Intel Tiger Lake: Release Date, Specs, Benchmarks, and All We Know

Attachment 43021

Intel has finally pulled the veil off of the final specs of its 11th-Generation Tiger Lake processors after slowly trickling out details of the new chips for an entire year. The TIger Lake chips look to slow AMD's advance with its impressive 7nm Ryzen 4000-series "Renoir" chips that have steadily gained traction over the last several months, but Intel is finally moving on to its 10nm SuperFin process that brings higher clock speeds and a big 20% boost to performance. Intel has also finally shared benchmarks that give us at least some idea of how its chips stack up against the Ryzen competition – Intel claims its quad-core models are faster than AMD's eight-core Renoir chips, and that its integrated graphics have finally taken the lead.

Intel's Tiger Lake brings a dizzying array of improvements over the company's previous-gen Ice Lake with higher clock speeds, a doubling of graphics performance, the first PCIe 4.0 support for laptops, and support for LPDDR4x memory serving as the headline advances. After Intel shared the technical details of its architecture, the new 10nm SuperFin process, and even more low-level details, we now have all the info condensed down into this article. Let's start with the chips.

Intel 11th-Gen Core Tiger Lake UP3 Specifications

Attachment 43022

Intel announced a total of nine new chips. We have the nitty-gritty specs below, but first we'll break down the meaning behind the confusing mish-mash of product identifiers.

Intel's Tiger Lake comes with the Willow Cove processing cores and Xe LP graphics graphics on one larger 10nm SuperFin die, and a separate smaller 14nm PCH (platform controller hub) chipset that handles extra I/O and connectivity duties.

Intel has two basic packages: The larger package on the left is for the high-performance UP3 models (formerly U-Series) that operate within a 12 to 28W TDP, and the UP4 package (formerly Y-Series) on the right for devices that operate at 7 to 15W. These packages are then integrated onto incredibly small motherboards (second picture in the album) that find their way into the new Tiger Lake laptops and thin-and-lights.

The Tiger Lake chips span the Core i7, i5 and i3 families and come with varying levels of graphics performance. Intel splits its Xe LP graphics up into G7 and G4 families. Tiger Lake models with "G7" at the end of the product name come with either 96 or 80 execution units (EUs), with the full-fledged 90 EU models coming with Intel Iris Xe branding. Chips with "G4" at the end of the product name come with 48 EUs. Naturally, the Iris Xe models with more EUs offer the high end of performance, which we'll see in the benchmarks shortly.

You'll notice that Intel has discarded its practice of listing a single TDP value. Instead the company now defines a full dynamic range of performance that spans 12 to 28W with the UP3 models. This allows laptop makers to tailor the chips for the thermal capabilities of their products, with high-end models having sufficient cooling to enable full performance, while lower-end models with less-capable cooling can be tuned to a lower TDP setting. The TDP can even change while in use based upon device temperature, power delivery, and orientation. Intel doesn't require laptop makers to list their TDP ratings, though, so you'll have to turn to third-party reviews for the full skinny on performance.

The flagship Core i7-1185G7 leads the UP3 lineup. This chip boosts to 4.8 GHz and has a 3.0 GHz base frequency, both of which are a big increase of 700 MHz over the previous-gen model. Intel has also made a big step forward with a 4.2 GHz all-core boost clock that will help chew through demanding productivity apps. To put that in perspective - the maximum single-core boost from AMD's fastest Ryzen 4000 processor weighs in at 4.2 GHz. Intel can pull that off on all cores at once, which helps explain some of its performance advantages we'll see in the benchmarks below.

The 1185G7 also comes with the Xe LP graphics engine with the full complement of 96 EUs, so Intel brands it as Iris Xe. The graphics unit runs at 1.35GHz, an increase of 250 MHz over the previous-gen graphics on the Core i7-1068NG7. The chip comes armed with 12MB of L3 cache and supports LPDDR4X-4266.

The Core i3-1115G4 slots in as the low-end model of this line up. This dual-core quad-thread chip comes with a 3.0 GHz base, 4.1 GHz boost, and impressive 4.1 GHz maximum all-core frequency. The chip's Xe LP graphics engine comes with 48 EUs and boosts to 1.25 GHz, which is pretty agile for a low-end chip. However, these chips step back from LPDDR4x-4266 support to LPDDR4x-3733, which will hamper performance in some tasks. Notably, the Core i5 and i3 models come with 8MB and 6MB of L3 cache, respectively, which is less than the full 12MB found on the Core i7 models.

The UP4 models slot into a 7 to 15W performance range for premium ultra-thin devices, including fanless models. Here we have Tiger Lake Core i7, Core i5, and Core i3 models, just like with the UP3 family, but with pared back frequencies to enable the lower level of operation.

The Core i7-1160G7 comes with four cores and eight threads paired with Iris Xe graphics that operate at a 1.1GHz boost clock, while the low-end dual-core Core i3-1110G4 comes with a 48 EUs that boost up to 1.1 GHz. All of the UP4 models support LPDDR4x-4266.

We'll cover the details of the Xe LP graphics engine below, but for now, let's see the new Iris Xe integrated graphics in action. Intel shared plenty of its own results during the launch, but as with all vendor-provided benchmarks, take these with a grain of salt.

Intel claims it's Xe graphics outperforms AMD's Ryzen 7 4800U by up to 1.8X in a range of titles, and that it can even tackle Nvidia's discrete MX350 in 1080p gaming. That could eliminate the need for a discrete graphics card in many of the Tiger Lake laptops, but we're sure Nvidia and AMD will whip up new models to up the ante.

Compared to the previous-gen Core i7-1065G&, Intel says the Core i7-1185G7 offers a neat doubling of performance. Of course, these performance figures outline the highest-performance configuration, so performance with fewer EUs and/or tighter thermal constraints (like in thin-and-light devices) will result in lower performance.

Attachment 43029

Intel's Tiger Lake pulls off pretty impressive performance in regular applications, especially when you consider its four core models square up against AMD's potent eight-core Ryzen 4000-series chips. Intel shared benchmarks of its chips beating the Ryzen 7 4800U in a whole range of applications, including office and productivity/creativity software. As always, we'll need to wait for more comprehensive third-party benchmarks to make a final determination.

A lot of Intel's claimed advantages stem from its big push into AI capabilities as the company works with a slew of software vendors to enable support for its newest capabilities. These new software packages yield massive improvements, up to 5X, in performance due to support for AI-boosting DL Boost instructions that leverage AVX-512 to boost performance.

Leveraging the AVX instruction set for AI workloads could evolve into a significant advantage over AMD's Ryzen 4000 processors as Intel's software support broadens. Intel's chips have long dropped into lower frequencies as densely-packed AVX instructions work their way through the processor, but Intel has reduced the impact with a new SuperMIM capacitor that keeps voltages steady. That allow the processor to remain in higher frequency ranges during heavy AVX workloads.

Intel doesn't just focus on AI workloads that run on the Willow Cove cores, though. The Gaussian and Neural Accelerator (GNA) returns, but this time with a new 2.0 revision. This SoC-integrated AI accelerator block is used for processing all sorts of low-power voice-based applications, like translation and transcription, using low-power inferencing. Intel claims that this offload engine can reduce CPU utilization by 20% during these types of operations, but at much lower power consumption. This unit can be also be used for impressive noise cancelation capabilities without taxing the Willow Cove cores.

We'll have to wait until Tiger Lake laptops hit our labs for the full rundown on battery life, but Intel claims to have made significant gains in power consumption. The chart above highlights some of the performance and efficiency improvements that come from the company's new focus on providing higher performance while the laptop is under battery power.

As you can see on the right, Intel claims that performance on the Ryzen 4000-series 4800U drops precipitously when you remove the power plug and the laptop operates on battery power alone. In contrast, Intel claims its Tiger Lake chips offer the same amount of performance, even boosting up to the full 50W of power, while on battery power. If that pans out in our testing, that means you'll still get the full Tiger Lake performance while on battery power.

Intel Tiger Lake Thunderbolt 4, PCIe 4.0 Interface, WiFi 6

After losing the glory of being the first to PCIe 4.0 on the desktop (AMD holds that distinction), Intel is the first to bring PCIe 4.0 support to laptops. The faster interface enables speedier SSD options that provide more performance and efficiency than their PCIe 3.0 counterparts.

That marks the beginning of a new era for PCIe 4.0 SSDs, and while some may opine that the speedy interface draws more power, that isn't the full story. While the PCIe 4.0 interface does draw more power than 3.0, it can transfer data at up to twice the speed per lane. That helps reduce the amount of time the interface is active, which allows the chip to drop into lower power states more quickly. Intel added the ability to shut off or dynamically adjust Tiger Lake's PCIe interface when it isn't fully active, and the faster interface could be used to employ fewer lanes during some workloads, both of which will allow you to enjoy the speed of PCIe 4.0 SSDs without making huge sacrifices on battery life.

Intel touts its support for integrated Thunderbolt 4 and USB 4, but these aren't really 'new' protocols. In short, with speeds up to 40Gb/s, Thunderbolt 4 maintains the same maximum speed rating as its predecessor (TB3) and doesn't enable new features. Instead, vendors are required to enable all of the high-end features that used to be optional, like the ability to hit the 40Gb/s data throughput requirements and support two 4K displays or one 8K display. This approach does simplify the confusing branding surrounding Thunderbolt 3, but from a hardware standpoint, the speeds and feeds remain the same.

Intel Tiger Lake Willow Cove Architecture and 10nm SuperFin Process

Intel also made some finer-grained improvements to its microarchitecture, and the resulting Willow Cove cores feature a rebalanced cache hierarchy to improve performance, dual ring bus fabric, SuperMIM capacitors, and new security enhancements, among many other improvements.

Intel pairs the new Willow Cove cores with its 10nm SuperFin process. The process offers much higher clock speeds at any given voltage, and it can also operate at a lower voltage at any given frequency, too. As a result, the chip has a greater dynamic frequency range from the minimum to maximum voltage, which provides better performance at every power level. That equates to faster mid-range performance in thin-and-light devices, not to mention peak performance in high-performance designs.

Intel Tiger Lake Iris Xe LP Graphics Engine

Intel's Xe LP (Low Power) architecture powers the Tiger Lake chips, but don't be fooled by the "Low Power" in the Xe graphics branding, though. The Xe LP graphics engine promises up to twice the performance of the previous-gen Gen11, addressing a key sore point in Intel's lineup compared to AMD's capable 7nm "Renoir" Ryzen Mobile processors with Vega graphics.

Intel's Xe LP comes with a significantly revamped architecture that we covered in our Intel Drops XE LP Graphics Specs deep dive. The net-net is that the engine comes with up to 96 execution units (EU) and 'significant' performance-per-watt efficiency improvements over the previous Gen11 graphics, which implies twice the performance at lower power compared to Intel's Ice Lake.

Intel revamped its display engine, too. Tiger Lake supports hardware acceleration for AV1 decode, up to four display pipelines, 8K UHD and Ultra Wide, 12-bit BT2020 color, and 360Hz and Adaptive Sync, among others listed in the album above. Tiger Lake also supports up to six 4K90 sensors (support starts at 4K30) and can process still images up to 42 megapixels, an increase over the prior 27MP limitation with Ice Lake.

Intel Tiger Lake Pricing and Availability

Intel says that over 50 new designs based on Tiger Lake chips will land in time for the holidays, and there will be over 150 models released in total. Unfortunately we don't have an official price list for the chips, as they are only delivered to OEMs. That means our only measure is the pricing on the devices that come to market.
