AMD Introduces EPYC 4004 Series Socket AM5 Server Processors for
SMB and Dedicated Webhosting Markets
https://www.techpowerup.com/322650
AMD today introduced the EPYC 4004 line of server processors in
the Socket AM5 package. These chips come with up to 16 "Zen 4"
CPU cores, a 2-channel DDR5 memory interface, and a 28-lane PCIe
Gen 5 I/O, and are meant to power small-business servers, as well
as cater to the dedicated web-server hosting business that
generally attracts client-segment processors. This is the exact
segment of market that Intel addresses with its Xeon E-2400 series
processors in the LGA1700 package. The EPYC 4004 series offers a
superior support and warranty regime compared to client-segment
processors, besides ECC memory support, and AMD Secure Processor,
and all of the security features you get with Ryzen PRO 7000 series
processors for commercial desktops.
重點：
1. AM5腳位
2. 最高16核
3. 雙通道DDR5 支援ECC
4. 28-lane PCIe Gen 5
5. 對標Intel Xeon E-2400
AMD's offer over the Xeon E-2400 series in its CPU core count of up
to 16, which lets you fully utilize the 16-core limit of the Windows
2022 Server base license. The EPYC 4004 series is functionally the
same processor as the Ryzen 7000 "Raphael" except for its ECC memory
support. This chip features up to two 5nm "Zen 4" CCDs with up to 8
cores, each; and an I/O die that puts out two DDR5 memory channels,
and 28 PCIe Gen 5 lanes. Besides today's prcessor launch, several
server motherboard vendors are announcing Socket AM5 server boards
that are rackmount-friendly, and with server-relevant features.

The AMD EPYC 4004 series consists of eight individual processor models
based on CPU core counts and TDP. The lineup begins with the 16-core/
32-thread EPYC 4564PX (校：應為4564P), with 4.50 GHz base frequency,
up to 5.70 GHz boost, and a 170 W TDP for superior boost frequency
residence. This chip is priced at $699, which isn't all that pricier
than a Ryzen 7950X client processor. The EPYC 4584P (校：應為4584PX)
is launching at the same $699 price, with the same 16-core/32-thread
muscle, but lower 4.20 GHz base frequency, and a significantly lower
120 W TDP. Next up, is the EPYC 4464P, a 12-core/24-thread chip with
3.70 GHz base frequency, 5.40 GHz maximum boost, and a 65 W TDP. AMD
is pricing this chip at $429. The 4484PX is a faster 12-core chip, with
4.40 GHz base frequency, 5.60 GHz maximum boost, but with a 120 W TDP,
and a $599 price.
這段其實沒講到重點，簡單來說
4564P對應7950X，正常的L3和較高的base clock和TDP
4584PX對應7950X3D，加大的L3，一般的base clock和TDP
4464P對應7900，正常的L3和較低的base/boost clock和TDP
4484PX對應7900X3D，加大的L3，一般的base clock和TDP
MSRP則和對應的一模一樣

The 8-core/16-thread lineup consists of the EPYC 4364P and the 4344P.
The former ticks at 4.50 GHz base and 5.40 GHz maximum boost, with a
105 W TDP and a $399 price; while the latter does 3.80 GHz base, 5.30
GHz maximum boost, with a 65 W TDP, and a $329 price. The EPYC 4244P
is a 6-core/12-thread chip running at 3.80 GHz base, 5.10 GHz boost,
65 W TDP, and a $229 price. At the tail end is the EPYC 4124P, a
4-core/8-thread chip that ticks at the same 3.80/5.10 GHz speeds as
the 4244P, with the same 65 W TDP, but at a $149 price.
簡單來說4364P對應7700X，4344P對應7700，4244P對應7600
以及多一個4核的4124P，MSRP $149

The company also presented several performance numbers for its EPYC
4004 series, where the series shows significant performance advantage
over the Xeon E-2400 series in several server performance benchmarks.
The real ace here is AMD's core count, which scales all the way between
4 and 16, letting you maximize your Windows 2022 Server base license,
or the 16-core SQL Server license.
PPT秀了幾張效能比較，我認為重點在於
Xeon E-2488 8c/16t MSRP 609
EPYC 4364P 8c/16t MSRP 399
EPYC 4564P 16c/32t MSRP 699
至於效能比較看看就好，不如實際測試

先上我整理的表格

可以看到EPYC 4004基本上就是Ryzen 7000產品線直接搬過去
4XX4的第二個數字與核心數相關
5對應16c、4對應12c、3對應8c、2對應6c、1對應4c
第三個數字大概和定位相關
大致可以看出8對應X3D、6對應X、4對應non-X、2應該代表低階
(不過照這樣來看4464P應該要叫4444P才對，可能是太難聽了跳過？)
這次EPYC4004系列大概就是來補足低階伺服器的市場
瞄準PCIe通道數以及RAM容量較不要求的用途
而且價格也非常好看
反觀Intel那邊給的...
另外我覺得4124P這顆4核的CPU也蠻值得關注的
單核性能應該不差
如果價格開得夠低
說不定是一顆可以當入門遊戲機的CPU
