Intel Broadwell Thread

[Arachnotronic]

Really if you want a good CPU you better wait a couple of months for Skylake 4C 8T with GT2. It will be faster with new motherboards, new chipsets with better features etc etc.

If Intel would release a unlocked Broadwell Core i3 GT3e at $150-170 i would consider it to be a good competitor against AMD APUs.

Only very few will buy Broadwell Core i5/7 for the iGPU at that price, and those will be consumers without any price constrains. Only those that dont care about the price and want the fastest NUC based iGPU low power setup.

And you identify here the fundamental problem with tower desktop APUs, both AMD and Intel based. If you want higher-end GPU performance, get a discrete GPU. If you don't care about GPU performance, you probably won't want to pay a premium for Iris Pro.

Broadwell-H and other GPU-heavy SoCs are best suited for mobile devices where power consumption and device size are critical factors. I would guess if you want to keep costs down in an all-in-one, this would be a good use for big iGPU as well.

But for your traditional tower, the value proposition here is unclear. 4+2 Skylake LGA is likely to be far more interesting to the majority of traditional tower desktop users than 4+3e Broadwell.

That said, I believe Intel is basically putting this chip out as a "feeler." If there is actual demand for this kind of SKU, then they will release future versions. If there isn't, then I'm sure they will not. Remember that slide that listed Skylake 4+4e LGA as "conditional"? Bet you that "condition" is how well 5775C/5675C sell.

We need to see the overclocked results. I have a feeling the L4 is helping, but without clock speeds closer to what we would expect, we won't know. In some of the games it seemed to be having a positive effect on minimums, which is really good.

CONFIRMED - H87 Chipsets also support Xeon E3 V4 Broadwell. There should be absolutely NO reason for them to not support the Core i5/i7 variants.

Available Through Simple BIOS Update
GIGABYTE engineers have tested and validated all GIGABYTE C220 series server and workstation motherboards including H87 chipset-based boards to ensure optimal performance for this new Intel Xeon processor E3-1200 V4 product family. Users wanting to take advantage of all the features of this new generations of server and workstation processors have to offer at launch will simply need to download the latest BIOS from GIGABYTE website.

Anyone purchased a 9-Series Motherboard just for Broadwell support? Well, Intel trolled you as AMD did 5 years ago with Socket AM3+ and their 9xx Chipsets for Bulldozer support!

 

[Burpo]

Nobody was trolled. There are features that aren't in 8 -series boards..

Reading the AT preview now. I basically care about gaming (and a tiny bit about video encoding), but it seems that there is actually a tiny bit of performance increase where the last couple of generations have performed identically, like in games with discrete video cards. Given the low clockspeeds of BW, this is promising for Skylake which has higher clockspeeds AND architectural improvements. BW i5 basically edges out the 4690 which is significantly higher clocked.

Should be an easy upgrade for most LGA1150 users then, looks like the talk about only being compatible with expensive H97/Z97 boards is pure crap.

Unlike AMD's APUs this chip has the CPU performance to justify the >$200 price bracket. They are offering the MT CPU performance you'd tipically get from a FX9590 power hog (much better ST performance) coupled with better than Kaveri/Godavari iGPU gaming performance at 65W TDP.

If Broadwell-K overclocks to 4GHz 24/7 without fancy cooling it should outperform most Core i7 4790Ks out there thanks to better IPC + eDRAM, the CPU performance alone could justify the extra $20-30 here if you don't want to buy a new MB and DDR4 memory kit for Skylake-S. Best in class iGPU performance comes as a nice bonus.

For anyone who wants killer x86 CPU performance and don't plan to use dGPUs Broadwell-K is probably a better proposition than Devil's Canyon. Similar CPU performance at stock with lower power consumption and Iris Pro graphics. If you want to go with discrete graphics you still got the CPU performance to push high-end cards and multi-GPUs and if AnandTech tests are any indication the eDRAM might be useful for dGPU gaming.

Gotta say it's funny to see the same people who defended Kaveri compared to other solutions even before the price drops (back when A10 7850K costed $173) suddenly using the 'cheap dGPUs are better' argument now. Oh, the irony.

That is only for Server and Workstation motherboards.

Taipei, Taiwan, June 2nd - GIGABYTE Technology, a leading creator of high performance server hardware, is happy to announce today, in coordination with Intel's official launch, that its entire line-up of C220 / H87 server and workstation motherboards now supports the new Intel Xeon processor E3-1200 V4 product family.

 

[dark zero]

Kaveri could be a formidable opponent... If they aren't throttling so easily.. Only the low tier are smooth...

 

[zir_blazer]

There is absolutely NO technical reason why if a Xeon E3 V4 works in H87, a Core i5/i7 would not. They're the very same Broadwell with different brand name. Otherwise, go around and check how many Desktop Motherboards supports Xeons E3 and Workstation Motherboards regular Core iX. If Gigabyte can do Broadwell on H87, everyone can do it too. Heck, lets not even forget that Xeon E3 V4 was announced to use the C226 platform which is based on the same silicon that all the other 8-Series Chipsets.

 

[crashtech]

But it indicates pin compatibility.

I found my older Post. I made the Broadwell on 8-Series comment back at the end of 2014 due to CPU World news.

Nice surprise, there's a 2+3e Broadwell SKU.

The Intel Core i5-5350H is a fast dual-core processor based on the Broadwell architecture, which has been launched in June 2015. In addition to two CPU cores with Hyper-Threading clocked at 3.0 - 3.5 GHz (2 Cores: 3.5 GHz as well), the chip also integrates an Iris Pro Graphics 6200 GPU with on-package eDRAM and a dual-channel LPDDR3-1866/DDR3L-1600 memory controller. The Core i5 is manufactured in a 14 nm process with FinFET transistors.

I think Intel is slowly paving the way for dual-core GT3e desktop chips. There's a market for them, even if the price comes close to entry-level quad-cores. Can't wait to see how Skylake GT4e performs after today's results.

That is only for Server and Workstation motherboards.

Any particular reason why the same couldn't be done in desktop boards?

But the thing is Broadwell drops into existing motherboards and is only a small premium over the typical Haswell i5/i7 K chips which, when overclocked, it is likely to beat. This chip looks like it competes quite well with haswell. Significantly lower power usage, significantly better igp and media capabilities, and likely significantly better CPU performance than the i7-4790k when overclocked (comparing i7 versions).

If Broadwell overclocks well (4.6 ghz) it will blow past the stock i7-4790k on the order of 10-20%, use significantly less power,and have a halfway decent igp. Is that worth $20?

It looks like the edram is kicking it in some benchmarks. Skylake 4+2 loses the edram and will lose some performance as a result.

Yeah, I could see using those. Probably still whip the A10 even with only two cores.

2 - No remarks regarding if TSX was fixed. First Broadwell Steppings for Core M supposedly were bogus like Haswell, no mentions about TSX in Desktop Broadwell.

Looks like it is enabled.

It doesn't really mean anything. Intel Ark says that Core i7 4790K has TSX, so does my Xeon E3-1245V3, but since they're based on the broken Haswell version, it should not. I want actual confirmation.
Technically, on the Haswells models that had it should come factory-enabled, and a newer BIOS with the microcode patch should disable it. Supposedly on some platforms you would be given the choice to have it enabled anyways for Software development purposes. Regardless, it just adds some confusion, as now you need to search for what models used to have it in case you want to force it on anyways.

Fixed. It just drop-in on the stopgap chipsets launched on 2014, neither H81,B85,Z87,Q87 and H87 will support Broadwell. And the fewer users on H97/Z97 probably have the budget and the knowledge to wait for skylake, considering those users also will find the Iris Pro pretty pointless on their dGPU systems.

Broadwell C to be successful needs to be enabled on the older chipsets if they want wider adoption rates. Even then, the informed buyer will probably wait for skylake.

I have the original 4770 non-K, which I got just for the TSX extension. My BIOS never deactivated it (Gigabyte z87x series). I would hope they have the issue fixed in Broadwell.

@Sweepr - seems like a BGA part. would more interesting if it was a LGA

Take another look at post #2428, especially Gigabyte link. If server versions of H87 are supported, there is little justification not to allow desktop H87/Z87 to use Broadwell at the very least.

According to the following document, die size is 169mm2 (eDRAM die is 80mm2.)

http://www.intel.com/content/www/us...-core-mobile-embedded-thermal-mech-guide.html

Using the processor map below:

I measure the core size to be 6.85 mm2.

In contrast, I got 6.95 mm2 for Core M (when I remeasured today).

 

[cbn]

Regarding my measurements:

I am using the outside edge of the outline as my starting point.

Then I measure the total area for both cores on Core M and divide by two. For the quad core GT3 die, I measure the total area for all four cores and then divide by four.

Already fixed in Core M second stepping, look in the datasheet.
