A couple of reports this week have helped cast some light on upcoming Intel Tiger Lake (TGL) CPU designs. Before we go on, to refresh your memories, TGL will be fabricated using Intel's refined 10nm+ process and deliver "double-digit performance gains, massive AI performance improvements, a huge leap in graphics performance and 4x the throughput of USB 3 with the new integrated Thunderbolt 4".

Slide from Intel CES 2020 presentation

We think the first TGL chips will appear as TGL-U parts in thin and light laptops before the summer is out. This schedule might explain the recent leaks shared by NotebookCheck and RoGame. Additionally, Intel will be discussing TGL at Hot Chips Symposium on Monday, 17th August.

Tiger Lake iGPU

An exclusive set of 3DMark Fire Strike results obtained by NotebookCheck claims to provide a window onto the uplift in TGL graphics performance compared with Ice Lake. In the chart below you can see various TGL-U iGPU configurations directly compared to Ice Lake equivalents. TGL-U Gen12 Xe iGPUs will sport 48, 80, and 96 Execution Units (EUs) with the 96-EU part also being available in a 28W TDP envelope (all the rest are 15W SoCs).

While Ice Lake's top-end Iris Plus Gen11 Graphics G7 "couldn't really hold up to the AMD Radeon RX Vega 8 in the Ryzen 7 4800U," according to NotebookCheck testing, the new GPUs are "well-poised to beat AMD at the iGPU game". Both improved architecture and higher clock speeds are believed to be in play.

Tiger Lake CPU

The TGL processors make use of Intel Willow Cove cores with IPC gains over ICL's Golden Gove cores and a refined 10nm process. A benchmark run featuring an Intel TGL-U processor was spotted by Twitter's RoGame yesterday, and it features the following configuration:

  • 4 cores / 8 threads
  • Base clock 2.3GHz
  • Turbo clock 5.0GHz
  • Intel Gen12 mobile graphics
  • Laptop vendor: Dell

It is notable that the fastest currently available ICL-U SoC, the 28W TDP Core i7-1068NG7, has a similar configuration (cores, base clock) but its max turbo speed is only 4.1GHz.

TGL-U advances in both CPU and GPU terms could be very worthy, if these CPU and iGPU leaks/rumours turn out to be true.

I strongly suspected the marketing they would use, would be to compare to their own sub par integrates gpus.

What do you mean? Current Icelake iGPUs are comparable to Vega 8 in Ryzen Mobile 3000. 2x that would be leadership.

for AMD APUs are they readying RNDA OR RDNA2?? looks like they will introduce raytracing on APUs

Intel IGPUs beating AMD ones would make for an interesting proposition in the low end - for some use cases the intel one would be the better choice (i.e. if all you're doing is gaming and web browsing, and no dGPU). This does depend on the market segmentation though, AMD is a lot more generous with GPU CUs in mid tiers so we'll probably see the high end intel iGPUs at around the same price as models with an AMD CPU (therefore 2x performance) and an actual dGPU

That is what I mean.

On price / value, power draw, etc. Intel are behind. Also comparing Intels worl on progress on a previous AMD model is just the same as Intels marketing.

AMD are also due to release ne GPUs, rumoured to be a big step up, but no one knows yet.

When they choose to make a new APU, using architecture
, should be good.

Regardless, Ir really hope Intel can pull this off, despite not deserving it, it will help the market.

2 GPU manufacturers has seriously hurt the market, competition, financially capable competitor to Nvidia as well as breathing space for AMD (in some respects), is great overall.
