[TPU] AMD Zen 2 Offers a 13% IPC Gain over Zen+, 16% over Zen 1

Quote:
Bits n Chips has information that Zen 2 is making significant IPC gains.

According to the Italian tech publication, we could expect Zen 2 IPC gains of 13 percent over Zen+, which in turn posted 2-5% IPC gains over the original Zen. Bits n Chips notes that these IPC gains were tested in scientific tasks, and not in gaming. There is no gaming performance data at the moment. AMD is expected to debut Zen 2 with its 2nd generation EPYC enterprise processors by the end of the year, built on the 7 nm silicon fabrication process. This roughly 16 percent IPC gain versus the original Zen, coupled with higher clocks, and possibly more cores, could complete the value proposition of 2nd gen EPYC. Zen 2-based client-segment products can be expected only in 2019.

When asked on Twitter about the higher clock potential of the 7nm process, the publication said that it's "Not much higher", so I would cautiously not expect more than 4.5 Ghz (the Ryzen TR2 2950X turbos to 4.4 Ghz). So, 13%+ IPC and a cautious 4.5 Ghz max clocks, and I'd say that AMD has the potential to edge around a 5% win over the 9900K at stock.

Would the shrink to 7nm give any other gains other than just lower power consumption and slightly higher clocks? I'm honestly fine with 4.5Ghz if it means I can run it on standard cooling with all 8 cores. I'm just wondering if a die shrink gives any other IPC gains at all.

Less distance travelled means potentially less overall latencies, but that is already accounted for in the Zen 2 13% IPC gain as the Zen 2 arch only exists as a product on 7nm. We'd have to transition it to 12nm and see what the penalties would be.

The article itself states the IPC gains were tested in scientific tasks. Not productivity tasks or gaming tasks. With no independent 9900k results are out yet. So how are you getting 5% win over the 9900K, when it's unsure how the 9900K stacks against the 2700X in scientific, productivity and gaming?

We know how the 8700K performs; the 9900K has the same arch with some Meltdown and Spectre hardware fixes / mitigations that shouldn't affect performance much (at least not nearly as much compared to the current software fixes), two more cores and a higher operating all core turbo, so we can have an idea where it will land.

At the end of the day, it's all speculation and in the case of this thread an unconfirmed information / article, so take it for what it is.

so.. whats the verdict.. we get 12 or 16 core on ryzen or only 8 core??

I imagine what will happen is zen2 @4.6-4.5ghz with some IPC increase will match 9900k all while under cutting them in price. Intel 12-15% lead will vanish to margins of error.

Though we all know amd chips hit a hard clock speed limit, intel while consuming stupid amounts of power/heat will still clock 5.0-5.3 all day long. It is yet to be seen if the IPC increase can close the gap on the clock speed difference, and how this effects game performance too.

Intresting times ahead indeed. If AMD makes a better chip and finally catches intel in single core performance I will gladly sell my intel chip and jump ship.

Indeed interesting times ahead. AMD is on the record saying that they designed Zen 2 to compete favourably with Ice Lake, but in the meantime Intel has this magic card which is being able to clock Coffee Lake to the moon (let's see about power consumption), so we'll see what happens.

True it's all speculation. If the article had any info on productivity or gaming tasks at least it's some data to compare to the 2700X with Ryzen 2. Since there's plenty of 2700X benchmarks in gaming and productivity tasks a scientific estimation can be made on possible IPC gains.
