv shows. Regardless it is successful. Leo still does a radio program called The Tech Guy and due to syndication with lots of radio stations using him he makes 4 million per year on that.

Latest iPad Pro rumours mention Apple A9X chip, iOS, 64GB base, November launch with limited availability (initially) and premium price tag.

As with the iPad Air and Mini lines, the Pro will be available with built-in LTE capabilities. We’re told that the pricing of the highest-end iPad Pro versions with LTE chips will compare closely to Apple’s latest MacBooks. As the iPad Pro will support a new Apple-designed Bluetooth keyboard, customers may have a tough choice in the $1,000+ price range when looking for either a large-sized iPad or small-sized MacBook.
The iPad Pro will include an A9X chip, which we’ve heard will be a “large” leap over the Air 2’s A8X. It will also have four stereo speakers, but a single Lightning port on the bottom.
http://9to5mac.com/2015/09/07/ipad-pro-specs

Expect a lot of Skylake-Y comparisons given that the next wave of Windows tablets/convertibles (Core M based) should carry similar or even lower price tags. Also the highest-end iPad Pro will cost almost as much as a Macbook (rumour), so people will have to decide between it and an entry-level 1st/2nd generation Macbook 12''.

According to some websites Intel said Core m7-6Y75 is twice as fast as A8X @ CPU tasks. If higher-clocked HD Graphics 530 GFXBench scores are any indication it shouldn't be far from twice as fast graphics performance too. Let's see what A9X brings to the table, this should be interesting.

As I've said before, I believe this is where the first "big battle" will take place, in the Lilliput land :)

It doesn't matter how meaningful the benchmarks are, year over year we're seeing significant jumps in performance from the A chips, and they are doing it with headroom to spare (frequency wise). Meantime Intel keeps peeling away from the power consumption of their strongest cores, dropping watts every year. It's a collision course.

We keep imagining a clash of the titans, Apple's big arm core vs Intel's mighty quad, when the real fight will be fought for the tablet, or to be more precise the device that will enable laptop like productivity with tablet like portability. The winner takes it all.

AnandTech: Updates to Skylake Discrete Graphics Performance: PCIe Optimizations Incoming

AnandTech trying to justify their suspicious Skylake slower than Haswell @ dGPU results:

In our initial review of the two 6th Generation Intel Skylake-K processors launched on August 5th, the i7-6700K and the i5-6600K, our comparative analysis to the previous generations of Intel processors was for the most part, positive. On the whole, clock-for-clock performance was a marginal increase over previous generations but the cumulative end-to-end effort of several generations of upgrades, plus for those that overclock, gave a substantial reason for those in CPU limited workloads to find an upgrade (along with benefits on the chipset and DRAM side as well). However, one element of the equation was puzzling at the time – the performance of games using discrete graphics cards was marginally lower with the new platform compared to older platforms when looking at average frame rates.

During our testing, it is not uncommon to see two platforms that perform similarly to have a reasonable margin of error, often ±1%, due to variations in pre-initialised cache structures, or in the case of games like GRID that rely on a random sequence to provide the end-result numbers. Despite this, we noticed that for Skylake-K we saw consistent drop in our discrete GPU testing, often around the -1% to -3% mark but sometimes as low as -5% or -7% when we compared it to both Intel’s 5th Generation (Broadwell) and 4th Generation (Haswell). Other websites such as The Tech Report also noted these results, placing Broadwell’s numbers at the top of the stack (if only marginal). Some commentary at the time focused on Broadwell’s use of eDRAM in the desktop components which can aid performance while retaining a frequency deficit, although given our analysis of the eDRAM in Broadwell as a victim cache rather than a transparent DRAM cache it seems less likely that this is the case, plus we also now have new information coming post launch about this issue. But if we remove Broadwell as a special case, it was still concerning that the i7-6700K lagged behind the i7-4770K despite being higher in frequency and clock-for-clock performance.

Before it came time to publish our Skylake review, we performed our initial analysis and ended up with our results. Whenever the results are worse than expected, we typically discuss with the manufacturer regarding any anomalies and if they can account for them (or something doesn’t seem to be configured properly). So we passed on our data to Intel as well as ASUS due to our setup at the time, and did not hear anything back for a number of weeks except the odd whisper of ‘we are looking in to it’. Then, in our meeting with Intel at the Intel Developer Forum in mid-August, an Intel processor engineer said that they were still working on it internally, but from their testing it seems that one of the registers controlling an internal frequency was not being set properly during start-up – as in not being set to Intel’s recommended value.

Another couple of weeks later, we were contacted by ASUS who shed a lot more light on the issue. The register in question is called the FCLK (or ‘f-clock’), which controls some of the cross-frequency compensation mechanisms between the ring interconnect of the CPU, the System Agent, and the PEG (PCI Express Graphics). Basically this means it is to do with data from the processor to the GPUs. So when data is handed from one end to another, this element of the processor manages the data buffers to allow that cross boundary migration in a lossless way. This is a ratio frequency setting which is tied directly to the base frequency of the processor (the BCLK, typically 100 MHz), and can be set at 4x, 8x or 10x for 400 MHz, 800 MHz or 1000 MHz respectively.

FCLK is in the top left, between the CPU and the PCIe lanes.

The default value of the FCLK is at 800 MHz for both mobile and desktop Skylake processors, and it is this value that all the motherboard manufacturers have validated their systems on – such as overclocking and margins due to external environmental factors. However, the Intel recommended value for desktops, as dictated in their ‘tuning guide’ for motherboard manufacturers was 1000 MHz, or the 10x ratio setting. The recommended value for laptops is still the 8x ratio setting. [...]
http://www.anandtech.com/show/9607/skylake-discrete-graphics-performance-pcie-optimizations

Next step, admit you should have tested Skylake (and other chips too for a fair comparison) with faster memory so that it doesn't get bottlenecked. :)
