Intel z3770 quad core: Intel Atom Z3770 Tablet SoC

IntroductionWindows 8 PerformanceAndroid PerformanceFinal Words

Earlier this year Intel unveiled Silvermont, its first true architectural update to Atom since its introduction in 2008. I won’t rehash Silvermont’s architecture here, but it’s designed to be a true test of Intel’s performance in the ultra mobile space. Leveraging Intel’s first 22nm SoC process and a very low power/efficient microarchitecture, Silvermont aims squarely at the latest Krait cores from Qualcomm and ARM’s Cortex A15.

Today Intel takes the next step forward, introducing the first tablet SoC based on Silvermont: Bay Trail.

Bay Trail takes up to four Silvermont cores, and for the first time in an ultra mobile Intel SoC pairs them with Intel’s own graphics IP. That’s right, rather than using a GPU block from Imagination Technologies, Bay Trail leverages the same GPU architecture as Ivy Bridge.

The first Bay Trail tablets will be shipping by the end of the year, across both Android and Windows 8.1. Intel expects Bay Trail to show up in tablets and 2-in-1s priced below $599, with everything above $599 falling under Haswell’s jurisdiction.

Bay Trail & Branding

Bay Trail, like all Atom platforms before it, will be available in multiple form factors. Unlike the Atoms of yesterday however, the SoC will carry Pentium and Celeron branding when used in notebooks and desktops. Intel didn’t disclose too much about its Silvermont plans in other form factors other than some basic naming:

Basically notebooks ship under the Pentium N3000 & Celeron N2000 series, while desktops will carry Pentium J2000 & Celeron J1000 branding. All Pentium SKUs seem to be quad-core, while Celeron SKUs will be available in both dual and quad-core versions.

Thankfully Intel shied away from introducing the same complexity with its tablet focused Bay Trail parts. All Bay Trail tablet SKUs carry Atom branding. There’s the quad-core Z3700 series and the dual-core Z3600 series.

Although Intel offers both dual and quad-core Bay Trail SKUs, they are both based on the same single physical design. In other words, dual-core Bay Trail parts are just die harvested quad-core parts. Intel isn’t disclosing die size or transistor counts, which is ironic (and disappointing) given that Apple just disclosed both (or at least relative magnitude of one) for its A7 SoC.

Internally, the Bay Trail design is pretty nice. There are either two or four cores enabled, each pair with a shared 1MB L2 cache (2MB total for a quad-core part). Intel is following the unfortunate lead of everyone else in the mobile industry and advertising max turbo frequencies exclusively.  

Thankfully Intel hasn’t yet decided to obfuscate max non-turbo frequencies:

Bay Trail Turbo Speeds
	Z3770	Z3770D	Z3740	Z3740D	Z3680	Z3680D
Max turbo frequency	2.39GHz	2.41GHz	1.86GHz	1.83GHz	2.0GHz	2.0GHz
Max non-turbo Frequency	1. 46GHz	1.5GHz	1.33GHz	1.33GHz	1.33GHz	1.33GHz

In general you’re looking at 1.33GHz — 1.46GHz max non-turbo frequencies, with Bay Trail being able to turbo up to anywhere between 1.83GHz and 2.40GHz depending on SKU.

Although the core architecture is 64-bit in design, there will be no OS support for 64-bit Bay Trail at launch. Windows 8.1 with Connected Standby appears to still be 32-bit only, and obviously Android is 32-bit only at this point as well.

The memory interface is fairly ridiculous by mobile standards. You either get two 64-bit LPDDR3 channels (128-bit total width) or a single 64-bit DDR3L channel. In the case of the former, that’s the same memory bus width as Apple’s A5X/A6X line of SoCs as well as the standard Core i3/i5/i7 parts. Max supported memory frequency is 1066MHz in dual-channel LPDDR3 mode, or 1333MHz in single-channel DDR3L mode. The only benefit to the latter is really cost, as Bay Trail will purportedly show up in some very cheap devices.

The GPU is Intel’s own Gen7 graphics core, a cut down implementation of what we first saw in Ivy Bridge. I suppose it’s premature to expect Merrifield, Bay Trail’s smartphone counterpart, to also use Intel’s own graphics core but it’s clear this is the direction Intel is headed in — and away from licensing IP from Imagination Technologies.

Rather than 16 EUs in the Ivy Bridge GT2 configuration (HD 4000), Bay Trail’s HD Graphics core ships with 4. The 4 EUs are otherwise effectively identical to what we found in Ivy Bridge. The GPU can dynamically scale frequency and share power between itself and the CPU cores. Minimum GPU frequency on Bay Trail is 311MHz and a max GPU frequency of 667MHz (or 688MHz for the DDR3L SKUs).

Intel is quick to point out that Bay Trail’s GPU supports DirectX 11 and OpenGL ES 3. 0. Unfortunately this support list appears limited to Windows. Under Android, it’s unclear whether or not Bay Trail will ship with anything above OpenGL ES 2.0 support. The same goes for GPU accelerated Renderscript. Bay Trail supports up to 2560 x 1440 displays over eDP1.3/DP1.2, or 1080p over HDMI. Panel Self Refresh is also supported.

Video encode and decode blocks also shifted away from Imagination in Bay Trail. Both IP blocks are custom from Intel now. The ISP (Image Signal Processor) is from Silicon Hive (an Intel acquisition).

Speed ​​in games

Performance in games and similar applications, according to our tests.

The performance of 4 cores, if any, and performance per core has the greatest impact on the result, since most games do not fully use more than 4 cores.

The speed of caches and working with RAM is also important.

Speed ​​in office use

Performance in everyday work such as browsers and office programs.

The performance of 1 core has the greatest impact on the result, since most of these applications use only one, ignoring the rest.

Similarly, many professional applications such as various CADs ignore multi-threaded performance.

Speed ​​in heavy applications

Performance in resource-intensive tasks loading a maximum of 8 cores.

The performance of all cores and their number have the greatest impact on the result, since most of these applications willingly use all the cores and increase the speed accordingly.

At the same time, certain periods of work can be demanding on the performance of one or two cores, for example, applying filters in the editor.

Data obtained from tests by users who tested their systems with and without overclocking. Thus, you see the average values ​​corresponding to the processor.

Speed ​​of numerical operations

Different tasks require different CPU strengths. A system with few fast cores and low memory latency will be fine for the vast majority of games, but will be inferior to a system with a lot of slow cores in a rendering scenario.

We believe that a minimum of 4/4 (4 physical cores and 4 threads) processor is suitable for a budget gaming PC. At the same time, some games can load it at 100%, slow down and freeze, and performing any tasks in the background will lead to a drop in FPS.

Ideally, the budget shopper should aim for a minimum of 4/8 and 6/6. A gamer with a big budget can choose between 6/12, 8/8 and 8/16. Processors with 10 and 12 cores can perform well in games with high frequency and fast memory, but are overkill for such tasks. Also, buying for the future is a dubious undertaking, since in a few years many slow cores may not provide sufficient gaming performance.

When choosing a processor to work with, consider how many cores your programs use. For example, photo and video editors can use 1-2 cores when working with filtering, and rendering or converting in the same editors already uses all threads.

Data obtained from tests by users who tested their systems both with overclocking (maximum value in the table) and without (minimum). A typical result is indicated in the middle, the more filled in the color bar, the better the average result among all tested systems.
